Astronomers may be closing in on a long-standing cosmic mystery: why some of the universe's biggest galaxies seem to have far fewer stars than expected. Using NASA- and JAXA-supported XRISM observations of a galaxy called NGC 4151, researchers found ...

I consider this a success already, just from the fact that we're even going to try this."

The Vatican Observatory has operated since 1774. Four nuns cataloged nearly half a million stars for it in the early 20th century. Today it runs a telescope in Arizona.

Astronomers have discovered "one of the most extreme exoplanets" ever found in our universe which orbits a star very like our own Sun.

Don't call it a cluster.

When astronomers talk about a hot Jupiter, they talk about massive gas giants the likes of our own Jupiter, only orbiting their stars at very close range, factors of magnitude closer than our own. They are extreme places, but many of them don't come ...

In astronomers' speak, the term galactic bulge stands for the dense cluster of billions of stars, many of them packed tightly together at the center of spiral and barred spiral galaxies, including our very own Milky Way. But what is a bulge fossil ...

Now, you can join NASA's new Backyard Worlds: Binaries project and help astronomers discover these rare and interesting pairs. As a volunteer, you'll inspect ...

Astronomers have long studied dense collections of stars known as globular clusters scattered throughout the Milky Way. Most appear to have formed in one quick burst early on and then evolved quietly for billions of years. One object in the galaxy's ...
