You’d think that supernovae – the death throes of massive stars and among the brightest, most powerful explosions in the universe – would be hard to miss. Yet the number of these blasts observed in ...

Galaxies pass gas—in the case of galaxy NGC 4383, so much so that its gas outflow is 20,000 light-years across and more massive than 50 million Suns. Yet even an outflow of this immensity was ...

Scientists have discovered that bizarre cosmic phenomena known as fast radio bursts are more likely to occur in huge galaxies than in smaller ones, in turn unraveling the secrets of how so-called ...

JWST observations show that early galaxies were chaotic, gas-filled systems rather than stable disks. Researchers from Cambridge studied over 250 galaxies and found most were turbulent, still forming ...

For much of the twentieth century, scientists expected the expanding universe to slow over time. The opposite turned out to be true.

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...

Only a fraction of the size of the Milky Way, these galaxies have thus far been too faint for most telescopes to spot. When you purchase through links on our site, we may earn an affiliate commission.
