We’ve wondered about Ceres‘ nature and true identity for over two centuries, ever since it was discovered on New Year’s Day, 1801, by Giuseppe Piazzi of Italy. It’s been alternately classified as a planet, asteroid, and more recently as […]

After a seven-year trek, and at the dawn of a new year, NASA’s revolutionary Dawn spacecraft has begun the final approach phase to dwarf planet Ceres for an unprecedented examination of […]
From the location where it came to rest after bounces, the Philae lander of the European Space Agency’s Rosetta mission captured this view of a cliff on the nucleus of comet 67P/Churyumov-Gerasimenko. The feature is called “Perihelion Cliff.” The image is from the lander’s CIVA camera. Credit: ESA/Rosetta/Philae/CIVA

By combining tantalizing clues from several different science instruments, the Rosetta science team is homing in on the location of Europe’s plucky Philae lander’s final landing site after successfully completing history’s first-ever soft landing on a comet, nearly two weeks ago, and discovering organic molecules.

For the first time in human history, a manmade object has touched down on the surface of a comet!
Marking a truly astounding moment, the […]
Philae’s primary landing site from 30 km. Close-up of the region containing Philae’s primary landing site J, which is located on the ‘head’ of Comet 67P/Churyumov–Gerasimenko. The mosaic comprises two images taken by Rosetta’s OSIRIS narrow-angle camera on 14 September 2014 from a distance of about 30 km. The image scale is 0.5 m/pixel. […]
NASA’s Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport (InSight) mission will pierce beneath the Martian surface to study its interior. Insight will hammer the deepest ever hole into the Red Planet to elucidate clues to the Martian core and how Earth-like planets formed. Launch is scheduled for March 2016. Credit: NASA
