Aurora Australis as seen from the International Space Station (the link is incorrectly labeled as the borealis which is the phenom in the northern hemisphere, but this photo is actually of the lights as seen over the southern hemisphere!)
This simulation shows the merging of two massive galaxies, sped up to cover 1.5 billion years of time. The merging galaxies are split into two views: a visible-light view is on the left, in which blue shows young stars and red indicates older stars and dust. The view at right shows emission from dust, which is what infrared telescopes like the Herschel Space Observatory see.
Birth Of A Giant Planet: Candidate Protoplanet Spotted Inside Its Stellar Womb This image from the NASA/ESA Hubble Space Telescope shows a visible light view of the outer dust around the young star HD100546. The position of the newly discovered protoplanet is marked with an orange spot. The inner part of this picture is dominated by artifacts from the brilliant central star, which has been digitally subtracted, and the black blobs are not real.
This new view of spiral galaxy IC 342, also known as Caldwell 5, includes data from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. High-energy X-ray data from NuSTAR have been translated to the color magenta, and superimposed on a visible-light view highlighting the galaxy and its star-studded arms.
