A new supernova has turned into the most watched phenomenon in the May night sky. The close proximity of the stellar explosion and the vast amount of observations gathered since the discovery promise to advance astronomers' understanding of stellar evolution and could even lead to major advances in supernova forecasting.
Supernovas are powerful explosions in which very massive stars, at least eight times more massive than our sun, die when they use up all the hydrogen fuel in their cores. The discovery of this latest exploding star, known officially as 2023ifx, was a serendipitous one.
