Astronomers Discover First Ice Giant Exoplanet Candidate In Long-Period Orbit

This artist’s concept shows Kepler-421b, a Uranus-sized transiting exoplanet with the longest known year, circling its star once every 704 days. Kepler-421b orbits an orange, K-type star that is cooler and dimmer than our Sun and is located about 1,000 light-years from Earth in the constellation Lyra.

Hubble Discovers Two Potential KBO Targets for NASA's New Horizons Spacecraft, Follows Up With Additional Search

Discovery images of the two Kuiper Belt Objects named 1110113Y and 0720090F respectively, taken with NASA’s Hubble Space Telescope. The image at left shows the first KBO at an estimated distance of approximately 4 billion miles from Earth. Its position noticeably shifts between exposures taken approximately 10 minutes apart. The image at right shows [...]

ESA's Rosetta Spacecraft Closes In on Comet 67P/Churyumov-Gerasimenko, Detects Huge Amounts of Water Outgassing

ESA’s Rosetta spacecraft, which is presently en route to the comet 67P/Churyumov–Gerasimenko, has detected that the comet’s nucleus outgasses huge amounts of water vapor each second, despite its current distance of approximately 3.7 Astronomical Units from the Sun. Image Credit: ESA

NASA's Cassini Spacecraft Conducts Important Science During Several Flybys of Titan, Probes Its Enigmatic Seas

A view of the night side of Titan taken by the Cassini spacecraft, which captures the blue halo caused by a haze layer that hovers high in the moon’s atmosphere. The spacecraft conducted several flybys of the moon in recent months, during which it beamed a series of radio waves through its atmosphere, in [...]

Flight Test for Next-Generation Mars Supersonic Decelerator Prototype Rescheduled for June 28

The saucer-shaped LDSD test vehicle is seen here in the Missile Assembly Building at the U.S. Navy’s Pacific Missile Range Facility in Kaua‘i, Hawaii. The vehicle, part of NASA’s Low Density Supersonic Decelerator project, will test an inflatable decelerator and a parachute at high altitudes and speeds over the Pacific Missile Range this summer.
