Webb observations of the Sextans A galaxy reveal how stars in a metal-poor areas create cosmic dust, offering clues about the ...

Look up at the sky on a clear night, and you’ll see thousands of stars – about 6,000 or so. But that’s only a tiny fraction of all the stars out there. The rest are too far away for us to see them.

Using NASA's James Webb Space Telescope, astronomers have spotted two rare kinds of dust in the dwarf galaxy Sextans A, one ...

But the Big Bang theory predicts that about 5% of the universe's contents should be atoms made of protons, neutrons and electrons. Most of those atoms cannot be found in stars and galaxies – a ...

The very first stars in the universe may have been much smaller than scientists thought — potentially explaining why we can't find evidence of them today. When you purchase through links on our site, ...

Galaxy Y1 shines thanks to dust grains heated by newly-formed stars (circled in this image from the James Webb telescope). Astronomers have uncovered a previously unknown, extreme kind of star factory ...
