Between a Nova and a Supernova: The Case of AT 2019abn
What caused this strange red transient that’s too bright to be a nova and too faint to be a typical supernova?
Astronomers search for spacetime ripples from a possible supermassive black hole binary at the heart of the elliptical galaxy 3C 66B.
Astrobites reports on an investigation of a runaway star that may have survived its companion going supernova.
Could a recent collision between the two largest satellites of the Milky Way explain the disrupted state of the Small Magellanic Cloud?
Jupiter’s Atmosphere Holds Steady
Astronomers knew that Jupiter’s upper atmosphere could be strangely warm, but only now do they have global maps showing just where those hot spots are and how long they last.
Thanks to increasingly high-resolution images of the Sun, researchers are catching magnetic reconnection as it happens.
Astrobites reports on a black hole that’s far too massive for its host galaxy, and whether this system could ever reach “normal” proportions.
Using a neural network, researchers have discovered 3,500 candidate strong gravitational lenses in data from the Dark Energy Spectroscopic Instrument.
After the DART spacecraft smashed into Dimorphos, a cloud of ejecta expanded outward. A recent study builds a 3D reconstruction of the ejecta and determines that it’s more complex than previous models considered.
