A catalog of over 2,000 exploding white dwarf vampire stars, the largest ever gathered, has provided further evidence that dark energy is weakening.

A catalog of over 2,000 exploding white dwarf vampire stars, the largest ever gathered, has provided further evidence that dark energy is weakening.

Now, new data gathered by looking at the largest supernova dataset ever created suggests that dark energy isn't just a stable part of the universe — it might actually be changing.

Scientists think a gigantic dying star tried to swallow a black hole. It didn't end well for the star, a new study says.

The protocol used to find these young supernova explosions could be used on data from the upcoming Vera C. Rubin Observatory.
