James Webb Space Telescope Finds Unexpected Ultraviolet Radiation Around Young Protostars
Astronomers using the James Webb Space Telescope have detected unexpected ultraviolet radiation around five young protostars in the Ophiuchus molecular cloud. Since infant stars are not expected to emit UV light, the finding challenges long-standing star-formation models. Researchers ruled out external illumination from nearby stars, concluding the...

Fermi Telescope Detects Gamma-Ray Halo That Could Be First Direct Dark Matter Signal
NASA’s Fermi Gamma-ray Space Telescope has detected a faint halo of high-energy gamma rays around the Milky Way’s centre—matching predictions for dark-matter annihilation. The finding, reported by Professor Tomonori Totani, could represent the first direct glimpse of dark matter, but scientists caution that alternative explanations remain and...

Scientists May Have Caught The First Real Glimpse Of Dark Matter, Universe's Most Elusive Ingredient
The new study led by Prof Tomonori Totani of the University of Tokyo analysed Fermi telescope observations of the Milky Way's centre - the region where dark matter is expected to be densest.

Dark Matter May Have Been Seen for the First Time in NASA Gamma-Ray Data
A new analysis of NASA’s Fermi telescope data reveals a faint gamma-ray halo around the Milky Way’s core, matching predictions for annihilating dark-matter particles. Researchers say no known astrophysical source fits the signal, raising the possibility of the first direct evidence of dark matter. Experts, however, stress caution and call for v...

Comet C/2025 K1 (ATLAS) Breaks Into Three Pieces Following Close Approach to the Sun
NASA's fractured comet C/2025 K1 (ATLAS) dazzled stargazers on Monday night, offering a rare live view of a cosmic object breaking apart after a close encounter with the Sun. The livestream, organised by the Virtual Telescope Project, began at 10 p.m. EST on November 24 (0300 GMT on November 25) and will broadcast telescopic views of the comet's mu...

James Webb Telescope May Have Discovered Universe’s Earliest Supermassive Black Hole
James Webb may have discovered the universe’s earliest supermassive black hole in galaxy GHZ2. Observations reveal high-energy emission lines, challenging existing models of rapid black hole and galaxy growth. Upcoming JWST and ALMA studies aim to confirm AGN activity and refine our understanding of early cosmic evolution.

NASA’s Nancy Grace Roman Space Telescope Surpassing Expectations Even Before Launch, Reveals Research
NASA’s upcoming Roman Space Telescope is expected to measure seismic waves in over 300,000 red giant stars, far greater than early predictions. These signals will help scientists better understand exoplanet systems and the Milky Way’s ancient core. Researchers say Roman’s natural survey design enables this breakthrough even before the telesco...

Do Aliens Exist? India, Japan Team Up To Answer Question With Giant Telescope
The goal of the Thirty Metre Telescope project is to peer deeper into the cosmos than ever before, studying black holes, distant galaxies, and, most intriguingly, searching for signs of life beyond Earth.

Astronomers Record First-Ever Massive Stellar Blast Capable Of Stripping Planetary Atmospheres
This event originated from a red dwarf star, which is much dimmer, cooler, and smaller than the Sun.

Webb’s Stunning View of Apep Shows a Rare Triple-Star System Wrapped in Spirals
Webb’s mid-infrared images of Apep reveal a rare triple-star system producing vast carbon-rich dust spirals from colliding stellar winds. The two Wolf–Rayet stars and a distant supergiant create layered shells that record centuries of activity and enrich the galaxy with elements vital for future stars and planets.

NASA Launches Rescue Mission to Save the Swift Gamma-Ray Burst Observatory
NASA is preparing an unprecedented mission to save the Neil Gehrels Swift Observatory, a key gamma-ray burst monitor launched in 2004 but now rapidly losing altitude. Partnering with Katalyst Space Technologies, NASA will send a robotic servicer on a Pegasus XL rocket to rendezvous with Swift, inspect it, and raise it to a stable orbit. The effort ...

ESA’s Euclid Telescope Charts Over a Million Galaxies in Landmark First Data
ESA’s Euclid space telescope has captured about 1.2 million galaxies in its first year, providing one of the most detailed wide-field surveys of the universe ever made. Covering distances up to 10 billion light-years, Euclid’s clear, expansive imaging is helping astronomers study galaxy shapes, mergers, dwarf galaxy populations, and the role of...
