Hace 2 días · The first, called the Giant Arc, is actually in the same part of the sky, at the same distance away. When the arc's discovery was announced in 2021, it puzzled astronomers. The Big Ring only deepens the mystery. "Neither of these two ultra-large structures is easy to explain in our current understanding of the universe," Lopez said in January.
Hace 1 día · The first, a giant arc of galaxies, was unveiled in 2022. That structure is 3.3 billion light-years across and appears in the same region of sky at the same distance from Earth as the Big Ring.

Hace 4 días · One of the largest and most massive galaxies in the local universe, it has a large population of globular clusters—about 15,000 compared with the 150–200 orbiting the Milky Way—and a jet of energetic plasma that originates at the core and extends at least 1,500 parsecs (4,900 light-years), traveling at a relativistic speed.
Hace 3 días · NASA's Chandra X-ray space telescope has spotted the supermassive black hole at the heart of our galaxy erupting, proving even quiet black holes like Sagittarius A* need to vent sometimes.
Hace 1 día · The center of the Sun moves around the Solar System barycenter, within a range from 0.1 to 2.2 solar radii. The Sun's motion around the barycenter approximately repeats every 179 years, rotated by about 30° due primarily to the synodic period of Jupiter and Saturn.
