Ostriker is responsible for groundbreaking discoveries that forever changed the way astronomers think about what the universe is made of, including the existence of dark matter.

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 ...

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

In the vast universe, galaxies rotate in ways that don’t make sense if only visible matter is considered. For almost a ...

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