Neptune-mass planets like the one shown in this artist’s rendering may be the most common in the icy regions of planetary systems; beyond a certain distance from a young star, water and other substances remain frozen, leading to an abundant population of icy objects that can collide and form the cores of new planets; in the foreground, an icy body left over from this period drifts past the planet.

ALMA image of the protoplanetary disk surrounding the young star HD 163296 as seen in dust. New observations suggested that two planets are in orbit around the star. These planets, which are not yet fully formed, revealed themselves by the dual imprint they left in both the dust and the gas portions of the star’s protoplanetary disk.

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.

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.
