The powerful gravity of a galaxy embedded in a massive cluster of galaxies in this Hubble Space Telescope photo is producing multiple images of a single distant supernova far behind it. Both the ...

One of the most stubborn issues in cosmology today concerns the universe's rate of expansion. Scientists know it's expanding, ...

This supernova is one for the record books. A mammoth star explosion known as SN2016aps, which occurred in a galaxy about 3.6 billion light-years from Earth, is the brightest supernova ever seen, a ...

A distant stellar explosion has offered astronomers a rare natural experiment, one that turns gravity into a powerful optical tool. The object, known as SN 2025wny, appears not once but four times in ...

A new look at the debris from an exploded star in our galaxy has astronomers re-examining when the supernova actually happened. Recent observations of the supernova remnant called G11.2-0.3 with ...
