Astrum. The Star Explosion That Outshone the Entire Galaxy. Posted: April 29, 2025 | Last updated: April 29, 2025. In October 2022, the universe unleashed its most powerful recorded explosion—2 ...

Astronomers discovered a star explosion, called a supernova, in the Pinwheel galaxy, also known as "M101." The dramatic cosmic event is visible with a telescope. Here's how to see it.

A huge explosion of cosmic gas has been spotted at the heart of a far-off galaxy. This enormous outburst, known as a "gas outflow," is around 20,000 light-years across, about one-fifth of the ...

O’Connor and his colleagues recently traced most of those swift gamma bursts — including the 2015 explosion, dubbed GRB 151229A — to a previously-unnoticed group of very distant galaxies.

Hubble was used to study this galaxy with a particular focus on the supernova it hosted. “Two different teams of astronomers used Hubble’s Wide Field Camera 3 to observe UGC 12295 and sift ...

The newfound magnetar, a dense relic of a once-bright star with a remarkably strong magnetic field, resides in the galaxy M82 (dubbed the Cigar Galaxy), roughly 12 million light-years from Earth.

Researchers have used machine learning to dramatically speed up the processing time when simulating galaxy evolution coupled with supernova explosion. This approach could help us understand the ...
