An artist’s rendering of the mysterious object, which has a mass about 2.6 times that of the sun and was consumed by a black hole some 23 times the mass of the sun. Astronomers say it's less massive than any known black hole and more massive than any known collapsed star, called a neutron star.

Distant Black Hole Collides With a Mysterious Object

Scientists detect what is either the heaviest known neutron star or the least massive black hole ever recorded

A near-infrared, color image taken by NASA's Cassini spacecraft shows the sun glinting off of north polar seas on Saturn's largest moon, Titan. Similar glints were spotted from Earth in 2000 at Titan's equator but Cassini found no evidence of liquid there.
