A spiral galaxy roughly 10 million light-years from Earth is offering astronomers a rare glimpse into the forces that shape ...

The new results are based on the team's analysis of data taken by the Gaia and APOGEE instruments. Gaia is an orbiting space telescope that tracks the precise location, distance, and motion of more ...

Physicists discovered stars near the edge of the Milky Way travel more slowly than those closer to its center -- a surprise suggesting our galaxy's gravitational core may have less dark matter than ...

Astronomers have detected in the stellar halo that represents the Milky Way's outer limits a group of stars more distant from Earth than any known within our own galaxy - almost halfway to a ...

At the center of the Milky Way, an otherwise ordinary star is moving at an extraordinary speed. Every 8.7 years, the faint ...

The distance between the Milky Way and Andromeda in 50 simulations. Just slightly more than half of orbits result in a Milky Way - Andromeda collision within 10 billion years. Sharp features in ...

Astronomers have detected, in the stellar halo that represents the Milky Way’s outer limits, a group of stars more distant from Earth than any known within our own galaxy – almost halfway to a ...
