Hubble Space Telescope Tracks 25 Years Of Expansion In Crab Nebula
The recent observations have helped the scientists to track the growth of the Crab Nebula by comparing images taken decades apart.

NASA's X-Ray Mission Unveils Fresh Insights Into 2,000-Year-Old Supernova
In a recent study, the Imaging X-ray Polarimetry Explorer (IXPE) observed the supernova's outer region.

Hubble Constant Puzzle Deepens as Supernova and CMB Measurements Clash
Astronomers are testing a new way to measure the universe’s expansion rate using the gravitational-wave background detected by NANOGrav. By treating the cosmic hum from merging supermassive black holes as a statistical “stochastic siren,” researchers hope to calculate the Hubble constant and help resolve the long-standing Hubble tension betwe...

Astronomers Witness Rare Failed Supernova in Andromeda Galaxy
NASA’s NEOWISE infrared telescope has provided striking evidence that a massive star in the Andromeda galaxy collapsed directly into a black hole without exploding as a supernova. The star, M31-2014-DS1, faded dramatically in visible light while leaving a faint infrared glow from surrounding dust. Astronomers say this rare “failed supernova” ...

Astronomers Look to the Large Magellanic Cloud to Study How Stars Are Born
The Large Magellanic Cloud is a nearby dwarf galaxy glowing with star birth. Just 160,000 light-years away, it hosts vast nebulae like the Tarantula and historic events such as Supernova 1987A, offering astronomers a rare, close-up laboratory to study how stars form, evolve, and explode.

NASA Finds Most Distant Calm Galaxy Cluster Ever Seen in Early Universe
Astronomers using NASA’s Chandra X-ray Observatory have discovered SPT-CL J2215-3537, a massive galaxy cluster located 8.4 billion light-years away. Nicknamed the “Champagne Supernova” cluster, it is the most distant relaxed cluster ever observed, showing no signs of recent collisions. Its calm structure and active star formation challenge ex...

JWST Spots Most Distant Supernova Ever, From 730 Million Years After Big Bang
Scientists have confirmed the most distant supernova ever observed, exploding just 730 million years after the Big Bang. Detected through a powerful gamma-ray burst and later verified by the James Webb Space Telescope, the event offers a rare glimpse of the deaths of the universe’s first stars during the era of reionisation and challenges expecta...

Betelgeuse and the Crab Nebula Reveal Stellar Death and Rebirth in Multi-Telescope Views
Betelgeuse’s unusual dimming and the Crab Nebula’s remnants offer insight into stellar death and rebirth. Composite images from multiple telescopes show gas filaments and a neutron star, illustrating how massive stars explode, enrich space with heavy elements, and seed future star formation. These observations help scientists trace stellar life...

James Webb Telescope Finds Evidence Of Giant "Dinosaur" Stars From Early Universe
The research also suggests that these massive stars transformed directly into black holes at the end of their lives without undergoing a supernova explosion.

AIIMS-Led Trial Confirms Supernova Stents Safety And Efficacy For Stroke Patients
The Supernova Stent -- a new and advanced brain treatment device -- has been demonstrated to be safe and effective for stroke patients, said experts at AIIMS Delhi on Saturday, who led the first clinical trial.
