What does this image show? It looks very different from images that typically appear on our web-site, of galaxies and star clusters and exploded stars. It looks vaguely like a swarm of moths but with rectangular shapes that don't really look like wings. It might also pass for abstract art.
The answer is an astronomical one: this is a large mosaic showing Chandra observations from its archive centered on the Virgo Cluster. The rectangles are sets of charge-coupled devices (CCDs) on Chandra, showing X-ray emission from hot gas in the cluster's atmosphere, or around black holes. The rectangles often come in pairs because this is how a common configuration of Chandra CCDs appears on the sky: two square CCDs next to a set of three. The observations are scattered around because they targeted many different galaxies in and around Virgo.
