In a new study, CU Boulder astrophysicist Erica Nelson and her colleagues spotted six "fuzzy dots" of light in images from the James Webb Space Telescope. The candidate galaxies may have existed just 500 to 700 million years after the Big Bang and contain almost as many stars as the Milky Way.

Doug Duncan searched online for something that would allow enthusiasts to safely use their cameras to watch eclipses, but he came up empty-handed. So, he decided he would have to invent something himself.

The universe's carbon atoms complete a journey that spans eons—forming in the hearts of dying stars, then becoming a part of planets and even living organisms. Now, a team led by CU Boulder scientist Jordy Bouwman has uncovered the chemistry behind one tiny, but critical, step in this process.

A new NASA report shows that the University of Colorado Boulder is the top university recipient of NASA astrophysics technology grants.

CU Boulder has been selected as a member of the United States Space Command Academic Engagement Enterprise, a new national program designed to expand collaboration and academic exchanges between universities and Space Command.

Since July 2022, a miniature satellite about the size of a shoebox has been orbiting Earth and monitoring how much solar energy reaches the atmosphere, one of the "most important" Earth science measurements. Now, scientists are finalizing their analysis of the first five months of the testing.

The historic spacecraft soon hit Earth's atmosphere flying at speeds of almost 25,000 mph. CU Boulder aerospace engineer Iain Boyd breaks down what will happen to the capsule, and how NASA will keep it safe on reentry.

A first-of-its-kind sensor, developed by a team at the Laboratory for Atmospheric and Space Physics, will measure sunlight reflecting from Earth with more accuracy than any instrument in space or on the ground.

Ahead of the historic space mission, crew members joined CU Boulder researchers Allie Anderson and Torin Clark to talk about how the eye changes in space, experiencing "space motion sickness" and more.

NASA’s Orion spacecraft blasted off this morning from Florida in the first stage of its 25-day journey to circle the moon and return to Earth. Two CU Boulder scientists talk about what lies in store for the space agency’s ambitious Artemis Program.
