The jets emanating from a famous black hole are cruising along at near light speed, according to new observations.

Astrophysicists are deep in the throes of a process they conduct every 10 years to set scientific priorities for the field; the results could determine which missions fly and which don't.

Mysterious ultra-fast pinpricks of radio energy keep lighting up the night sky and nobody knows why.

A U.S. facility — designed in part to solve the mysteries of dark matter — now officially carries the name of the scientist who concluded that the elusive substance must exist.
