Way back in 2014, researchers had discovered some 47 similar dark galaxies which had then surprised the researchers.
Dr. Jin Koda, a key investigator of the study said: Not only these galaxies appear very diffuse.
He added: But they are very likely enveloped by something very massive.
These observations suggested that thestellar populations have lasted for a long timewithin the cluster.
Subaru Telescope had made its first light observations way back in1999,some 16 years ago.
The latest detection of 854 dark galaxies was possible only due to the vast archived Subaru data.
