For the study, the researchers analyzed 214 of the most massive stars in the Milky Way.

In space, the gravitational pull of massive objects is irresistible to smaller ones. Moons are locked in orbit around planets. Planets, asteroids and comets orbit more massive stars, and stars collect ...

NASA's Pleiades supercomputer has provided fresh insights into the Oort cloud – a vast, theoretical spherical shell of icy objects that surrounds our solar system. For a long time, the Oort cloud's ...

A long-term survey of small, “satellite” galaxies that orbit larger galaxies across the universe offers new insights into our own galaxy, the Milky Way. Since 2012, the Satellites Around Galactic ...

The Milky Way looks serene from our vantage point, a hazy river of light arcing across the night sky. Yet the stars that make up that glow are quietly telling a more dramatic story, one in which our ...

Researchers led by astronomers at the University of Michigan have discovered the smallest and dimmest galaxy to date that's orbiting the Andromeda system, the Milky Way's nearest major galactic ...
