A new space mission will seek to better understand a time in the early universe when the first stars lived fast and hard, burning out and going supernova in the span of a few million years.

NASA's OSIRIS-REx spacecraft rendezvoused with the asteroid Bennu in late 2018. Now, researchers think they know what this chunk of space debris is like on the inside.

Scientists at CU Boulder have laid out a roadmap for a decade of scientific research at the moon. Teams from the university will participate in four upcoming or proposed space missions that seek to use the moon as a unique laboratory for peering back to the dawn of the cosmos.

CU Boulder's Jeremy Darling believes that a distant and powerful collapsed star could help scientists to unlock the secrets of dark matter.

In a moment for twos, the Janus mission will launch two identical spacecraft to rendezvous with two asteroid pairs millions of miles from Earth.

NASA's OSIRIS-REx spacecraft observed tiny bits of material jumping off the surface of the asteroid Bennu. A new study tracks where those particles went.

NASA and the National Science Foundation have awarded two CU Boulder space weather scientists more than $5M to lay the groundwork for faster and more robust space weather forecasts.

Future moon astronauts may one day be able to step into an electric-beam shower to clean sticky dust off of their spacesuits and equipment.

In a new study, scientists led by astrophysicist Allison Youngblood set out to view Earth's atmosphere, but with a twist—they wanted to capture what the planet might look like as a far-away world.

See the announcement from NASA Every night on Mars, when the sun sets and temperatures fall to minus 80 degrees Fahrenheit and below, an eerie phenomenon spreads across much of the planet’s sky: a soft glow created by chemical reactions occurring tens of miles above the surface.
