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 ...

A new study shows how Milky Way chemical tracks emerge from shifting star formation and gas supply, reshaping ideas about the ...

There is growing controversy over recent evidence suggesting that a mysterious force known as dark energy might be changing ...

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 ...

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 ...

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 ...

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.

The largest sample of galaxy groups ever detected has been presented by a team of international astronomers using data from the James Webb Space telescope (JWST) in an area of the sky called COSMOS ...
