Three million billion stars 🌟 but who’s counting?! This is a #repost from NASA ( @nasa ) via @PhotoAroundApp Millions AND billions! This enormous galaxy cluster, seen by our Hubble Space Telescope (@NASAHubble), contains the mass of a staggering three million billion suns! Nicknamed “El Gordo” (“the Fat One” in Spanish), it is the largest, hottest and brightest X-ray galaxy ever discovered in the distant Universe. Galaxy clusters are the largest objects in the Universe that are bound together by gravity. They form over billions of years as smaller groups of galaxies slowly come together. In 2012, observations showed that El Gordo is actually composed of two galaxy clusters colliding at millions of kilometers per hour. The formation of galaxy clusters depends heavily on dark matter and dark energy; studying such clusters can therefore help shed light on these elusive phenomena. In 2014, Hubble found that most of El Gordo’s mass is concealed in the form of dark matter. Evidence suggests that El Gordo’s “normal” matter — largely composed of hot gas that is bright in the X-ray wavelength domain — is being torn from the dark matter in the collision. The hot gas is slowing down, while the dark matter is not.

Mayor Hotaru for @galaxyclusters !!! She was so fun to draw and I’m really happy with how she turned out! If there is anything you want me to change, feel free to tell me! Also thank you for letting me draw her!!! I hope you like her!

A galaxy cluster, or cluster of galaxies, is a structure that consists of anywhere from hundreds to thousands of galaxies that are bound together by gravity. They are the largest known gravitationally bound structures in the universe and were believed to be the largest known structures in the universe until the 1980s, when superclusters were discovered. One of the key features of clusters is the intracluster medium (ICM). The ICM consists of heated gas between the galaxies and has a peak temperature between 2–15 keV that is dependent on the total mass of the cluster. Galaxy clusters should not be confused with star clusters, such as open clusters, which are structures of stars within galaxies, or with globular clusters, which typically orbit galaxies. Small aggregates of galaxies are referred to as galaxy group rather than clusters of galaxies. The galaxy groups and clusters can themselves cluster together to form superclusters. source
