Casting Doubt on a Nearby Black Hole
Scientists recently announced the discovery of the nearest black hole to Earth — but there may be a different explanation for this stellar puzzle.

When a star like our Sun evolves into a red giant, what happens to its planets? A new study explores this apocalyptic future.
Astrobites sheds some light on the inner workings of an ultra-red, massive cluster core spotted at high redshift.
How can we tell how much energy is leaking out of active regions on the Sun?
Recent observations from ALMA are providing a new look at the presence — and absence — of turbulence in planet-forming disks.
The Voyager probes, launched more than 40 years ago, are still providing new insights.
Astrobites reports on a machine-learning approach to explore light emitted from the gas distributed throughout galaxy clusters.
Could a pair of faint signals correspond to the first collision we’ve detected of a black hole with a neutron star?
Starspots on M dwarfs could be mistaken for planets. How do we distinguish the two?
The size of a supermassive black hole seems to track with the size of its host galaxy. But is this a statistical fluke, or is there a physical reason for the connection?
M dwarfs are known to be highly active when they’re young, which is bad for habitability. But what about old M dwarfs? Astrobites reports.
This dramatic simulation shows how the escape of blobs of plasma from a magnetar could produce fast radio bursts.
