Astronomers have spotted the most massive known stellar black hole in the Milky Way galaxy after detecting an unusual wobble in space. The so-called "sleeping giant," named Gaia BH3, has a mass that ...

Astronomers have chased hypervelocity stars for more than a century. These rare objects move so fast that the Milky Way ...

The galaxy is expected to be home to billions of free-floating, or "rogue", planets that have no stellar companion. These ...

Scientists measured mass and distance of free floating planet drifting through space without star for first time.

Astronomers have measured the mass and distance of a rogue planet using gravitational microlensing observed from Earth and ...

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 ...

Scientists measure a Saturn-sized rogue planet drifting through the Milky Way using rare Earth and space observations, revealing how planets can be ejected from their original systems.

Our understanding of the galaxy has advanced with every leap in the number of stars. From early observations to more and more advanced space and ground-based telescopes, each milestone has revealed ...

The Milky Way is our home galaxy with a disc of stars that spans more than 100,000 light-years. While the Milky Way is generally always visible from Earth, certain times of year are better for ...
