What happens to Mars when it’s struck by a coronal mass ejection? Two spacecraft on opposite sides of the planet gave us a unique perspective on the event.
The non-detection of six supernovae allowed researchers to place limits on the properties of the exploded stars’ mass-donating companions.
Astrobites reports on the modeling of small bodies in the outer solar system and how this finicky, incremental process can have far-ranging impacts.
By modeling the motions of the Milky Way and our galactic neighbor, researchers have placed a constraint on the cosmological constant, and by extension, dark energy.
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.
