The Spin-Down Rate of AR Sco is Impossible to Know… Right Now
We thought we knew how quickly the white dwarf pulsar in AR Scorpii was spinning down, but a new study tells us we can’t know for sure.
It’s Complicated: Three-Body Interactions Can Affect LIGO’s Binary Black Hole Mergers
Though black holes may start as strangers, interactions between several of them — not just the two component masses — can lead to LIGO-esque mergers.
Sensing a Pulsar’s Sense of Rotation
It should be easy to figure out which way a pulsar is spinning, right? Wrong.
Ancient Trees: A New Kind of Cherenkov Telescope
Astronomy research can be conducted in countless ways, but when’s the last time you chopped into a tree to learn about the cosmos?
Radio Images of a Nearby, Ghostly Globule
A ghostly plasma lens occulting QSR J1819+3845 has been imaged directly at radio wavelengths. What can we learn about this strange interloper? (Image: unrelated observation of solar activity resembling a jack-o’-lantern, courtesy NASA/GSFC/SDO)
