Galaxy Cluster Hidden in Plain View
ScienceDaily (Mar. 6, 2012) — A team of astronomers has discovered the most distant cluster of red galaxies ever observed using FourStar, a new and powerful near-infrared camera on the 6.5m Magellan Baade Telescope. The galaxy cluster is located 10.5 billion light years away in the direction of the constellation Leo. It is made up of 30 galaxies packed closely together, forming the earliest known “galaxy city” in the universe.
NASA’s Chandra Finds Largest Galaxy Cluster in Early Universe;
- El Gordo (ACT-CL J0102-4915)
- Scientists used Chandra and optical telescopes to discover El Gordo some 7 billion light years away and study its properties.
- It is the most massive, the hottest, and gives off more X-rays than known cluster at its distance or beyond.
- El Gordo is actually the site of two galaxy clusters colliding, making it a younger cousin to the well-known Bullet Cluster.
