A glowing molecular cloud shines today because of a 200-year-old flare let out by our galaxy’s supermassive black hole, scientists say.
Astronomers have reconstructed the Milky Way's merger history, finding that our galaxy has absorbed five large satellite galaxies in the last 12 billion years.
Astronomers have known for decades that our galaxy is warped. Now, they can follow the warp’s rotation as it travels around the galactic center.
Astronomers are using Gaia and the Hubble Space Telescope to make the most precise measure of the Milky Way’s mass to date. The new result puts our galaxy on par with — if not more massive than — Andromeda.
In astronomy news this week: The most luminous quasar known in the cosmos is devouring three galaxy companions, while a newly discovered ghostly satellite of the Milky Way hints at hordes more just waiting to be found.
Using only binoculars, we explore a host of inky dust clouds, the dark nebulae that smudge the Milky Way on late summer nights.
I turned my town into a model of the Milky Way Galaxy for my high school astronomy project.
