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...

Scientists Develop New Approach to Capture Gravitational Wave Memory from Supernovae
A study published in Physical Review Letters highlights new methods to detect the gravitational wave memory effect, a unique phenomenon predicted by Einstein's general relativity. Core-collapse supernovae (massive stellar explosions) generate these low-frequency gravitational waves, offering a rare glimpse into stellar interiors. Despite their weak...

Could a Supernova Threaten Earth’s Survival? Here's What You Need to Know
Supernova explosions have the potential to harm Earth’s atmosphere, particularly the ozone layer. However, no stars close enough to cause damage are currently identified. The risks are low, but gamma-ray bursts, caused by neutron star mergers, may pose an even greater threat in the future.

Astronomers Observe Black Hole That May Have Formed Gently
The conventional wisdom among astronomers is that black holes - those exceptionally dense objects with gravity so powerful that not even light can escape - form in the violent explosion, called a supernova, of a massive dying star.

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...
