An Update on Fast Radio Bursts: New Discovery in Our Own Galaxy
Have we recently spotted the first equivalent of a fast radio burst located within our own galaxy?
History as Told by a Merger Background
How does the rate of binary black hole mergers change with time? The gravitational waves produced by undistinguished individual mergers might be able to help.
LIGO/Virgo’s Newest Merger Defies Mass Expectations
The two black holes that merged in GW190521 are the most massive we’ve observed yet, and this has major astrophysical implications.
A Stellar Pinwheel at a New Wavelength
A recent study explores a spiral pattern spotted around an unexpected source.

Will Radio Bursts Reveal Hidden Baryons?
A recent study has used bursts of radio emission to probe whether the outskirts of our galaxy are hiding vast quantities of “missing” baryonic matter.
Getting Deeper into the Main Sequence with Gaia
Combining Gaia data with the HR diagram — a plot of star colors and brightnesses — can tell us new things about the lives of stars.
The Impact of Land on an Ocean World’s Habitability
A new study explores how oceans and continents affect whether a habitable-zone planet can actually support life.
When Dark Matter Gets Fuzzy
What model of dark matter best describes our universe? A new study uses a unique region in our own galaxy to constrain one particular model: that of fuzzy dark matter.
