This image from the ALMA telescope shows the star system HD101584 and the complex gas clouds surrounding the binary pair. The clouds are the result of two stars that shared a common outer layer in the last moments of their lives. Credit: ALMA (ESO/NAOJ/NRAO), Olofsson et al., : Robert Cumming.

This figure shows a stage in the merger of two galaxies that creates a single galaxy with two supermassive black holes at the center and surrounded by disks of hot gas. The black holes orbit each other for hundreds of millions of years as they merge to form a single supermassive black hole that sends out powerful gravitational waves. Credit: NASA/CXC/A.Hobart
