JWST and Chandra Captures a Collision Between Two Spiral Galaxies
Jan 2, 2026
Soumyadeep Mukherjee
Galaxy interactions drive much of the structural evolution seen in the modern universe. Gravitational encounters reshape disks, compress gas, and regulate star formation over cosmic…
Festival in Space: Chandra’s Four Holiday Images Released
Jan 1, 2026
Soumyadeep Mukherjee
High-energy astrophysics rarely reaches the public in an intuitive visual form. X-ray astronomy deals with extreme temperatures, violent interactions, and invisible radiation. Yet every December,…
AT2025ulz: Did Gemini Observatory Capture a Superkilonova Explosion?
Dec 30, 2025
Soumyadeep Mukherjee
Time-domain astronomy now operates in a regime where optical surveys and gravitational-wave detectors observe the sky simultaneously. This convergence has transformed how transient events are…
A Neighbouring Vista of Stellar Birth: Hubble Captures Active Star Formation
Dec 30, 2025
Soumyadeep Mukherjee
Star formation unfolds inside cold, unstable clouds of gas, shaped by gravity, radiation, and turbulence over millions of years. On 29 December 2025, the Hubble…
Gemini and Blanco Detect the Longest Gamma-Ray Burst Ever
Dec 28, 2025
Soumyadeep Mukherjee
Gamma-ray bursts are brief, intense releases of high-energy radiation produced during catastrophic astrophysical events. They are detected as sudden spikes in gamma-ray flux, followed by…
NASA’s Europa Clipper Captures Uranus Using a Star Tracker
Dec 26, 2025
Soumyadeep Mukherjee
Deep-space spacecraft spend years in transit before reaching their scientific targets. During this long cruise, engineers rely on constant system verification to ensure mission readiness….
NGC 646: Euclid Mission Captures a Dynamic Galaxy Garland
Dec 26, 2025
Soumyadeep Mukherjee
High-resolution imaging remains one of the most effective tools for understanding galaxy structure and evolution. When combined with uniform sky coverage and photometric stability, it…
Hubble Reveals the Largest Known Planet-Forming Disc
Dec 25, 2025
Soumyadeep Mukherjee
Protoplanetary discs form as a natural outcome of star formation. Angular momentum conservation causes collapsing molecular cloud material to flatten into a rotating disc around…
How a Young Star Launches Supersonic Jets: ALMA’s New Image of SVS 13
Dec 24, 2025
Soumyadeep Mukherjee
Jets are a natural consequence of star formation. When gas collapses to form a young star, angular momentum builds rapidly. That momentum must be removed…
Gemini North Reveals Green Glow in Interstellar Comet 3I/ATLAS
Dec 23, 2025
Soumyadeep Mukherjee
Observations of small bodies on hyperbolic orbits provide direct evidence of material formed outside the solar system. Comet 3I/ATLAS is one such object. Identified through…
