The remotely controlled Sally Ride EarthKAM aboard the International Space Station snapped this striking photograph of South Africa on Feb. 9, 2016. The EarthKAM program allows students to request photographs of specific Earth features, which are taken by a special camera mounted on the space station when it passes over those features. To source
NASA’s Cassini spacecraft captured this view of Saturn’s moon Enceladus that shows wrinkled plains that are remarkably youthful in appearance, being generally free of large impact craters. To source
Containing countless galaxies, this parallel field observation is nearly as deep as the Hubble Ultra-Deep Field. When compared to other deep fields, it will help astronomers understand how similar the universe looks in different directions. To source
“Frontier Fields” galaxy cluster MACS J0717, one of the most complex and distorted galaxy clusters known, is the site of a collision between four clusters. It is located about 5.4 billion light years away from Earth. To source
During the afternoon of March 9, 2016, a total solar eclipse was visible in parts of southeast Asia. An eclipse occurs when the moon passes directly between Earth and the sun. The MODIS instrument on NASA’s Aqua satellite captured this image of the total solar eclipse moving across the south Pacific Ocean at 03:05 UTC […]

Although Tethys and Janus both orbit Saturn and are both made of more or less the same materials, they are very different worlds. To source
The distinctive blue bubble appearing to encircle WR 31a is a Wolf–Rayet nebula — an interstellar cloud of dust, hydrogen, helium and other gases. Created when speedy stellar winds interact with the outer layers of hydrogen ejected by Wolf–Rayet stars, these nebulae are frequently ring-shaped or spherical. To source
