The distorted galaxy in the simulation (main image) results from a collision and merger between two galaxies. Astronomers think such a merger could be the reason why SPT0346-52 is having such a boom of stellar construction. Once the two galaxies collide, gas near the center of the merged galaxy (shown as the bright region in the center of the simulation) is compressed, producing a burst of new stars. The composite inset shows X-ray data from Chandra (blue), short wavelength infrared data from Hubble (green), infrared light from Spitzer (red) at longer wavelengths, and infrared data from ALMA (magenta) at even longer wavelengths. There is no blue at the center of the image, showing that Chandra did not detect any X-rays that could have signaled the presence of a growing black hole.

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

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.
