The most distant and earliest "dead" massive galaxy ever seen shows some galaxies lived fast and died young shortly after the ...

Galaxies may not be as simple as "young and blue" or "old and red." A new idea from astrophysicist Charles Steinhardt proposes a third type: red star-forming galaxies that break the mold. These galaxi ...

To celebrate Hubble's 35th anniversary, ESA/Hubble released a breathtaking new image of the star-forming region NGC 346 in ...

The universe doesn't come with an instruction manual—but if it did, University of Missouri Assistant Professor Charles ...

"We were surprised by the streams of light that were visible near the center of the galaxies, as nothing similar has been ...

Researchers mapped a far-infrared landscape brimming with nearly 2,000 galaxies. There may be "hidden galaxies" lurking just ...

Astronomers have peered back in time to find what looks like a population of "hidden" galaxies that could hold the key to ...

Astronomer Charles Steinhardt said most stars we see "might have formed under different conditions than we previously believed." ...

For a long time, scientists thought that only actively star-forming galaxies should be observed in the very early Universe.

The cluster, full of more than 2,500 newborn stars that blaze blue in the Hubble image, is in a galaxy with far fewer heavy chemical substances than the Milky Way. It's mostly made of hydrogen and ...
