If there are two supernovae per millennium in your average galaxy and there are at most 200 billion galaxies in the universe, every second, around 13 stars go supernova.

“We’re essentially opening a new window on the transient universe” said Matthew Siebert of the Space Telescope Science Institute, capturing the awe that swept through the astrophysics ...

The first generation of stars in the universe could have produced significant amounts of water upon their deaths, just 100 million to 200 million years after the Big Bang.

Although our universe is mostly normal matter, antimatter isn’t so hard to create — supernovae, black holes, and even bananas can make it.

New data involving millions of galaxies and luminous galactic cores is providing fresh evidence that the enigmatic and invisible cosmic force called dark energy - responsible for the universe's ...

What are Type Ia supernovae? The majority of the universe’s supernovae are the explosive deaths of massive stars. One important supernova variety comes from an unassuming source– white dwarfs.

Estimates based on the spacing of fluctuations in the universe’s oldest light differ by about 10% from those based on the distance to supernovae in distant galaxies.
