Astronomers have found leftover 'zombie star' from supernova shone in the night sky 1,000 years ago

A rare Type Iax supernova event occurred in 1181, likely caused by a collision of two white dwarfs, leaving behind a 'zombie star.'

A new origin story for supernovae after 94 years

Stars can supernova through different pathways; massive stars via core collapse and less massive stars via white dwarf detonation.
Recent research suggests the older model for type Ia supernovae is inadequate, prompting a focus on more complex scenarios.

The Sun Will Destroy the Earth One Day, Right? Maybe Not.

Earth may endure a similar fate as a recently discovered rocky planet around a white dwarf after its star's red giant phase.

James Webb Spots Two Planets Solemnly Orbiting Dead Stars

Astronomers have spotted two gas giant exoplanets orbiting the remains of white dwarf stars, which is unusual due to the extreme forces involved.
The discovery suggests that gas giants could survive their hot stars collapsing and transforming into white dwarfs, but further confirmation is still needed.
