Astrophysicists have broken new ground in ways to observe a star swallowed by a black hole, promising to help paint a clearer picture of this cosmic phenomenon.
Astronomers have discovered a new type of exotic binary star — a rapidly spinning white dwarf star that blast its companion with high energy electrons.
An unusual source of intense radiation is likely powered by a "direct-collapse black hole," a type of object predicted by theorists more than a decade ago.
