Astronomers use Gaia data to model Milky Way-Andromeda collision

Science
Feb. 8 (UPI) -- Scientists have long suspected that the Milky Way and Andromeda galaxies are on a collision course, but now, thanks to new data from the European Space Agency's Gaia satellite, researchers finally know how fast and at what angles the two galactic bodies are approaching impact. The Milky Way and Andromeda, along with the smaller Triangulum, are the three biggest galaxies in the Local Group, a collection of more than 54 galaxies -- most of them dwarf galaxies. While scientists think all 54 members are organized by their gravitational influence on one another, the positioning and trajectories of Local Group members isn't well understood. "We needed to explore the galaxies' motions in 3D to uncover how they have grown and evolved, and what creates and influences their features...
Researchers model glaciation on Mercury's poles

Researchers model glaciation on Mercury's poles

Science
Dec. 28 (UPI) -- Mercury's poles are marked by large craters. Icy deposits hide inside. Now, scientists think they know how the ice got there. Researchers at the University of Maine modeled the glaciation process on the planet closest to the sun. Most of Mercury is rather hot. But a few of its polar craters remain in permanent shadow, allowing for temperature low enough to sustain ice deposits. The glaciers are thought to be less than 50 million years old and 165-feet thick in some places. Scientists used data collected by Earth-based radar to characterize the shape, thickness and distribution of Mercury's polar ice. Mercury has no atmosphere that could generate snow or ice deposits. The simulations designed by the University of Maine research team showed a comet impact was the most likel...
