Astronomers say they have traced a mysterious pulsing in the Milky Way to a surprising source: a dead star locked in a dance with another star.

Astronomers have figured out where a stream of long radio bursts is coming from, and its origin is unprecedented. Rather than coming from the typical neutron star—the core of a star that has exploded and can no longer undergo nuclear fusion—the pulses are emitted by a pair of stars locked in a cosmic dance with one another.

An international team of astronomers led by scientists from the Netherlands has shown that a white dwarf and a red dwarf orbiting each other every two hours are emitting radio pulses. Thanks to observations with several telescopes,

Astronomers have identified a quartet of small rocky planets orbiting Barnard's star - one of our closest stellar neighbors - though they concluded that all of them are too hot to harbor life, much like our solar system's innermost planet Mercury.

Exciting new research suggests there are four miniature planets orbiting Barnard’s Star, each thought to be just 20 to 30% the mass of Earth.
