NASA has released a batch of images from the Chandra X-ray Observatory that they have dubbed "razzle-dazzle across space." ...

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 ...

For decades, the prevailing view has been that dark energy causes the universe’s expansion to accelerate indefinitely, potentially ending in a scenario known as the “Big Rip,” in which galaxies, stars ...

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 ...

A mysterious force called Dark Energy might be changing, in a way that challenges our current understanding of the nature of ...

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 ...

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

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 ...

The James Webb Space Telescope caught a glimpse of these violent bundles of gas and stars. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The ...

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 ...

While nearly all massive galaxies possess central black holes, the presence of such black holes in dwarf galaxies remains an open question, with previous estimates identifying them in only 0.5% of ...
