How Many Kilonovae Will Rubin Observatory Help Us Spot?
The upcoming Vera C. Rubin Observatory Legacy Survey of Space and Time will detect an astonishing number of transients — including kilonovae from colliding neutron stars.
A Dark Matter Origin for Little Red Dots
Researchers examine whether the black holes at the centers of little red dots could have been born in the collapse of dark matter halos.
Fueling Up: How Does the Milky Way Get Its Star-Forming Gas?
Researchers use an unlikely tool — distant beacons called quasars — to study the constant inflow and outflow of gas to and from our galaxy.
Monthly Roundup: Interstellar Visitor 3I/ATLAS
The discovery of interstellar comet 3I/ATLAS was one of the top astronomy stories of 2025. Though the comet is now heading back to interstellar space, research into its properties and origins continues.
Getting a Peek of Kitt Peak National Observatory
A mountain top in the Arizona desert scattered with telescopes, the Kitt Peak National Observatory is home to cutting-edge research and cultural connections.
JWST Follows Up on a Rare Gamma-Ray Burst
Lasting multiple hours and featuring several bursts, GRB 250702B is a rare, powerful, and unusual gamma-ray burst. What do JWST observations tell us about the host galaxy and origins of this event?
Supernovae, Shocks, and Spindown: A Possible Origin Story for Ultra-Long-Period Pulsars
New research suggests that ultra-long-period pulsars might begin their lives as massive stars in close binary systems.
When Winds Collide: Predicting the Effects of Stream Interaction Regions
Though less destructive than coronal mass ejections, moderate space weather events like stream interaction regions can still cause geomagnetic storms. Researchers have used machine learning to investigate the drivers behind these events.
