Astronomers find an ancient black hole speeding through the Sun’s Galactic neighborhood, devouring a small companion star as the pair travels in an eccentric orbit looping to the outer reaches of our Milky Way Galaxy.
An international team of astronomers has discovered the first gravitational lens in which the single image of a very distant galaxy has been split into six different images.
Astronomers have made the first radio-telescope images of a powerful coronal mass ejection on the Sun, giving them a long-sought glimpse of hitherto unseen aspects of these potentially dangerous events.
Astronomers have used the National Science Foundation’s Very Long Baseline Array radio telescope to do a very detailed map of the magnetic field within a star-forming cloud.
Astronomers using the National Science Foundation’s 140-foot radio telescope at the National Radio Astronomy Observatory in Green Bank, W.Va., have discovered a highly unusual, massive interstellar cloud that appears poised to begin a burst of star formation.
A team of observers used a gamma-ray burst as a powerful tool to unveil the nature of the galaxy in which it occurred, more than 7 billion light-years away.
