The spiral galaxy M61, mistaken for a comet by Charles Messier in 1779, is an anchor tenant of the Virgo galaxy cluster, a beehive of star birth with a massive nuclear cluster and a supermassive 5-million-solar-mass black hole at its core. It is classified as a starburst galaxy with an active galactic nucleus. One of the largest members of the Virgo Cluster, an assembly of more than a thousand galaxies that, in turn, is part of the Virgo Supercluster, M61 is easily visible in amateur instruments despite its 50 million light year distance. But the galaxy’s full glory is revealed in larger instruments, like this shot captured by the European Southern Observatory in 2019.
The world’s largest filled single-dish radio telescope launched at the weekend, and it relies on a piece of West Australian innovation. The 500-metre-wide telescope — known as FAST — uses a data system developed at the International Centre for Radio Astronomy in Perth and the European Southern Observatory to manage the huge amounts of data it generates.
