Hubble's tale of two exoplanets: Nature vs. nurture

more »
Is it a case of nature versus nurture when it comes to two 'cousin' exoplanets? In a unique experiment, scientists used NASA's Hubble Space Telescope to study two 'hot Jupiter' exoplanets. Because these planets are virtually the same size and temperature, and orbit around nearly identical stars at the same distance, the team hypothesized that their atmospheres should be alike. What they found surprised them.

How one man's shoes help NASA communicate water clarity issues

more »
Scientists make precise measurements of water clarity from satellite data, but the calculations can be hard to explain to the public. Now NASA is adopting a new way -- involving white sneakers -- to communicate water clarity.

Collateral damage from cosmic rays increases cancer risks for Mars astronauts

more »
The cancer risk for a human mission to Mars has effectively doubled following a study predicting a dramatic increase in the disease for astronauts traveling to the red planet or on long-term missions outside the protection of Earth's magnetic field. The new predictive model shows radiation from cosmic rays extends from damaged to otherwise healthy 'bystander' cells.

Study estimates amount of water needed to carve Martian valleys

more »
A new study calculates the amount of water needed to carve the ancient network of valleys on Mars and concludes the planet's surface was once much more watery than previously thought. The study bolsters the idea that Mars had a warmer climate and active hydrologic cycle, with water evaporating from an ancient ocean, returning to the surface as rainfall and eroding the extensive network of valleys.

Highlights of the Summer Sky

more »

What's up in the sky this summer? The featured graphic gives a few highlights for Earth's northern hemisphere. Viewed as a clock face centered at the bottom, early summer sky events fan out toward the left, while late summer events are projected toward the right. Objects relatively close to Earth are illustrated, in general, as nearer to the cartoon figure with the telescope at the bottom center -- although almost everything pictured can be seen without a telescope. Highlights of this summer's sky include that Jupiter will be visible after sunset during June, while Saturn will be visible after sunset during August. A close grouping of the Moon, Venus and the bright star Aldebaran will occur during mid-July. In early August, the Perseids meteor shower peaks. Surely the most famous pending astronomical event occurring this summer, though, will be a total eclipse of the Sun visible over a thin cloud-free swath across the USA on 21 August.
