"Our scenario describes all the evolutionary phases of the supernova with great precision." An investigation of a cosmic explosion that marked the violent death of a massive star has called into ...

From supermassive black holes to vast stellar nurseries, the distant reaches of space are full of many baffling wonders. Now, scientists have uncovered one of the most perplexing mysteries yet.

Rare cosmic explosions have earned an international award for an astrophysics collaboration led by an Oxford professor.

"Thanks to the high resolution of our new images, we detected a faint structure on the northeast side of this supernova remnant that had not been observed before." The Hubble Space Telescope may have ...

Massive stars, those with initial masses exceeding eight times that of the Sun, undergo complex evolutionary processes that ultimately culminate in spectacular supernova explosions. During their ...
