NASA just released this breath-taking picture of the Orbiter Endeavour, taken on May 28th, just a day before it undocked from the International Space Station and began to make its way to Earth.
That is Mercury as seen by the MESSENGER spacecraft in 2008, as it flew by the planet for the first time. It would do so again before finally entering orbit in March 2011. But as it left the smallest planet, it snapped a series of wide angle and high-resolution images.
On April 24th, 1990, the Space Shuttle Discovery roared into space, carrying HST into orbit and into history. In honor of this anniversary, astronomers have released a new image of the interacting galaxies Arp 273, and it’s a beaut.
This amazing image takes all 1,235 of the candidate planets spotted by NASA's Kepler telescope, and then shows them in orbit around their stars. And all of this is still just the tiniest fraction of the entire Milky Way.
