But where is the unseen mass that Fritz Zwicky proposed to keep galaxies in the Coma Cluster
from flying apart?
In spring 2014, researchers pointed Dragonfly at the well-studied Coma cluster
, a conglomeration of thousands of galaxies.
Eight-hundred fifty-four "ultra-dark galaxies" in the Coma Cluster
have been discovered by a team of researchers from Stony Brook (N.
com/topic/Coma-cluster) Coma cluster
, according to one of the group's lead researchers, astrophysicist Kyoung-Soo Lee.
ISLAMABAD -- After analysing data obtained with the Subaru Telescope, astronomers have discovered 854 "ultra dark galaxies" filled with mysterious dark matter in the Coma Cluster
, one of the richest cluster of galaxies containing thousands of systems.
The Coma cluster
, a non-cool cluster, is filled with gas at a scorching 100 million degrees Celsius.
It shares an evolutionary path with some of the most massive clusters we see today, including the Coma Cluster
and the recently discovered El Gordo Cluster," said team member Mark Brodwin of the University of Missouri-Kansas City.
In addition, 18 papers reported research results in such areas as the dark matter halo shape of NGC 2976 via stellar kinematics, investigating inner disk lifetimes in Ophiuchus, barred galaxies in the Coma Cluster
, and detailed abundances in a metal-poor stellar stream.
Other LJMU astronomers are currently leading the Hubble Space Telescope survey of the COMA cluster
, located some 280 million light years from Earth.
The Coma Cluster
is merely stellar flotsam compared with what lurks at greater depths in the vast ocean of the cosmos.
So galaxies in the Coma Cluster
appear to us as they looked seven hundred million years ago, about the time the first jellyfish - its own roseate nucleus of cells and spinning arms - was developing on earth,
