A new study by a team of Cassini mission scientists led by the University of Colorado Boulder have found that microscopic grains of rock detected near Saturn imply hydrothermal activity is taking place within the moon Enceladus.

The University of Colorado Boulder will serve as the Science Operations Center for a NASA mission launching this month to better understand the physical processes of geomagnetic storms, solar flares and other energetic phenomena throughout the universe.

Up for a romantic Valentine’s Day evening? Then head to the University of Colorado Boulder’s Fiske Planetarium to Relativity for Lovers – A Valentine’s Day Among the Stars , for music, film and a talk on the genius of Albert Einstein.

University of Colorado Boulder researchers will update NASA officials next week on a revolutionary space telescope concept selected by the agency for study last June that could provide images up to 1,000 times sharper than the Hubble Space Telescope.

University of Colorado Boulder Distinguished Professor W. Carl Lineberger was honored today by the National Academy of Sciences (NAS) for his extraordinary scientific achievements.

Building on years of collaboration using unmanned aircraft to fly into the storms that create the massive tornadoes that rip across the Midwest, scientists at the University of Colorado Boulder and the University of Nebraska-Lincoln have formed a new research consortium.

Early discoveries by NASA’s newest Mars orbiter are starting to reveal key features about the loss of the planet’s atmosphere to space over time. The findings are among the first returns from NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission, which achieved orbit Sept. 21 and entered its science phase on Nov. 16. The observations reveal a new process by which the solar wind -- an intense stream of hot, high-energy particles blowing off the sun at more than 1 million mph -- can penetrate deep into a planetary atmosphere.

The annual Geminid meteor shower could be a fun show this weekend for Coloradans weather permitting, according to a University of Colorado Boulder astronomer.

When NASA’s napping New Horizon’s spacecraft awakens later this week in preparation for its July 2015 encounter with Pluto, a University of Colorado Boulder student instrument onboard already will have been up for years.

A team led by the University of Colorado Boulder has discovered an invisible shield some 7,200 miles above Earth that blocks so-called “killer electrons,” which whip around the planet at near-light speed and have been known to threaten astronauts, fry satellites and degrade space systems during intense solar storms.
