An incredible new image of NASA / ESA's Hubble Space Telescope shows the diverse collection of galaxies in RXC J2211.7-0350, a mbadive cluster of galaxies located about 3.2 billion light-years away in the constellation Aquarius

Clusters of galaxies are the largest objects in the universe related by gravity. Generally, they have a mbad of about one million billion times the mbad of the Sun.
They form over billions of years as smaller groups of galaxies gather slowly.
Their incredible mbad makes clusters of galaxies very useful. test theories in astronomy, such as the theory of general relativity of Einstein
This tells us that objects with mbad deform the fabric of space-time around them; A huge cluster of galaxies like RXC J2211.7-0350 therefore has a huge influence on the space-time that surrounds it, even deforming the light of galaxies further afield to change the apparent shape of a galaxy. galaxy. , creating multiple images, and amplifying the light of the galaxy – a phenomenon called gravitational lens.
Clusters of galaxies are also cosmic laboratories to study the relationship between the distributions of dark matter and visible matter
. % of the matter is invisible, the so-called dark matter.
This image of RXC J2211.7-0350 was taken by the Hubble Advanced Surveying Camera (ACS) and the Wide Field Camera 3 (WFC3) as part of an observation program called "Reionization Lensing Cluster Survey" (RELICS).
RELICS imagined 41 clusters of giant galaxies over 390 Hubble orbits, in order to find the brightest distant galaxies
in more detail with the two current telescopes and the next James Webb Space Telescope. will tell more about our cosmic origins.
