“A Precocious Black Hole” was uploaded to Flickr

In July 2015, researchers announced the discovery of a black hole that grew much more quickly than its host galaxy. The discovery calls into question previous assumptions on development of galaxies. The black hole was discovered using the Hubble Space Telescope, and detected in the Sloan Digital Sky Survey, by ESA's XMM-Newton and NASA's Chandra. via NASA ift.tt/1jnIyTy

“Hubble Captures a Galactic Waltz” was uploaded to Flickr

This curious galaxy — only known by the seemingly random jumble of letters and numbers 2MASX J16270254+4328340 — has been captured by the NASA/ESA Hubble Space Telescope dancing the crazed dance of a galactic merger. The galaxy has merged with another galaxy leaving a fine mist, made of millions of stars, spewing from it in long trails. via NASA ift.tt/1P8Z0p1

“Northwest Australia From the Space Station's EarthKAM” was uploaded to Flickr

This image of the northwest corner of Australia was snapped by a student on Earth after remotely controlling the Sally Ride EarthKAM aboard the International Space Station. The program allows students to request photographs of specific Earth features, which are taken by a special camera mounted on the station when it passes over these features. via NASA ift.tt/1S95YrK
