This image from ESO’s VISTA telescope shows the central part of the Milky Way. While normally hidden behind obscuring dust, the infrared capabilities of the telescope allow astronomers to study stars close to the Galactic center. Within this field of view astronomers detected several RR Lyrae stars. Image credit: ESO / VVV Survey / D. Minniti et al.

Planets form from epic collisions between asteroids and even bigger bodies, called protoplanets. Sometimes the colliding bodies are ground to dust, and sometimes they stick together to ultimately form larger, mature planets. This artist’s conception shows one such smash-up.

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.
