Sky gazers in parts of the United States will see two solar eclipses in the next year, beginning with an annular, or "ring of fire," eclipse on Oct. 14. John Keller, director of the Fiske Planetarium, gives his take on what makes these events so exciting—and how you can observe them safely.

Venus is a distinctly unfriendly planet, with crushing atmospheric pressures at the surface and temperatures that hit 900 degrees Fahrenheit. But new observations from scientists at CU Boulder suggest that frequent lightning strikes may not be one of the planet's hazards.

As its name suggests, the newly launched Space Weather Operational Readiness Development (SWORD) center at CU Boulder seeks to offer a little protection for the planet, spurring research into the tumultuous environment several hundred miles above the surface of Earth.

Physicists and engineers at CU Boulder envision infrared astronomy telescopes that may one day span the entire globe—syncing up observations from instruments spread across the continents, or even orbiting Earth, and giving scientists an unprecedented look at phenomena like the birth of new planets.

Scientists will develop “worlds in a box” to investigate the phenomenon of atmospheric escape—how some planets, like Earth, hold onto their atmospheres while others, like Mars, don’t. 

CU’s Heinz Research Group has earned a prestigious NASA award for their research centered on designing lightweight, high-strength materials that could save millions of dollars for spaceflights.

Marking the latest milestone in a new kind of space race, India's Chandrayaan-3 mission touched down safely on the moon. CU Boulder astrophysicist Jack Burns gives his take on why nations and companies are hurrying to parts of the moon that no Apollo craft ever visited.

CU Boulder is leading a major Air Force project to track objects orbiting near the moon, collaborating with researchers at Texas A&M, Georgia Tech and L3Harris Technologies.

A new laboratory for a plasma wind tunnel is taking shape in the aerospace building at CU Boulder. The project is the vision of Assistant Professor Hisham Ali.

An international collaboration, including researchers from CU Boulder, has for the first time uncovered compelling evidence of what scientists call the "gravitational wave background"—enormous undulations in the fabric of space and time.
