everywhere else. Without it, the galaxy as we know it simply would not hold together. The Galactic Center Environment Sagittarius A* Evidence for a Supermassive Black Hole Deep in the middle of the Milky Way sits Sagittarius A*, a small but powerful...

A newly discovered star orbiting Sagittarius A* could provide astronomers with a rare, groundbreaking way to measure the Milky Way’s central black hole. Astronomers have uncovered a celestial speedster named S301, a star hurtling through the extreme...

supermassive black hole, overturning long‑standing theories. New infrared data show that several dusty bodies orbiting Sagittarius A*, the Milky Way’s central supermassive black hole, are persisting in a region where tidal forces were expected to shred...

Astronomers have discovered S301, a star orbiting Sagittarius A* at 8.5% the speed of light, offering a unique new way to measure the black hole’s spin. Astronomers have identified a new stellar resident in the immediate vicinity of the Milky Way’s...

A new study suggests our galaxy’s black hole, Sagittarius A*, may accelerate particles to extreme PeV energies by tapping into its own rotational power. New theoretical research suggests that the supermassive black hole at the center of our galaxy,...
