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.
Though black holes may start as strangers, interactions between several of them — not just the two component masses — can lead to LIGO-esque mergers.
It should be easy to figure out which way a pulsar is spinning, right? Wrong.
Astronomy research can be conducted in countless ways, but when’s the last time you chopped into a tree to learn about the cosmos?
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)
