Intense storms batter Saturn’s largest moon, scientists report
more »
Titan, the largest of Saturn's more than 60 moons, has surprisingly intense rainstorms, according to research by a team of UCLA planetary scientists and geologists. Although the storms are relatively rare -- they occur less than once per Titan year, which is 29 and a half Earth years -- they occur much more frequently than the scientists expected.

A better understanding of space, via helicopter
more »
An algorithm that helps engineers design better helicopters may help astronomers more precisely envision the formation of planets and galaxies. Researchers have created a new model for understanding how black holes, planets, and galaxies emerge from the vortex-rich environments of space.

Satellites map photosynthesis at high resolution
more »
Life on Earth is impossible without photosynthesis. It provides food and oxygen to all higher life forms and plays an important role in the climate system, since this process regulates the uptake of carbon dioxide from the Earth's atmosphere and its fixation in biomass. However, quantification of photosynthesis at the ecosystem-to-global scale remains uncertain. Now an international team of scientists have made a major step forward.

Devourer of planets? Astronomers dub star 'Kronos'
more »
'Kronos' is enhanced in metals and other rock-forming elements but not in volatiles, prompting a team of researchers to conclude that it absorbed as much as 15 Earth masses worth of rocky planets. Its twin, 'Krios,' does not show this unusual pattern of enhancement.

Reconstructing Cassini's plunge into Saturn
more »
As NASA's Cassini spacecraft made its fateful dive into the upper atmosphere of Saturn on Sept. 15, the spacecraft was live-streaming data from eight of its science instruments, along with readings from a variety of engineering systems. While analysis of science data from the final plunge will take some time, Cassini engineers already have a pretty clear understanding of how the spacecraft itself behaved as it went in.

The moon once had an atmosphere
more »
A new study shows that an atmosphere was produced around the ancient Moon, 3 to 4 billion years ago, when intense volcanic eruptions spewed gases above the surface faster than they could escape to space.
