AUSTIN, Texas — The largest cluster of galaxies seen yet in the early universe, a giant that astronomers have dubbed "El Gordo," could one day reveal secrets about the invisible dark matter that fills the universe, researchers said.
El Gordo — which means "the fat one" in Spanish — is officially known as ACT-CL J0102-4915 and "is located more than 7 billion light-years from Earth, at a time when the universe was half its current age," study co-author John Patrick Hughes at Rutgers University told SPACE.com. The universe is about 13.7 billion years old. The monster galaxy cluster has mass about 2 quadrillion (that's 2 followed by 15 zeroes) times that of the sun, making it "the most massive known cluster in the distant universe.
" A galaxy cluster behemoth Galaxy clusters form through mergers of smaller groups of galaxies. Dark energy seems to make up 73 percent of all the mass and energy in the universe, and is driving the accelerating expansion of the universe. El Gordo, a hot galaxy group. We Choose the Moon.

Ancient astronomers observed points of light that appeared to move among the stars. They called these objects "planets," meaning wanderers, and named them after Roman deities—Jupiter, king of the gods; Mars, the god of war; Mercury, messenger of the gods; Venus, the goddes of love and beauty, and Saturn, father of Jupiter and god of agriculture. The stargazers also observed comets with sparkling tails, and meteors or shooting stars apparently falling from the sky. Since the invention of the telescope, three more planets have been discovered in our solar system: Uranus (1781), Neptune (1846), and, now downgraded to a dwarf planet, Pluto (1930). The four planets closest to the sun—Mercury, Venus, Earth, and Mars—are called the terrestrial planets because they have solid rocky surfaces. Nearly every planet—and some of the moons—has an atmosphere. Moons, Rings, and Magnetospheres. The Scale of the Universe. Hubble Heritage Gallery of Images.
