Researchers have managed to create a data-based "portrait" of our galaxy blowing two of the largest bubbles ever seen. The bubbles, consisting largely of gamma rays, stretch for tens of thousands of light-years above and below the Milky Way Galaxy.
Two new stars have been discovered in the Milky Way galaxy, and they are the most distant stars ever detected at the edge of our galaxy.
Experts are arguing that the current understanding of galaxy formation is flawed, pointing out that dwarf galaxies orbiting the Milky Way simply do not fit into commonly accepted equations.
Astronomers believe that a high-velocity hydrogen cloud hurtling toward the Milky Way is wrapped in a dark-matter jacket that has allowed it to survive its past galactic collision with the disk of our galaxy.
