This artist’s impression depicts a Kerr (rapidly spinning) black hole, surrounded by an accretion disc: this thin disc of rotating material consists of the leftovers of a Sun-like star which was ripped apart by the tidal forces of the black hole; shocks in the colliding debris as well as heat generated in accretion led to a burst of light, resembling a supernova explosion.

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.

Astronomers Find Hyper-Starburst Galaxy 12.7 Billion Light-Years Away

This map of dark matter was obtained from data from the KiDS survey, using ESO’s VLT Survey Telescope. It reveals an expansive web of dense (light) and empty (dark) regions. This image is one out of five patches of the sky observed by KiDS. The invisible dark matter is seen rendered in pink, covering an area of sky around 420 times the size of the full Moon. This image reconstruction was made by analyzing the light collected from over 3 million galaxies more than 6 billion light-years away. The observed galaxy images were warped by the gravitational pull of dark matter as the light traveled through the Universe. Some small dark regions, with sharp boundaries, appear in this image. They are the locations of bright stars and other nearby objects that get in the way of the observations of more distant galaxies and are hence masked out in the map as no weak-lensing signal can be measured in these areas.

The location of the FRB 150807. The yellow circle shows the typical location of an FRB. There are thousands of stars and galaxies in this direction. Because FRB 150807 was very bright the astronomers were able to locate it to a small region near the edge of that circle, shown as the pink banana-shaped region in the inset. In this region there are only six detected galaxies. The position of the most likely host galaxy, VHS7, is highlighted on the plot.

This Hubble image shows the dwarf irregular galaxy NGC 4789A. The image also reveals numerous other galaxies, far more distant, that appear as fuzzy shapes spread across the image. The colors in this image have been deliberately exaggerated to emphasize the mix of blue and red stars. The blue stars are bright, hot and massive stars that have formed relatively recently, whereas the red stars are much older. The presence of both tells us that stars have been forming in this galaxy throughout its history. Image credit: NASA / ESA / Hubble / Judy Schmidt, www.geckzilla.com.

Left: this deep Hubble image of the galaxy cluster ZwCl 1715.5+4229 (also known as ZwCl 8193) shows the full extent of the giant galaxy 2MASX 17171926+4226571 and some of its gravitationally lensed background galaxies. The white ‘X’ marks the VLBA radio position, the white ‘+’ marks the Hubble optical position of the giant galaxy’s core, and the white box bounds the zoomed image at right. Right: this shallower zoomed Hubble image of the galaxy cluster reveals the core of the giant galaxy, the smaller galaxy, several cluster galaxies, and extended interaction debris. The Hubble position of the giant galaxy’s core is marked by the white ‘+,’ and optical identification of B3 1715+425 is enclosed by a white circle centered on its Hubble position. Image credit: J.J.
