Dwarf planet Ceres: 'A game changer in the solar system'
In March of 2015, NASA's Dawn mission will arrive at the dwarf planet Ceres, the first of the smaller class of planets to be discovered and the closest to Earth. Ceres, which orbits the Sun in the asteroid ...
High-speed impacts test tech for future missions (w/ Video)
ESA is always thinking ahead to the next generation of space missions, testing new technology far in advance to make concepts a reality.
If we landed on Europa, what would we want to know?
(Phys.org) —Most of what scientists know of Jupiter's moon Europa they have gleaned from a dozen or so close flybys from NASA's Voyager 2 spacecraft in 1979 and NASA's Galileo spacecraft in the mid-to-late ...
British engineers report successful test of space penetrator
Infrared photosynthesis: A potential power source for alien life in sunless places
Photosynthesis—the harvesting of sunlight to produce energy—is the ultimate driver of virtually all life on the surface of our planet. Most photosynthetic creatures rely on optical light, the kind we ...
Cassini finds hints of activity at Saturn moon Dione
(Phys.org) —From a distance, most of the Saturnian moon Dione resembles a bland cueball. Thanks to close-up images of a 500-mile-long (800-kilometer-long) mountain on the moon from NASA's Cassini spacecraft, ...
Where are the best windows into Europa's interior?
(Phys.org) —The surface of Jupiter's moon Europa exposes material churned up from inside the moon and also material resulting from matter and energy coming from above. If you want to learn about the deep ...
Mapping the chemistry needed for life at Europa
(Phys.org) —A new paper led by a NASA researcher shows that hydrogen peroxide is abundant across much of the surface of Jupiter's moon Europa. The authors argue that if the peroxide on the surface of Europa ...
Ancient microbes discovered in bitter-cold Antarctic brine
Where there's water there's life – even in brine beneath 60 feet of Antarctic ice, in permanent darkness and subzero temperatures.
Do a doubletake: Jupiter and Europa
Here's a recent view of Jupiter, with its moon Europa just coming into view from behind the planet, as seen by Efrain Morales of the Jaicoa Observatory in Puerto Rico. Why two images? This is a different ...
Seeking signs of life at the glacier's edge
Microbes living at the edges of Arctic ice sheets could help researchers pinpoint evidence for similar microorganisms that could have evolved on Mars, the Jovian moon Europa, or Saturn's moon Enceladus.
Acidic Europa may eat away at chances for life
The ocean underneath the icy shell of Jupiter's moon Europa could be too acid to support life, due to compounds that may regularly migrate downward from its surface, researchers find.
Scientists see red on NASA cuts of Mars missions
NASA said Monday it's not giving up on Mars, but it'll have to get there later and at a lower price.
In scientific coup, Russians reach Antarctic lake
After more than two decades of drilling in Antarctica, Russian scientists have reached a gigantic freshwater lake hidden under miles of ice for some 20 million years - a pristine body of water that may hold ...
