Science@NASA Headline News
You may have noticed that the "look and feel" of Science@NASA stories has changed. There's no cause for alarm. Our core product, simply- and clearly-told stories about NASA science, remains the same. The changes are a sign of progress. Recently, the Science@NASA team joined forces with the Science Mission Directorate at NASA headquarters. Working together, we'll be able to cover a broader range of NASA discoveries and develop "citizen science" opportunities for our readers, while still producing old favorites such as Apollo Chronicles and "looking up" stories about backyard astronomy events. The sky's the limit.

Saturn's giant moon Titan is dotted with hydrocarbon lakes and seas that bear an uncanny resemblance to bodies of water on Earth. Strangely, though, on Titan there are no waves. In this week's story, planetary scientist Alex Hayes discusses the mysterious flatness of Titan's liquid bodies and predicts a sea-change in the near future.

Astronomers working with NASA's Hubble Space Telescope have deduced the actual color of a planet orbiting another star 63 light-years away. The planet is HD 189733b, and its color is cobalt blue. If seen directly, this planet would look like a deep blue dot, reminiscent of Earth's color as seen from space.

Like a comet, the solar system has a tail. NASA's Interstellar Boundary Explorer (IBEX) has for the first time mapped out the structure of this tail, which is shaped like a four-leaf clover.

When Opportunity left Earth in 2003, many observers expected the rover to survive no more than a few months on the hostile surface of Mars. 10 years later, Opportunity is still going strong and could be poised to make its biggest discoveries yet at a place named Solander Point.

Three new papers published in today's issue of Science suggest that Voyager 1, now more than 18 billion kilometers from the sun, is closer to becoming the first human-made object to reach interstellar space.

The count of known asteroids and comets that can come close to Earth continues to mount. The 10,000th near-Earth object, asteroid 2013 MZ5, was detected on June 18, 2013, by the Pan-STARRS-1 telescope.

Arctic permafrost soils contain more accumulated carbon than all the human fossil-fuel emissions since 1850 combined. Warming permafrost, poised to release its own gases into the atmosphere, could be the "sleeping giant" of climate change.
