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.

An international team of researchers, including Penn State physicists, leveraged NASA’s James Webb Space Telescope to study nine massive, mature galaxies that ceased forming stars billions of years ...

Nasa is about to launch a space observatory that could help settle some of the biggest mysteries in modern astronomy. The Nancy Grace Roman space telescope will study how the universe began, what it ...

Are dark galaxies hiding in the nearby universe? When we look at the night sky, all the light we see – from planets to stars to nebulae and galaxies – comes from of ordinary matter. Yet astronomers ...

Back in the spring of 2018, a SpaceX Falcon 9 rocket launched into space something that at the time was NASA’s most ambitious project aimed at discovering new alien worlds in solar systems far away.
