Light is composed of an electromagnetic wave, encoding information about its specific orientation. Learn how observing polarized optical light from one of the most extreme types of events in the universe enables us to study the origin of its light!
Astronomers have observed the abundance of heavy water (D2O) in the V883 Ori disc, providing a crucial insight into the history of water – with some implications for Earth’s water and maybe more…
Cosmic rays don’t always reveal their origins honestly—magnetic fields can bend their paths and create “mirage halos” that look like real gamma-ray sources. New simulations show how a single pulsar can masquerade as three, reshaping how we interpret TeV observations.
Was Venus involved in a catastrophic hit-and-run? Read this astrobite to find out!
How standardizable of a candle are Type-1a supernovae? Learn how differing initial conditions causing a white dwarf to exceed the Chandrasekhar limit and explode might reconcile independent measurements of the Universe’s expansion rate and history.
What does a stellar breakup look like? So dramatic that the stars can’t wait to get away from each other! Today’s authors use physics to search for the one who got away.
