This artist’s impression shows our Milky Way Galaxy as it may have appeared 6 million years ago during a phase of quasar-like activity. Outside of that bubble, a pervasive ‘fog’ of million-degree gas might account for the galaxy’s missing matter of 130 billion solar masses. Image credit: Mark A. Garlick / CfA.

The ultra-diffuse galaxy Dragonfly 44 and its immediate surroundings. The galaxy consists almost entirely of dark matter, and has a remarkable appearance: it is a low surface brightness, spheroidal object that is peppered with faint, compact sources.

Astronomers using the W. M. Keck Observatory and the Gemini North telescope have found a galaxy that consists almost entirely of dark matter, the mysterious...

Blazars are the most common sources detected by NASA’s Fermi Gamma-ray Space Telescope. As matter falls toward the supermassive black hole at the galaxy’s center, some of it is accelerated outward at nearly the speed of light along jets pointed in opposite directions. When one of the jets happens to be aimed in the direction of Earth, as illustrated here, the galaxy appears especially bright and is classified as a blazar. Image credit: M. Weiss / CfA.

An artist’s concept of the implied distribution of Cepheids (blue) in the Milky Way. With the exception of a small clump in the Galactic center, the central 8,000 light years appear to have very few Cepheids, and hence very few young stars. Image credit: University of Tokyo.

$This is one slice through the map of the large-scale structure of the Universe from the Baryon Oscillation Spectroscopic Survey. Each dot in this picture indicates the position of a galaxy 6 billion years into the past. The image covers about 1/20th of the sky, a slice of the Universe 6 billion light-years wide, 4.5 billion light-years high, and 500 million light-years thick. Color indicates distance from Earth, ranging from yellow on the near side of the slice to purple on the far side. Galaxies are highly clustered, revealing superclusters and voids whose presence is seeded in the first fraction of a second after the Big Bang. This image contains 48,741 galaxies, about 3% of the full survey dataset. Grey patches are small regions without survey data. Image credit: Daniel Eisenstein / SDSS-III Collaboration.$
