Hubble captures a cornucopia of galaxies
A brief glance at this stunning image captured by the longserving Hubble Space Telescope and you’ll immediately realise that it’s dominated by the bright swirling spiral in the lower left. However, look closely and you’ll see a galaxy cluster behind it. It’s known as SDSS J0333+0651 and it helps astronomers get an understanding of the distant – and therefore early – universe. In particular, allowing researchers to look at star-formation regions up close.
Clusters where galaxies swarm together are quite common, gathered up by gravity to form groups. In fact, our very own Milky Way is a member of the Local Group, which is part of the Virgo Cluster and, in turn, is part of the impressive 100,000-galaxy-strong Laniakea supercluster.
