This map of the entire sky shows the location of 739 blazars used in NASA’s Fermi Gamma-ray Space Telescope’s measurement of the extragalactic background light. The background shows the sky as it appears in gamma rays with energies above 10 billion electron volts, constructed from nine years of observations by Fermi’s Large Area Telescope. The plane of our Milky Way Galaxy runs along the middle of the plot. Image credit: NASA / DOE / Fermi LAT Collaboration.

This Hubble image shows NGC 1866, a massive globular cluster located in the constellation Dorado, some 160,000 light-years away. The image was made from separate exposures taken in the visible region of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Five filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble.

This Hubble image shows the Serpens Nebula, a stellar nursery about 1,300 light-years away. Within the nebula, in the upper right of the image, a shadow is created by the protoplanetary disk surrounding HBC 672. While the disk of debris is too tiny to be seen even by Hubble, its shadow is projected upon the cloud in which it was born. In this view, the feature, the Bat Shadow, spans approximately 200 times the diameter of our own Solar System. Image credit: NASA / ESA / STScI.

IC 63 is classified as both a reflection nebula (as it is reflecting the light of a nearby star) and as an emission nebula (as it releases hydrogen-alpha radiation); both effects are caused by the gigantic star Gamma Cassiopeiae; the radiation of this star is also slowly causing the nebula to dissipate.

The positions and reconstructed orbits of 20 high-velocity stars, represented on top of an artistic view of the Milky Way Galaxy. The seven stars shown in red are sprinting away from the Galaxy and could be traveling fast enough to eventually escape its gravity. Surprisingly, the study revealed also thirteen stars, shown in orange, that are racing towards the Milky Way: these could be stars from another galaxy, zooming right through our own.
