The Milky Way is a spiral galaxy. More specifically, it is a barred spiral galaxy, meaning that within its central region, there is a bar shape off of which the spirals emanate. About two-thirds of spiral galaxies are barred spirals, and astronomers have thought this difference is just a variance in how density waves cluster stars in a galaxy. But a...

There’s an alien red giant star orbiting in the center of our galaxy. It’s called S0-6 and has chemical fingerprints from its birthplace far outside the Milky Way. This ancient star is spiraling slowly in toward the supermassive black hole Sagittarius A* (Sgr A*) at the heart of the Milky Way. Eventually, it could get drawn into the black hole and destroyed...
