Galaxy Cluster IDCS1426

EXTREMELY massive galaxy cluster IDCS 1426.

Located 10 billion light-years from Earth.

Weights about 500 trillion suns.

Recently observed by astronomers in the most detailed study yet.

The light detected is from when the universe was roughly a quarter of its current age. It is the most massive galaxy cluster detected at such an early age.

New data from the Chandra X-ray Observatory confirms the galaxy cluster’s mass and shows that about 90% of the mass of the cluster is in the form of DARK MATTER… AKA a mysterious substance detected so far only through its gravitational pull on normal matter composed of atoms.
