Astronomers have found what amounts to a two-faced white dwarf with one side dominated by hydrogen and the other by helium in what could be a transition from one phase to another.
The Zwicky Transient Facility finds a supernova split into multiple images by the gravity of a foreground galaxy in a remarkable example of strong gravitational lensing.
Astronomers have caught normally mild-mannered galaxies in the process of turning into quasars, a faster-than-expected transition that flies in the face of current theory.
A new robotic camera with the ability to capture hundreds of thousands of stars and galaxies in a single shot has taken its first image of the sky, an event astronomers refer to as “first light.”
