The domino effect that extreme weather events has on reduction of agricultural production and food inflation is clearer than ever
Astronomers have released a new map of the outermost region of our galaxy. Known as a galactic halo, this area lies outside the swirling spiral arms that make up the Milky Way’s recognizable central disk, and is sparsely populated with stars. Though the halo may appear mostly empty, scientists predict it contains a massive reservoir of dark matter, an invisible material thought to make up the bulk of all mass in the universe. The new map, which appears as part of a paper in Nature, reveals how a small galaxy called the Large Magellanic Cloud—so-named because it is the larger of two dwarf...
Astrophysicists Help Chart Dark Matter's Invisible 'Ocean' A wake of stars, created by a small galaxy set to collide with the Milky Way, is the highlight of a new map of the Milky Way's outer reaches. The observations confirm predictions made by a group of UArizona astronomers whose computer simulations test theories explaining the mysterious nature of dark matter. By Daniel Stolte, University Communications April 21, 2021 Images of the Milky Way and the Large Magellanic Cloud (LMC) are overlaid on a map of the surrounding galactic halo. The smaller structure is a wake created by...
