JWST, now a 20-month-old space toddler, is still serving up astronomical “firsts” nearly two years since its launch. Recently, it snapped the first-ever direct picture of an exoplanet taken in wavelengths beyond 5 microns.
The hunt for the source of a gravitational wave signal came up short, but it revealed a supernova with a curious double-peaked light curve.
Astrobites reports on the origins of a purported interstellar meteorite that has made a big splash in the news (and the Pacific Ocean).
How do radio jets end up in X, S, or Z shapes? Simulations explore how precession might play a role.
Learn about engineer-turned-astronomer Katie Merrell’s journey to becoming a data editor for the AAS journals, and read up on how the data editors help our authors organize and present their data.
Researchers have analyzed images and spectra of hundreds of galaxies to determine if star formation proceeds smoothly or in fits and starts.
Astrobites reports on a potential new formation channel for intermediate-mass black holes, which are an important stepping stone on the way to creating supermassive black holes.
New research dives into tiny gaps and dips on the H–R diagram to study the connection between stellar interiors and stellar activity.
“Ice, Ice, Maybe?” Probably not in the case of comet 46P/Wirtanen.
We’ve measured more elements in HD 222925’s spectrum than we have for any other star except for the Sun. Could this star provide a new benchmark for our understanding of how heavy metals are created?
Astrobites reports on how challenging ground-based observations can bring the aurorae of Jupiter’s moon Io into view.
An extremely flat galaxy, seen edge on, has a wealth of subtle imperfections that hold the clues to the galaxy’s history.
