Exoplanets — A Comprehensive Scientific Review

The detection of planets orbiting stars beyond our Solar System — known as exoplanets — has reshaped astronomy over the past three decades. Prior to 1992, only indirect speculation existed about planets around other stars. Today, nearly 6,000 exoplanets have been confirmed through a variety of observation techniques, revealing planetary systems that challenge traditional theories of formation and habitability.

NASA’s SPHEREx Mission Tracks Interstellar Comet 3I/ATLAS Through Infrared Eyes

NASA’s SPHEREx mission — the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer has provided one of the most detailed infrared views yet of the interstellar comet 3I/ATLAS. As this rare visitor passed through our solar system, SPHEREx measured the light emitted by the gases and dust around the comet’s nucleus, revealing how its frozen materials reacted to solar heating and offering insight into the composition of a body formed around another star.

The Search for Life on Mars: A Scientific Deep-dive into Missions, Discoveries, and the Quest for Biosignatures on The Red Planet

Introduction: The Search for Life on Mars

Mars is the most intensively studied world in the Solar System in humanity’s quest to determine whether life exists beyond Earth. Its ancient evidence for liquid water, diverse geological environments, and detectable organic compounds make it a leading target for astrobiology. Life detection involves identifying robust biosignatures—features that can only be explained by biology. The scientific challenge is to distinguish these from abiotic (non‑life) chemical and geological processes, which often produce similar signals.

The Local Hot Bubble (LHB) : Our Solar System’s Superheated Galactic Neighborhood

A Million-Degree Echo of Long-Dead Stars

Introduction 

The Solar System is not drifting through empty, featureless space. Instead, it resides inside a vast, invisible cavity known as the Local Hot Bubble (LHB), a region of unusually hot and extremely diffuse interstellar gas that shapes our cosmic environment in subtle but important ways.
