Mercury and Venus will star in an early morning meet-up with the moon Friday (July 24). Both planets can be seen low in the east-northeast roughly 45 minutes before sunrise.

Astronomers using NASA's Hubble Space Telescope have gone looking for water vapor in the atmospheres of three planets orbiting stars similar to the Sun -- and have come up nearly dry.

The Hubble Space Telescope has created the most detailed map ever of the star-filled halo encircling Centarus A, the closest giant elliptical galaxy to our Milky Way galaxy. The map reveals a surprising amount of heavy m...

The cloudier an alien planet is, the closer it can get to its star and still remain potentially life-friendly, researchers say. See what it means for life on planets even as hellish as Venus.

NASA's Jet Propulsion Laboratory News and Features: Images of Rosetta's target comet resolve structures as small as 330 feet (100 meters) across.

A new study by NASA and University of California, Irvine, scientists finds more than 75 percent of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. The extent o...

The Canadian military is looking to build a new electro-optical satellite to allow it to continue providing information to the U.S. space surveillance network beyond 2021.

It's commonplace to practice spacewalks underwater, but the latest crew living in an underwater lab plans to introduce a twist: a 10-minute communications delay with mission control.

NASA's Jet Propulsion Laboratory News and Features: A new study finds more than 75 percent of recent water loss from the Colorado River Basin came from underground sources, with grave implications for the West's water su...

NASA's STEREO spacecraft captured imagery of recently discovered Comet Jacques on its nearest approach to the Sun as the object was moving at over 110,000 miles per hour. The comet can be spotted in the pre-dawn hours.

In contrast to NASA and industry claims that work on the Space Launch System is on track, a report by the U.S. Government Accountability Office released July 23 warned that tight schedules and budgets could delay the fir...

NASA has selected Wyle Laboratories, Inc., Houston, to support NASA's flight programs and mission projects, providing support for multiple sustained project management, research and technology development capabilities th...

Astronomers using the NASA/ESA Hubble Space Telescope have mapped the mass within a galaxy cluster more precisely than ever before....

I have a soft spot in my heart for the Hubble Space Telescope. I got my Ph.D. using observations from the venerable observatory (literally signing on to the project two weeks before the 'scope launched into space), then ...

The Sunshield on NASA's James Webb Space Telescope is the largest part of the observatory--five layers of thin membrane that must unfurl reliably in space to precise tolerances. Last week, for the first time, engineers s...

Imagery from the Rosetta mission has been used to create a visualization of periodic comet 67P/Churyumov-Gerasimenko. The probe insert itself into orbit around the comet in the first week of August 2014.

The probe is 125 times smaller than its target, comet 67P/Churyumov-Gerasimenko. Rosetta will come within 62 miles of the surface in the first week of August 2014.
