Astronomers have detected a massive, sprawling, churning galaxy cluster that formed only 3.8 billion years after the Big Bang.

Formed only 3.8 billion years after the Big Bang it is 10 billion light yrs from Earth and potentially comprising thousands of individual galaxies, the megastructure is about 250 trillion times more massive than the sun, or 1,000 times more massive than the Milky Way galaxy. The cluster, IDCS J1426.5+3508 (or IDCS 1426), is the most massive cluster of galaxies yet discovered in the first 4 billion years after the Big Bang.
