At least 17 high-inclination Centaurs and two trans-Neptunian objects were captured by the Solar System from the interstellar medium, according to a new...
Clusters of supernovas can cause the birth of scattered, eccentrically orbiting stars in outer halos of Milky Way-mass galaxies, according to new research...
At the center of the Milky Way lurks Sagittarius A*, a supermassive black hole that is four million times the mass of the Sun. Located 26,000 light-years...
Astronomers using data from NASA’s Kepler Space Telescope have discovered an Earth-sized planet in the habitable zone of a low-mass star called Kepler-1649.
