Selections from 2019: Discovery of an Intermediate-Mass Black Hole
Unusual motions in a cloud of gas provide evidence for a 30,000 solar-mass black hole drifting near our galaxy’s center.

The collective gravity of a disk of distant, cold objects in our solar system could provide a natural alternative to Planet Nine.
A recent study explores how absorption in Venus’s atmosphere influences the planet’s weather on long timescales.
The discovery of an extremely distant supermassive black hole can teach us about conditions in the early universe.
What does the presence of carbon monoxide in an exoplanet’s atmosphere tell us in the context of the search for life beyond Earth?
Interstellar asteroid ‘Oumuamua may be part of a larger population of bodies with unusual structure.
Evidence has been found for a giant planet orbiting around a binary that consists of one dead and one living star.
Some astrophysical sources should produce both neutrinos and gravitational waves. What have we learned looking for this simultaneous signal?
Noticed a change in AAS journal keywords? Here’s why we’re using a new system, and what it could do for the field.
One of the fastest spinning radio pulsars known has now been detected to pulse in gamma rays, too.
How a star spins can significantly impact its evolution — yet stellar rotation remains poorly understood. Astrobites reports on what we can learn by studying stellar pulsations.
To study the atmosphere of an exoplanet, it turns out we need to have a solid handle on its mass.
