Introduction

This article is written in response to recent questions from Astrophyzix users asking how our orbital‑refinement system works, what computational methods we use, and how our visualisations achieve the same scientific fidelity seen in NASA’s SBDB Orbital Viewer. Astrophyzix does not copy and paste data or information. We use live, raw data provided by NASA and it is processed through our own systems to provide the public with an easy to understand platform without compromising the raw data. Here's how we do it. 

Astrophyzix is committed to transparent science communication. This report explains — in clear, technical detail — the numerical standards, integrators, GPU compute systems, and NASA data pipelines that power the Astrophyzix Digital Observatory.

Numerical Foundations — Float64 & IEEE‑754

Astrophyzix performs all orbital calculations using Float64, the 64‑bit floating‑point format defined by the IEEE‑754 standard. This provides:

• ~15–17 digits of precision
• stable rounding behaviour
• predictable error propagation
• compatibility with NASA Horizons and JPL SBDB data

Lower‑precision formats (Float32) introduce rounding errors that accumulate into kilometre‑scale deviations over long integrations. Float64 ensures:

• accurate MOID calculations
• stable long‑term orbit propagation
• precise close‑approach modelling
• correct gravitational‑keyhole geometry

Float64 is the same precision used by NASA, ESA, and academic orbital‑mechanics software — Astrophyzix uses it for every physics engine.

Asteroid Apophis 2029 Flyby Updated Frequently Asked Questions — Answered With Real Science by Astrophyzix Digital Observatory

Everything you need to know about Asteroid Apophis and it's 2029 Close Approach to Earth - Evidence-First Asteroid News Without Sensationalism or Hype

Introduction 

This FAQ uses verified scientific data from NASA, JPL, ESA, and peer‑reviewed research. It is designed to cut through misinformation and explain the 2029 Apophis flyby using real orbital mechanics, radar measurements, and planetary defence standards. 

Planetary Defence is a serious subject, it should be reported responsibly and with clarity. Never trust click-bait titles or sensational headlines you see online. Always consult official data from credible, trusted sources. Below are common questions people ask, answered with integrity. 

What is Apophis?

Asteroid (99942) Apophis is a near‑Earth asteroid discovered on 19 June 2004. It is an Aten‑class asteroid, meaning its orbit is smaller than Earth’s but crosses Earth’s orbital path. Apophis is classified as an S‑type stony asteroid with a diameter of roughly 340–370 metres. Radar imaging from NASA’s Goldstone facility shows Apophis has a bi‑lobed “peanut” shape, similar to other rubble‑pile asteroids.

• You can use the Astrophyzix Asteroid Lookup tool to view the live NASA data profile of Apophis. 
• See live detailed data, orbital dynamics, flyby countdown and comprehensive data sets using the Astrophyzix Live Apophis Tracker

The new V4 Astrophyzix Apophis Tracking and Monitoring tool is considered by Microsoft Bing to be the "best public Apophis tracker available online". It offers the most comprehensive tracking experience with real-time data, including the asteroid's position, speed, and potential encounters with Earth. The tool is integrated with the official NASA API and provides exclusive data sets, making it a valuable resource for both astronomers and the general public interested in the asteroid's trajectory and safety

Is Apophis going to hit Earth in 2029?

No. Astrophyzix can confirm that there is no risk in 2029. Ignore all of the click-bait and sensational headlines. Again, there is no impact risk in 2029 — you're safe. 

NASA’s orbital solutions, refined with radar data from 2020–2021, eliminated all impact trajectories for 2029, 2036, 2068, and the next 100 years. Apophis is now rated Torino Scale 0 and Condition Code 0, meaning its orbit is extremely well known. If NASA had even the slightest doubts the condition code would be higher than zero, and it isn't. 

How close will Apophis come to Earth in 2029?

On Friday 13 April 2029, Apophis will pass about 32,000 km above Earth’s surface — closer than geostationary satellites. This is roughly:

• 1/10th the distance to the Moon
• Closer than many communication satellites
• Visible to the naked eye from parts of Europe, Africa, and Asia

Why was Apophis once considered dangerous?

In 2004, astronomers had only a short observation arc. With limited data, the uncertainty region for Apophis’s orbit was large, and some early solutions intersected Earth. As more data arrived, especially radar ranging, the uncertainty collapsed and all impact scenarios were ruled out.

The Pentagon’s New UFO Archive: What the Evidence Actually Shows - Scientific Analysis Without Hype and Sensationalism

What the evidence actually shows in the newly released U.S. UAP UFO archive

Published by: Astrophyzix Digital Observatory

Evidence-First Analysis Without The Hype 

Introduction 

For decades, unidentified flying objects — now more commonly referred to as UAPs (Unidentified Anomalous Phenomena) — have occupied a strange space between national security, scientific curiosity, public fascination, and conspiracy culture. 

That conversation intensified again following the recent public release of historical UFO-related material through the U.S. government portal at war.gov/UFO.

Public Response 

The archive has already generated dramatic headlines across social media and online commentary, with some claiming the release “confirms aliens,” while others dismiss the material entirely. Neither extreme accurately reflects the available evidence.

A careful examination of the released material instead reveals something more nuanced:

 governments have spent decades investigating aerial observations they could not immediately identify, primarily because unidentified objects in restricted airspace represent potential intelligence and defence concerns. 

• That reality is important — but it is certainly not equivalent to proof of extraterrestrial visitation.

This article examines the release from an evidence-first perspective, separating verified information from speculation while evaluating what the documents actually demonstrate.

What Was Released?

The newly public archive appears to compile historical records connected to UFO and UAP investigations conducted by various U.S. government agencies over several decades. 

Reports indicate that the collection includes material linked to:

• the Department of Defense,
• military aviation incidents,
• intelligence assessments,
• radar observations,
• pilot testimony,
• and previously scattered archival records.

Coverage of the release by major outlets such as the Washington Post suggests the archive is being presented as a transparency initiative rather than a declaration of extraordinary discoveries.

Historically, UFO investigations within the United States have included:

• Project Sign,
• Project Grudge,
• Project Blue Book,
• the Advanced Aerospace Threat Identification Program (AATIP),
• and more recent Pentagon UAP review offices.

Astrophyzix Launches the Universe Expansion Simulation Tool (SIM‑09): A New Window Into Cosmic Evolution

Astrophyzix Launches Another Flagship Module - The Universe Expansion Simulation Tool 

Introduction

Astrophyzix has officially released the Universe Expansion Simulation Tool (SIM‑09) — a fully interactive FLRW cosmology engine that models the evolution of the universe across more than 13 billion years of cosmic history. Built on the ΛCDM framework and enhanced with multiple alternative cosmological presets, the tool offers a level of clarity, precision, and accessibility rarely seen outside academic research environments.

This launch marks a major expansion of the Astrophyzix Digital Observatory, extending its capabilities beyond Live NEO/PHA tracking, impact modelling, orbital dynamics and supernova simulations into the domain of large‑scale cosmology.

What the Tool Does

The Universe Expansion Simulation Tool models the evolution of the scale factor a(t) under the Friedmann–Lemaître–Robertson–Walker (FLRW) metric. Users can explore how the universe expands, decelerates, accelerates, or collapses depending on the values of:

• H₀ (Hubble constant)
• Ωₘ (matter density)
• Ωᵣ (radiation density)
• ΩΛ (dark‑energy density)
• w (dark‑energy equation of state)

The simulation integrates the Friedmann equation in real time, producing:

• A dynamic comoving particle field
• A scale‑factor vs. cosmic‑time graph
• Real‑time values of H(t), q(t), z, and t
• A predicted asymptotic fate of the universe

This makes the tool both visually compelling and scientifically rigorous.

Key Capabilities

• Interactive ΛCDM evolution
  Adjust cosmological parameters and instantly see how the universe’s expansion history changes.

• Multiple cosmological presets
  Including PLANCK 2018, SHOES (Hubble tension), Einstein‑de Sitter, and Closed Universe models.

• Dynamic cosmic‑fate prediction
  The tool determines whether the universe ends in Heat Death, Big Crunch, Open Coasting, or Big Rip, depending on the chosen parameters.

• Real‑time FLRW integration
  Uses a stable fourth‑order Runge–Kutta method and Simpson quadrature for cosmic age calculations.

• Comoving field visualisation
  A 12 Mpc reference field shows galaxies drifting apart (or collapsing) according to the scale factor.

• Scientific documentation
  A full Governance & Methodology section explains the equations, assumptions, numerical methods, and validation benchmarks.

The module is powered by real astrophysical equations, peer‑reviewed models, and a direct N‑body gravitational integrator.

A Real‑Time Window Into Planetary Formation

SolarForm simulates the early stages of solar system formation using physically grounded models drawn from astrophysics, celestial mechanics, and planetary science. Users can watch a nebular disk evolve dynamically as bodies collide, merge, accrete, and migrate under gravity.

Key features include:

• N‑body gravitational physics using a velocity‑Verlet symplectic integrator.
• Planetesimal growth and accretion through inelastic collisions with gravitational focusing.
• Protoplanetary disk density profiles based on the Minimum Mass Solar Nebula (MMSN).
• Keplerian orbital initialization scaled by nebula mass and angular momentum.
• Snowline physics determining where ice bodies and gas giant cores can form.
• Real‑time classification of bodies into planetesimals, proto‑planets, rocky planets, and gas giants.

The simulation updates continuously, allowing users to observe the chaotic, emergent behaviour of early planetary systems as they stabilize over time.

The Buga Sphere Has NOT Been Confirmed to be 12,560 Years Old Using Carbon Dating - Here is What The Science Really Says

The “Buga Sphere” Dating Claim Examined: A Forensic Analysis of the Evidence

📌 Cited by:  - Enigmaticideas.com

Written by: Astrophyzix Digital Observatory

Key Takeaways

• There is no verifiable scientific evidence that the “Buga Sphere” is 12,560 years old
• The reported radiocarbon dating applies to organic residue, not the object itself
• No institutional confirmation from the University of Georgia can be verified
• No peer-reviewed studies, laboratory reports, or reproducible analyses exist
• All claims of advanced technology remain unsupported by material evidence

Introduction

In early 2026, renewed attention was directed toward an object commonly referred to online as the “Buga Sphere.” Claims circulated suggesting that the object had been scientifically dated to approximately 12,560 years before present, with references made to testing allegedly conducted by the University of Georgia using Accelerator Mass Spectrometry (AMS).

These claims have been widely shared across non-scientific platforms, often accompanied by interpretations involving advanced technology, lost civilisations, or anomalous origins. This article examines those assertions using established scientific methodology, with particular focus on dating techniques, evidential standards, and verification requirements.

What is Galaxy Season? Everything you Need to Know About Galaxy Season Explained

What Is Galaxy Season? A Global Guide to the Best Time for Observing the Deep Universe

Written by: Astrophyzix Digital Observatory 

What is Galaxy Season? 

“Galaxy season” is an informal but widely used term in observational astronomy referring to the time of year when the night sky provides the clearest and most unobstructed view of distant galaxies beyond our home system, the Milky Way. For observers in the Northern Hemisphere, this period typically spans from March through May, while in the Southern Hemisphere, an equivalent window occurs later in the year.

This seasonal phenomenon is not caused by any intrinsic change in galaxies themselves, but rather by Earth’s orbital position and the resulting orientation of the night sky. During galaxy season, observers are effectively looking out of the dense plane of the Milky Way and into deeper intergalactic space, where distant galaxies become far more visible.

• Occurs annually due to Earth’s orbital geometry
• Maximizes visibility of extragalactic objects
• Favours low-dust, low-star-density regions of the sky
• Critical for both amateur and professional deep-sky observation

The Definitive Guide To Telescope Eyepieces and the Best Options Available in 2026

Astrophyzix Digital Observatory Equipment Guide · 2026

Written by: Astrophyzix Digital Observatory NON-SPONSORED ARTICLE

Best Eyepieces for Telescopes 2026

The eyepiece is the final optical element between the telescope and your eye. It determines magnification, apparent field of view, eye relief, and image contrast -- and a poor eyepiece will waste the potential of even a well-made telescope. Most instruments ship with one or two basic eyepieces that are adequate for initial use but represent genuine limitations on what the telescope can show.

This guide covers the physics of eyepiece selection, explains what the specifications actually mean, and recommends specific eyepieces across three budget tiers -- all available on Amazon UK.

Eyepiece Physics: What the Specifications Mean

Magnification is calculated by dividing the telescope focal length by the eyepiece focal length. A 25 mm eyepiece in a 1000 mm telescope produces 40x magnification. A 10 mm eyepiece in the same telescope produces 100x.

Magnification = Telescope focal length (mm) / Eyepiece focal length (mm)

Apparent field of view (AFOV) is the angular diameter of the image circle you see through the eyepiece, measured in degrees. Standard Plossl designs offer around 50 degrees. Wide-angle designs range from 65 degrees to over 100 degrees. A wider AFOV provides a more immersive view and makes it easier to keep objects in frame during manual tracking.

True field of view (TFOV) is the actual patch of sky visible, calculated as AFOV divided by magnification. A 25 mm eyepiece with a 50 degree AFOV in a 1000 mm telescope gives a TFOV of approximately 1.25 degrees -- wide enough to frame the full Moon with space to spare.

True field of view (degrees) = Apparent field of view / Magnification

Eye relief is the distance from the eyepiece eye lens to the point at which the full field of view is visible. Short eye relief (below 10 mm) makes comfortable viewing difficult and is particularly problematic for observers wearing glasses. Premium eyepieces typically offer 15 mm or more of eye relief across all focal lengths.

Exit pupil is the diameter of the light beam exiting the eyepiece. Values above 7 mm exceed the dark-adapted human pupil and waste light. Values below 0.5 mm produce very dim images. The optimal range for most observing tasks is 1.5--5 mm.

Exit pupil (mm) = Eyepiece focal length (mm) / Telescope focal ratio (f/number)

Practical guidance Three eyepieces cover the majority of observing tasks: a low-power wide-field eyepiece for finding targets and large objects (around 30--40 mm), a mid-power eyepiece for nebulae and galaxies (around 15--20 mm), and a high-power eyepiece for lunar and planetary detail (around 6--10 mm). A 2x Barlow lens doubles any of these, effectively providing six magnifications from three eyepieces.

Budget Under £40 per eyepiece

Budget eyepieces have improved substantially in recent years. The options below deliver genuine optical quality and are appropriate for beginners building a first collection or observers testing focal lengths before investing in premium glass.

Wide-field / low power · Budget

Celestron Omni 32 mm Plossl

32 mm focal length 50° AFOV 1.25" barrel 4-element Plossl

The 32 mm Plossl is the standard recommendation for a wide-field finder eyepiece in any 1.25 inch focuser. It provides the widest true field of view achievable with a 1.25 inch barrel -- typically around 1.5--2 degrees depending on focal length -- making it ideal for locating objects, sweeping star fields, and viewing large targets such as the Pleiades, the Orion Nebula, and the Andromeda Galaxy. The Celestron Omni version uses consistent four-element optics and solid metal construction.

Verdict The most useful single eyepiece a beginner can own. Almost every telescope benefits from a quality 32 mm Plossl as a starting point, and this one delivers reliable performance at a price that leaves budget for other focal lengths.

Strengths

• Widest practical TFOV in 1.25"
• Sharp, consistent optics
• Works on any telescope type
• Solid metal construction

Limitations

• Narrow 50° AFOV
• Not ideal for high power

>> View on Amazon UK

Deep-sky / mid power · Budget

SVBONY Goldline 15 mm

15 mm focal length 66° AFOV 1.25" barrel Multi-coated

The SVBONY Goldline series is among the most consistently recommended budget eyepieces in the UK amateur astronomy community. The 66-degree apparent field of view is significantly wider than a standard Plossl, and the 15 mm focal length sits in the productive mid-power range for galaxy and nebula work. The optical quality is well above what the price suggests -- sharp on axis in telescopes of f/6 and above, with acceptable edge performance.

Verdict Exceptional value. The Goldline 15 mm is the most recommended budget mid-power eyepiece across UK astronomy forums and regularly outperforms comparably priced Plossl designs in field tests. A strong first upgrade for observers stepping beyond the eyepieces supplied with their telescope.

Strengths

• 66° AFOV -- significantly wider than Plossl
• Sharp on-axis performance
• Comfortable eye relief
• Outstanding price-to-quality ratio

Limitations

• Edge performance degrades below f/5
• Not ideal for fast Newtonians

>> View on Amazon UK

Planetary / lunar · Budget

SVBONY Goldline 6 mm

6 mm focal length 66° AFOV 1.25" barrel Built-in Barlow element

The Goldline 6 mm is the high-power companion to the 15 mm and provides genuine planetary magnification at minimal cost. Its internal Barlow element achieves the short focal length while maintaining comfortable eye relief -- a design advantage over traditional short Plossls, which become difficult to use below 10 mm. Performs best in telescopes of f/8 and above; in faster instruments some on-axis softness is visible.

Verdict The best budget high-power eyepiece for lunar crater detail, Jupiter's cloud bands, and Saturn's ring structure. Outperforms stock eyepieces at this magnification level in the vast majority of beginner telescopes.

Strengths

• Comfortable eye relief at short FL
• Sharp planetary views in slow scopes
• Wide AFOV for its price class

Limitations

• Softer in fast telescopes (f/5 or below)
• Not suitable for astrophotography

>> View on Amazon UK

Mid-range £40--£150 per eyepiece

Mid-range eyepieces offer measurably improved edge correction, wider apparent fields, and better eye relief than budget options. They are appropriate for observers who have identified their preferred focal lengths and want to commit to longer-term quality.

All-purpose zoom · Mid-range

Celestron 8--24 mm Zoom

8--24 mm zoom range 40--60° AFOV 1.25" barrel Fully multi-coated

A zoom eyepiece replaces three or four fixed focal lengths with a single continuously variable instrument, making it particularly useful for planetary observing where seeing conditions fluctuate and the optimal magnification changes throughout a session. The Celestron 8--24 mm is the most widely recommended zoom in the mid-range bracket, with reliable optics, consistent eye relief across the zoom range, and a rubberised grip for cold-weather use.

Verdict The most practical single eyepiece for planetary and lunar work. Rather than swapping fixed eyepieces to chase the best seeing, the observer simply rotates the barrel. Recommended as the first mid-range purchase for observers who already own a wide-field Plossl.

Strengths

• Replaces 3--4 fixed eyepieces
• Consistent eye relief throughout zoom
• Excellent for variable seeing conditions
• Works well with Barlow lenses

Limitations

• AFOV narrows at maximum zoom
• Slight image shift when zooming

>> View on Amazon UK

Wide-field deep-sky · Mid-range

Celestron X-Cel LX 25 mm

25 mm focal length 60° AFOV 1.25" barrel 16 mm eye relief Fully multi-coated

The X-Cel LX series is Celestron's mid-range line and addresses the main shortcomings of budget Plossls: generous eye relief at 16 mm (comfortable for spectacle wearers), a 60-degree apparent field that feels noticeably wider than a Plossl, and good edge sharpness across a range of focal ratios. The 25 mm is the most versatile focal length in the series -- low enough power to frame large objects, high enough to begin showing nebula structure.

Verdict The best mid-range choice for observers who wear glasses or who find short eye relief tiring during extended sessions. Produces noticeably better edge-of-field performance than budget equivalents, and the 60-degree field provides a more immersive experience than a standard Plossl.

Strengths

• 16 mm eye relief -- excellent for glasses wearers
• 60° AFOV with good edge correction
• Works across f/5 to f/15
• Solid build quality

Limitations

• Narrower field than premium wide-angles
• Not the sharpest at fast focal ratios

>> View on Amazon UK

Premium zoom · Mid-range / upper

Baader Hyperion Zoom Mark IV 8--24 mm

8--24 mm zoom range 50--68° AFOV 1.25" barrel Clickstop positions Click-fit 2x Barlow compatible

The Baader Hyperion Zoom Mark IV is the most recommended zoom eyepiece at this price level among experienced UK observers. Unlike most zoom designs, its apparent field of view widens at lower magnification (68 degrees at 24 mm) and narrows at higher magnification (50 degrees at 8 mm) -- the inverse of the Celestron zoom, and more optically natural. Clickstop positions at defined focal lengths allow repeatable magnification settings. A dedicated 2x click-fit Barlow extends the range to 4--12 mm.

Verdict The benchmark zoom eyepiece for serious visual observers. More optically refined than the Celestron zoom with better edge correction and a more logical field relationship across the zoom range. Represents a long-term investment that will outlast multiple telescope upgrades.

Strengths

• Wider field at lower power (more natural)
• Clickstop focal length positions
• Superior edge correction
• Compatible with Baader click-fit Barlow

Limitations

• Significantly more expensive than Celestron zoom
• Heavier than fixed eyepieces

>> View on Amazon UK

Premium £150 and above per eyepiece

Premium eyepieces deliver wider apparent fields, better edge-to-edge correction, higher contrast, and greater eye relief than mid-range equivalents. The difference is most visible at fast focal ratios (f/4--f/6) and in large-aperture instruments. These eyepieces are long-term investments -- they retain their value well and will remain usable regardless of telescope upgrades.

Premium wide-field · Deep-sky

Baader Morpheus 17.5 mm

17.5 mm focal length 76° AFOV 1.25" / 2" barrel 20 mm eye relief Phase-corrected coatings

The Baader Morpheus series occupies a strong position between mid-range and premium, delivering 76-degree apparent fields with sharp, high-contrast images across the full field of view -- including at fast focal ratios where many mid-range designs show edge degradation. The 17.5 mm is the most versatile focal length in the range: low enough power for expansive deep-sky views, high enough for structural detail in bright nebulae and globular clusters. The 20 mm eye relief is excellent for comfortable long-session observing.

Verdict The most consistently praised premium eyepiece in the UK community at this price point. Competes directly with designs costing significantly more and is particularly strong in fast Dobsonians where wide-field edge correction matters most.

Strengths

• 76° AFOV with sharp edge correction
• 20 mm eye relief -- excellent comfort
• Works well in fast (f/4--f/5) scopes
• Dual 1.25" / 2" barrel

Limitations

• Heavier than single-size eyepieces
• Premium price reflects premium quality

>> View on Amazon UK

Premium planetary · High power

Tele Vue Nagler Type 6 13 mm

13 mm focal length 82° AFOV 1.25" barrel 12 mm eye relief 7-element optical design

Tele Vue's Nagler series is regarded as the benchmark against which wide-angle planetary eyepieces are measured. The 82-degree apparent field of view produces what observers describe as a spacewalk effect -- the sensation of floating in space rather than looking through a tube. The 13 mm focal length places it in the optimal magnification range for planetary detail and bright deep-sky objects, and the seven-element optical design maintains sharpness across the full field even at fast focal ratios.

Verdict The most technically accomplished eyepiece in this guide. For observers who have exhausted mid-range options and want the highest possible wide-field planetary performance, the Nagler 13 mm delivers a viewing experience that is qualitatively different from anything at a lower price point.

Strengths

• 82° AFOV -- the widest-field standard
• Sharp to the edge at any focal ratio
• Outstanding planetary contrast
• Retains resale value exceptionally well

Limitations

• Significant cost
• Heavier than most eyepieces
• 12 mm eye relief -- borderline for glasses wearers

>> View on Amazon UK

Essential Accessory: The Barlow Lens

A Barlow lens inserts between the telescope focuser and the eyepiece, multiplying the telescope's effective focal length and therefore doubling (or trebling) the magnification of any eyepiece used with it. A 2x Barlow effectively doubles the size of any eyepiece collection. The Celestron Omni 2x Barlow is the most recommended mid-quality option on Amazon UK at this function.

Accessory · Doubles any eyepiece magnification

Celestron Omni 2x Barlow Lens

2x magnification factor 1.25" barrel Fully multi-coated Threaded for filters

A quality Barlow doubles the effective number of magnifications in any eyepiece collection without adding proportional cost. Paired with a 32 mm, 15 mm, and 6 mm eyepiece, a 2x Barlow provides six distinct magnifications. The Celestron Omni Barlow uses fully multi-coated optics that minimise light loss, and its filter threads allow colour or neutral density filters to be attached at the Barlow rather than the eyepiece.

Verdict The highest-value single accessory for any telescope owner. Purchasing a quality Barlow before adding more fixed eyepieces is the most cost-efficient strategy for expanding magnification range.

Conclusion

The most cost-effective eyepiece strategy is to begin with three focal lengths -- wide, mid, and high power -- and a quality Barlow, then upgrade individual focal lengths to mid-range or premium glass once preferred magnifications are identified. Spending on a premium eyepiece at a focal length rarely used is less productive than owning mid-range glass across the magnifications used most often.

Eyepieces are telescope-independent: they retain their utility regardless of what instrument they are used with, making quality glass a durable long-term investment in the hobby.

Debunking the 3I/ATLAS 'NASA was Wrong' Myth: What the Science Really Says and how Obital Refinement Works. 

In late 2025, the interstellar visitor 3I/ATLAS captured worldwide attention—not just from astronomers, but from social media, sensational headlines, and speculation about its origin and behaviour. Some videos and posts claimed that NASA was “wrong” about the object’s trajectory, implying dramatic course changes, artificial propulsion, or even extraterrestrial technology. This article corrects those myths with clear, evidence‑based science from credible observational campaigns and peer‑reviewed research.

What is the Geoid? 

Images of a distorted, lumpy Earth (as above) occasionally circulate across social media with captions claiming that the image shows the planet “as it really looks.” In reality, these images are scientific visualisations of Earth’s geoid—a model that represents the structure of the planet’s gravity field rather than its physical surface. While the visualisation appears dramatic, the actual deviations from Earth’s average radius are extremely small when viewed on planetary scales.

Prelude: From Imagination to Inquiry

Humanity’s relationship with the sky began long before the first rocket engine ignited. Ancient cultures developed sophisticated astronomical systems to interpret celestial motion, embedding the heavens within scientific, agricultural, and mythological frameworks. Although these early traditions were not attempts to leave Earth, they established the intellectual curiosity that would eventually make spaceflight conceivable.

Confirmed Binary and Triple Near-Earth Asteroids

Introduction

Near-Earth asteroids (NEAs) are small rocky bodies whose orbits bring them close to Earth. Recent radar and optical observations have revealed that many of these objects exist not as solitary rocks but as binary or triple systems, where two or three bodies orbit one another. This article examines the confirmed cases of such systems, presenting only verified, peer-reviewed findings to provide an accurate, factual overview of their physical properties, orbital dynamics, and significance for planetary science.

Introduction: What Meteoroids Are

Meteoroids are small solid particles, ranging from sub-millimeter sizes up to meter-scale bodies, that intersect Earth's orbit and produce visible meteors when they ablate in the atmosphere. Determining whether such particles originate inside the Solar System or from interstellar space requires reconstructing their pre-atmospheric orbit. 

A recent online essay by Professor Avi Loeb of Harvard University on his Medium Blog highlighted two fireball events with inferred trajectories that could be interpreted as unbound relative to the Sun’s gravity, sparking public interest. 

Debunking “Space is Fake”: Science, Satellites, and Conspiracies Explained

Written by: Astrophyzix Science Communication
Article Type: Evidence-Based Myth Correction, Explainer

 

Introduction: Space is what?!?

In recent years, a growing number of online videos, posts, and social media threads have claimed that "space is fake." Proponents of these ideas argue that NASA, ESA, and other space agencies are fabricating images, videos, and scientific data, and that astronauts, satellites, and planetary missions are elaborate hoaxes. While sensational, these claims are not supported by scientific evidence. 

This article examines the psychological, technological, and observational evidence that demonstrates why space exploration is real, and why the so-called "space is fake" narratives fail scientifically.
