ISRO’s AstroSat Observes First-Ever Nuclear Explosion in Andromeda Galaxy
Using the Ultraviolet Imaging Telescope (UVIT) aboard ISRO’s AstroSat, scientists have identified far-ultraviolet emissions from 42 novae in the Andromeda Galaxy. This marks the first detection of such emissions during their outbursts, offering new insights into the processes of stellar explosions. Four of these novae were observed in real-time a...

Supernova SN 1181 Reveals Rare “Zombie Star” in Pa 30 Nebula
A supernova recorded in 1181, known as SN 1181, has been linked to the Pa 30 nebula, revealing a rare “zombie star.” Advanced 3D imaging from the Keck Observatory has shown unusual filaments expanding from this star, marking it as a unique case in supernova studies. This zombie star survived a thermonuclear explosion on a white dwarf, challengi...

Supermassive Black Hole Jets Spark Increased Nova Explosions, Hubble Discovers
Recent findings from the Hubble Space Telescope reveal that supermassive black hole jets may be responsible for an increase in nova explosions in nearby double-star systems. This unexpected connection indicates that the energetic jets emitted by black holes can influence the surrounding stellar environment, leading to heightened activity in nova er...

"Once-In-A-Lifetime" Cosmic Explosion Will Be Visible From Earth, Says NASA
The "Blaze Star," which is a binary system in the Northern Crown about 3,000 light years from Earth, is comprised of a white dwarf, an Earth-sized remnant of a dead star with a mass comparable to the sun.

This Star Explosion To Be "Once-In-A-Lifetime" Cosmic Event, Says NASA
Known as "the blaze star," T Coronae Borealis is one of the galaxy's ten known recurring novas

Researchers Study Kilonova, The Explosion Behind The Birth Of Gold
The team of researchers crafted a model based on their 2017 study of the recorded kilonova explosion.

A Cosmic Blast "Temporarily Destroyed" Some Of Earth's Ozone Layer In 2022: Scientists
In a mind-boggling discovery, scientists have found that a supernova explosion billions of light years away was so powerful that it "temporarily destroyed" some of the Earth's ozone layer in 2022.

NASA's X-Ray Telescopes Capture Mysterious 'Ghost Hand' In Space
NASA's new X-ray telescope observed the haunting 'bones' of a ghostly cosmic hand 16,000 light-years from Earth for a record 17 days.

Largest Cosmic Explosion Ever, Raging For 3 Years, Spotted By Astronomers
Last year, astronomers witnessed the brightest explosion on record - a gamma-ray burst known as GRB 221009A.

Largest Cosmic Explosion That Occurred 8 Billion Light Years Away Detected
Astronomers have discovered the largest cosmic explosion that has ever been witnessed. The event took place eight billion light years away from Earth and lasted for three years.

Dormant Black Hole Deemed ‘Needle in a Haystack’ Identified Outside the Milky Way
Astronomers have identified a black hole that not only is classified as dormant but appears to have been born without the explosion of a dying star, in a galaxy adjacent to the Milky Way. Black holes are extraordinarily dense objects with gravity so intense not even light can escape. Deemed a cosmic "needle in a haystack", the newly discovered ‘d...

Spectacular Gamma Radiation From Collapse Of Dying Star Could Change Understanding Of The Universe
Scientists have recorded a cosmic explosion of gamma radiation from a collapsing star that challenges the established theory of gamma-ray bursts. The scientists said that these explosions occur when a massive star abruptly detonates and turns into a black hole.

Cosmic Explosions Even More Powerful Than First Thought: Study
The biggest explosions since the Big Bang set the universe in motion some 13 billion years ago produced even more energy than first thought, scientists said Wednesday.

This Suspected Supernova Is 570 Billion Times As Bright As Our Sun
A small, bright object that first flared up in June could be the brightest, most powerful supernova ever spotted by astronomers. If it is indeed a supernova, the object ASASSN-15lh pushes the upper limits of what scientists thought exploding stars were capable of. And if it's not a supercharged supernova, it may be something even more mysterious.
