This image, captured with the Atacama Large Millimetre/submillimetre Array in Chile, features a protoplanetary disc surrounding the young star Elias 2-27, some 450 light years away.

The array has discovered and observed plenty of protoplanetary discs, but this disc is special as it shows two distinct spiral arms, almost like a tiny version of a spiral galaxy.
