First Detection of a Glycine Isomer in the Interstellar Medium
Researchers have detected glycolamide, a chemical cousin to the simplest amino acid necessary for life on Earth, in the interstellar medium for the first time.

Lonely Neutrinos: IceCube’s First Population Limits
By the time you finish this sentence, trillions of neutrinos will have passed harmlessly through your body. But, where are all of them coming from? Astronomers still aren’t sure, but they’re starting to put limits on the answer.
Sandy, Briny Water on Mars Has a Better Chance of Remaining Liquid
Lab experiments show that mixing Martian surface material into briny liquid helps water remain a liquid under colder, drier conditions.
Fast Radio Burst Roundup
Fast radio bursts have puzzled astronomers for more than 15 years now, but they may be getting close to an explanation for these powerful flashes.
JWST Validates a New Tool for Studying Quasars
Comparing quasar observations made at key optical and infrared wavelengths shines a light on the best way to study quasar outflows with JWST.
Solar Storm Versus Mars
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.
What We Learn by Not Detecting Supernovae
The non-detection of six supernovae allowed researchers to place limits on the properties of the exploded stars’ mass-donating companions.
A New Way to Constrain Dark Energy
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.
Spotting an Exoplanet in the Mid-Infrared
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.
How We Lost a Gravitational Wave Source and Gained a Supernova
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.
