For years, astronomers thought it was the Milky Way’s destiny to collide with its near neighbor the Andromeda galaxy a few billion years from now. But a new simulation finds a 50% chance the impending crunch will end up a near-miss.
Images of the Milky Way, California nebula and Andromeda galaxy are among the winners of the Insight Investment astronomy photographer of the year award.
Scientists were surprised to find that this tenuous, nearly invisible halo of diffuse plasma extends 1.3 million light-years from the Andromeda galaxy and as far as 2 million light-years in some directions.
A new sky survey project, The Zwicky Transient Facility (ZTF), has released its first round of incredible data, results, and images, including this amazing new view of our neighboring Andromeda galaxy.
Trillion Planet Survey is an ambitious experiment, run almost entirely by US students. It uses a suite of telescopes aimed at Andromeda and other galaxies including our own in search for extraterrestrial life.
New research suggests that, contrary to previous estimates, Andromeda galaxy isn’t much bigger than the Milky Way, and is practically our twin.
