SDSS001820.5-093939.2 (seen in white) is a small, second-generation star bearing the chemical imprint of one of the universe’s first stars.
This image combines the views from the Hubble Space Telescope and the Keck-II observatory to show a foreground galaxy (a spiral galaxy viewed edge-on) and an almost complete ring: the smeared out image of a star-forming merger beyond.
The Rosetta navigation camera sent back this image of Comet 67P/Churyumov-Gerasimenko on Aug. 23, showing about a quarter of the four-kilometer (2.5-mile) comet.

Five candidate sites were identified on Comet 67P/Churyumov-Gerasimenko for Rosetta’s Philae lander. The approximate locations of the five regions are marked on these OSIRIS narrow-angle camera images taken on 16 August 2014 from a distance of about 100 km.

Post by Alexander Gerst. Or perhaps I should say “eine grosse Aurora!” ESA astronaut Alexander Gerst made this time-lapse of a “massive aurora” as seen from the Space Station on August 24.
This year, the noctilucent cloud season has been especially eventful, and this new timelapse from Swedish astrophotographer Göran Strand shows these “night-shining” clouds covering the entire sky over the course of 2 hours.
This mosaic of images from the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile shows two dramatic star formation regions in the southern Milky Way.
