This image shows the Lyman-alpha blob LAB-1. This picture is a composite of two different images taken with the FORS instrument on ESO’s Very Large Telescope - a wider image showing the surrounding galaxies and a much deeper observation of the blob itself at the center made to detect its polarization. The intense Lyman-alpha ultraviolet radiation from LAB-1 appears green after it has been stretched by the expansion of the Universe during its long journey to Earth. These new observations show for the first time that the light from this object is polarized. This means that the giant ‘blob’ must be powered by galaxies embedded within the cloud. Image credit: M. Hayes / ESO.

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

These panels show different components of near-infrared background light detected by the NASA/ ESA Hubble Space Telescope in deep-sky surveys. The one on the upper left is a mosaic of images taken over a ten-year period. When all the stars and galaxies are masked, the background signals can be isolated, as seen in the second and third panels. The one on the upper right reveals ‘intrahalo light’ from rogue stars torn from their host galaxies, and the lower panel captures the signature of the first galaxies formed in the Universe.

Upper image: 3D diagram of the magnetic wormhole, showing how the magnetic field lines (red) leaving a magnet on the right pass through the wormhole. Bottom: in terms of magnetism the wormhole is undetectable, which means that the magnetic field seems to disappear on the right only to reappear on the left in the form of a magnetic monopole.
