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.

This Hubble image shows the Serpens Nebula, a stellar nursery about 1,300 light-years away. Within the nebula, in the upper right of the image, a shadow is created by the protoplanetary disk surrounding HBC 672. While the disk of debris is too tiny to be seen even by Hubble, its shadow is projected upon the cloud in which it was born. In this view, the feature, the Bat Shadow, spans approximately 200 times the diameter of our own Solar System. Image credit: NASA / ESA / STScI.
