RCS2 J2327 explained

RCS2 J2327 (also identified as RCS2 J2327-0204) is an extremely massive galaxy cluster. It is located approximately 6.4 billion light-years away in the constellation of Pisces,^[2] thus making it one of the farthest clusters away from Earth. Recent studies have shown that the galaxy cluster has the mass of two quadrillion suns, making it the second-most-massive galaxy cluster.^[3] The galaxies are known to be distorted by gravitational lensing, which can have the ability to deflect distort, and amplify the light from the objects behind it.^[4] It can also be observed in strong lens, weak lens, and microlens^[5] and has 85% invisible dark matter.^[6]
