Heavy Water with Heavy Implications
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…
How One Pulsar Can Look Like Three: Cosmic-Ray Mirage Halos in the Gamma-Ray Sky
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.
A Planetary Hit-and-Run?
Was Venus involved in a catastrophic hit-and-run? Read this astrobite to find out!
Does the Hubble tension arise from heterogeneity in Type-Ia supernovae?
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.
It’s not you, it’s me. I just need several parsec of space.
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.
UR: Data-Driven Analysis of Galactical Evolution
In the latest of our #UndergradResearch series, discover how to estimate the metallicities of early galaxies using line ratios from JWST with Vidit Bhandari.
