European Southern Observatory’s Very Large Telescope took photos a rare supernova roughly 300 years after it happened ...

That's because Gaia22ayj is actually a white dwarf feeding on a companion star, with this binary in a rare and short-lived phase of its life (or should that be death).

That's because Gaia22ayj is actually a white dwarf feeding on a companion star, with this binary in a rare and short-lived phase of its life (or should that be death).

However, the vampiric feeding process found in Gaia22ayj isn't something usually associated with white dwarf pulsars. The team eventually concluded that Gaia22ayj is a missing link in the life cycle ...

When the white dwarf has accumulated enough of the other star’s hydrogen, it ignites a thermonuclear explosion, causing the nova. This happens every 80 years or so.

White dwarfs (the dense remnants of stars) are abundant objects throughout the universe and they represent the final stage in the life cycle of most stars. Studying them helps scientists understand ...

To reach these conclusions, they compared the climate of exoplanets at two different stars with similar compositions. One was a hypothetical white dwarf that’s passed through much of its life ...

Another big winner in Cycle 4 is white dwarf science, the study of stars like our sun that have exhausted all their fuel and left just a dense, dead stellar core behind.
