Scientists have uncovered the existence of a binary star system close to the black hole near the center of the Milky Way galaxy.

A binary star system would be far more likely to capture the Oort cloud. "Binary systems are far more efficient at capturing objects than are single stars," co-author Avi Loeb said in the statement.

The center of this binary system is a low-mass star—something smaller than our sun—with a brown dwarf orbiting around it.

Astronomers have puzzled over the oddities of the X-ray binary system M33 X-7, but no one could explain all of its features. Now researchers have. They have produced a model of the system's ...

For many years, binary star research has been as neglected as an old Tamagotchi. But now, the Gaia space telescope is leading a resurgence in interest in binary star systems.
