James Webb Space Telescope Detects Supernova From 11.4 Billion Years Ago
Astronomers using the James Webb Space Telescope (JWST) have identified AT 2023adsv, a supernova that occurred 11.4 billion years ago. This stellar explosion, from a star 20 times the size of the Sun, offers a glimpse into the early universe's unique stellar evolution. Part of the JWST Advanced Deep Extragalactic Survey, the event highlights how th...

Astronomers Spot New Cosmic Explosions 100 Times Brighter Than the Sun
Astronomers have discovered a new class of cosmic explosions, known as 'millinovas,' which are 100 times brighter than the Sun. These events, first identified in 2023, were observed in the Large and Small Magellanic Clouds, two satellite galaxies of the Milky Way. The millinovas are thought to occur when white dwarfs feed off a companion star, prod...

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.

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.

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.
