This composite image shows both ALMA and SPHERE/VLT observations of the disk around GW Orionis. The ALMA image (blue) shows the disk’s ringed structure, with the innermost ring (part of which is visible as an oblong dot at the very center of the image) separated from the rest of the disk. The SPHERE observations (orange-red) allowed the astronomers to see for the first time the shadow of this innermost ring on the rest of the disk, which made it possible for them to reconstruct its warped shape.

An artist’s impression of what one of extreme horizontal branch stars, and its giant whitish spot, might look like. The spot is bright, takes up a quarter of the star’s surface and is caused by magnetic fields. As the star rotates, the spot on its surface comes and goes, causing visible changes in brightness.

This ALMA image shows the outcome of a stellar fight: a complex and stunning gas environment surrounding the binary system HD 101584. The colors represent speed, going from blue (gas moving the fastest towards us) to red (gas moving the fastest away from us). Jets, almost along the line of sight, propel the material in blue and red. The stars in the binary are located at the single bright dot at the center of the ring-like structure shown in green, which is moving with the same velocity as the system as a whole along the line of sight. Astronomers believe this ring has its origin in the material ejected as the lower mass star in the binary spiraled towards its red-giant partner.
