Betelgeuse’s Companion Star May Have Been Seen at Last
Finally found: using speckle imaging, researchers have spotted what is likely the predicted 1.6-solar-mass companion to the red supergiant Betelgeuse.
See the famous Crab Nebula in a whole new way: researchers have mapped the 3D kinematic structure of the nebula and investigated a jet-like feature emerging from the expanding shell.
A recent study has found that the observed mass–eccentricity relation of warm Jupiters can be explained by dynamical interactions between planets in these systems.
Researchers investigate a planetary nebula in a star cluster in the Andromeda Galaxy — one of just a handful of known extragalactic planetary nebula–open cluster pairs.
Dust Deal with It
Astrobites reports on why we might need a cosmic feather duster to see life on other worlds.
We’re excited to welcome Alexia Kubas and Lucas Brown to the team as AAS Media Fellows for 2026–2027!
A recent study has used spectroscopy from JWST to decipher the source of carbon oxides on the four largest moons of Uranus.
When Bright Spots Go Dark
New modeling tests a common assumption that’s important for interpreting exoplanet spectra: that stars of all spectral types exhibit bright magnetized regions called faculae.
Astrobites reports on how synchrotron emission from thermal electrons could help to explain the behavior of certain tidal disruption events.
