This image from the NASA/ESA Hubble Space Telescope shows the reflection nebula NGC 1333 and associated Herbig-Haro objects. The picture was snapped by Hubble’s Advanced Camera for Surveys (ACS). The image was made through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / K.

The galaxy cluster Abell S1063 was observed by the NASA/ESA Hubble Space Telescope as part of the Frontier Fields Program. The huge mass of the cluster -- containing both baryonic matter and dark matter -- acts as cosmic magnification glass and deforms objects behind it. In the past astronomers used this gravitational lensing effect to calculate the distribution of dark matter in galaxy clusters. A more accurate and faster way, however, is to study the intracluster light (visible in blue), which follows the distribution of dark matter. Image credit: NASA / ESA / M. Montes, University of New South Wales.

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 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.
