Galaxies like our Milky Way are mysteriously hard to come by in our cosmic backyard. New supercomputer simulations have helped astronomers finally answer why. The Milky Way sits within a galaxy cluster on the Supergalactic Plane — a billion light-year-wide sheet, or “supercluster,” upon which large galaxy clusters are pinned. But other spiral galaxies are … Read more
Astronomers have discovered hundreds of strange, stringlike structures at the center of our galaxy, possibly tracing the violent path of an ancient black hole eruption. According to new research published June 2 in The Astrophysical Journal Letters, each of these previously unknown “filaments” measures between 5 and 10 light-years in length — thousands of times … Read more
For the first time, scientists have discovered a double-star system that is doomed to explode in a fiery “kilonova,” a precious-metal-creating blast caused by the merger of two stellar corpses. The kilonova — which will send gold, silver, platinum and other new heavy elements careening into space — won’t happen for millions of years. But … Read more
The exact origins of the Milky Way are shrouded in mystery. But astronomers believe that our home galaxy started out more than 13 billion years ago, and that it was much smaller than its present-day size. How did it grow so much to reach its current size? For that, we can likely thank eons of … Read more
Two of the strangest, most colossal structures in the Milky Way may have formed in a 100,000-year-long explosion at our galaxy’s center, new research suggests. Those structures — named the Fermi bubbles and eROSITA bubbles after the respective telescopes that discovered them — straddle the Milky Way’s center in an enormous hourglass shape, with one … Read more
