Astrophysics

ESA's Gaia mission launched successfully on a Soyuz-Fregat rocket from Kourour, French Guiana at 09:12 UT on 19 December 2013. The mission is designed to measure the positions and velocity of roughly 1,000,000,000 stars as well as determine their temperature, composition, and other properties. More...

NASA's Wide-field Infrared Survey Explorer (WISE) satellite has released data from the first 57% of the sky surveyed during the mission. The satellite went into hibernation in early February 2011, but its discoveries include 20 comets, more than 33,000 asteroids between Mars and Jupiter, and 133 near-Earth objects. More...

A study of Ganymede's aurorae using the Hubble Space Telecope has provided the best evidence yet for a subsurface saltwater ocean on Jupiter's largest moon, possibly as thick as 100 km, below a 150 km thick crust. More...

The Dawn spacecraft successfully entered orbit around the largest asteroid, Ceres, at 12:29 UT (7:39 a.m. EST) Friday, 06 March. It has already returned many new images of Ceres including one showing two bright spots in one crater. More...

The Japanese Space Agency (JAXA) Hayabusa 2 sample return mission to asteroid 1999 JU3 was launched successfully on 03 Dec. 2014 at 04:22:04 UT (11:22 p.m. 02 Dec. EST). The spacecraft will reach the asteroid in June 2018 and the sample will be returned to Earth in December 2020. Also launched with Hayabusa 2 was the PROCYON asteroid flyby small satellite.
