In shaping the Universe, gravity builds a vast cobweb-like structure of filaments tying galaxies and clusters of galaxies together along invisible bridges hundreds of millions of light-years long. This is known as the cosmic web. Image credit: Springel et al. / Max Planck Institute for Astrophysics.

Astronomers Discover Most Luminous, Un-Obscured Star-Forming Galaxy Ever Seen

Sep 28, 2020 by Natali Anderson

A young starburst galaxy named BOSS-EUVLG1 is by far the most luminous, almost un-obscured star-forming galaxy known at any redshift. An artist’s impression...

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