This spectacular scene was captured by Hubble’s Advanced Camera for Surveys and Wide-Field Camera 3 as part of an observing programme called RELICS. These smeared shapes are in fact galaxies, their light heavily distorted by the gravitational field of Abell 2537. Hubble has probed star clusters of all sizes and uses spectroscopy to determine the detailed chemistry in star cluster members. Abell 2537 is a particularly efficient lens, as demonstrated by the stretched stripes and streaking arcs visible in the frame.

T his phenomenon can produce a magnifying effect, allowing us to see objects that lie behind the cluster and are thus otherwise unobservable from Earth. Abell 2537’s gravity warps the very structure of its environment ( spacetime ), causing light to travel along distorted paths through space. There is so much matter stuffed into a cluster like Abell 2537 that its gravity has visible effects on its surroundings. Ĭlusters are useful in probing mysterious cosmic phenomena like dark matter and dark energy, the latter of which is thought to define the geometry of the entire Universe. These groupings of galaxies are colossal - they are the largest structures in the Universe to be held together by their own gravity. Its light took 13.4 billion years to reach Earth. Hubble also holds the cosmic distance record for a galaxy. Its an enormous blue star nicknamed Icarus.' Earendel should not be confused with the oldest known star, nicknamed Methuselah, discovered by Hubble in 2013. Galaxy clusters such as this one contain thousands of galaxies of all ages, shapes and sizes, together totalling a mass thousands of times greater than that of the Milky Way. The previous record holders light took 9 billion years to reach Earth. This picturesque view from the NASA/ESA Hubble Space Telescope peers into the distant Universe to reveal a galaxy cluster called Abell 2537.
