Selections from 2024: Weighing the North Star
Though the North Star appears to be an unwavering single star, it’s actually a variable star belonging to a triple star system. This year, researchers reported a new mass estimate for the North Star and discovered spots on its surface.
A chance alignment between galaxies allows astronomers to study a single star system as it was when the universe was just 6 billion years old.
Astrobites reports on the potential habitability of Teegarden’s Star b, a promising Earth-like planet.
How has the Crab Nebula supernova remnant changed since the Hubble Space Telescope observed it in 1999–2000?
A recent study looks to the nearest rubble-ridden systems for the potential origins of interstellar objects that have visited our solar system.
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.
Astrobites reports on RACS J0320−35, a quasar that appears to be breaking a cosmic limit by consuming matter faster than theory should allow.
Researchers examine whether the black holes at the centers of little red dots could have been born in the collapse of dark matter halos.
Researchers use an unlikely tool — distant beacons called quasars — to study the constant inflow and outflow of gas to and from our galaxy.
