DESI Legacy Imaging Surveys
The Dark Energy Spectroscopic Instrument (DESI) is a brand-new instrument installed at the Kitt Peak National Observatory (KPNO). It’s ready to come online, and it follows on the heels of the DESI Legacy Imaging Surveys.
Powerful Gamma-Ray Burst Turns Out to be Magnetar Flare
Powerful burst of X-rays and gamma rays in April 2020 turned out to be from a magnetar in a galaxy 11.4 million light-years away.

NANOGrav Project Uses Pulsars to Potentially Detect Gravitational Waves
Members of the NANO Grav collaboration are looking for the ripples that pass through space-time when gravitational waves run through the universe.
ALMA Captures Distant Colliding Galaxy on Verge of ‘Dying’
In new work, researchers used ALMA to watch a galaxy ID2299 eject a massive amount of its cold gas content. Combined with rapid star formation, ID2299 will run out of gas in a few tens of million years.
Pulsar Acceleration Used to Calculate Milky Way’s Dark Matter Density
By looking carefully at the timing of pulsars around the Milky Way, researchers can tease out the tiny motions due to the tiny weird acceleration associated with the expansion of our universe and determine the dark matter density.
Youngest, Fastest Magnetar Studied by Chandra
New research done using the Chandra X-ray telescope examines the youngest magnetar, which was observed last year using the Swift Observatory during a bright flash of gamma rays.
Forgotten Kepler Planet Candidate Orbits Triple-Star System
In new research presented at the AAS meeting, researchers present a follow-up on KOI-5Ab, the second potential planet discovered by Kepler, which orbits in a triple-star system
