Launch of NASA's next Mars rover delayed again by 'contamination concern' on the ground

The launch of NASA's next Mars rover has been delayed to no earlier than July 22 due to a contamination issue with ground support equipment, the space agency said today (June 24). NASA's Mars rover Perseverance was scheduled to launch toward the ...

Heat gave Jupiter's icy moon Europa layers. That may be good news for the search for life.

Jupiter's icy moon Europa experienced enough heat to produce a layered interior and subsurface ocean, scientists say. The finding could help researchers learn about the potential for life on other worlds. Mohit Melwani Daswani, a planetary scientist at ...

Rogue's gallery of dusty star systems reveals exoplanet nurseries

Astronomers this month released the largest collection of sharp, detailed images of debris disks around young stars, showcasing the great variety of shapes and sizes of stellar systems during their prime planet-forming years. Surprisingly, nearly all showed ...

Increased warming in latest generation of climate models likely caused by clouds

As scientists work to determine why some of the latest climate models suggest the future could be warmer than previously thought, a new study indicates the reason is likely related to challenges simulating the formation and evolution of clouds. The new ...
