Featured Image: Jets and Outflows from Protostars
Wide-angle outflows and narrow, structured jets dominate this view of two protostars and give a glimpse into the process of star and planet formation.
Reading a Chapter of Galactic History from a Single Star
The star SOS1 is not like its neighbors — what do high-precision chemical abundances tell us about where this star might have come from?
Looking Back on Astronomy in 2024 with AAS Nova
2024 has been another wonderful year for astronomy! Check out our year-end top 10 post to see what readers were most fascinated by this year.
Selections from 2024: First Images of Turbulent Eddies in the Outer Corona
Using the Parker Solar Probe, researchers have collected images of turbulent eddies in the Sun’s outer corona. This likely marks the first time this instability has been directly imaged so far out in the Sun’s atmosphere.
Selections from 2024: Sampling Shredded Stars in the Infrared
Dust might be responsible for hiding many tidally disrupted stars from view — but a new search at infrared wavelengths has revealed them at last.
Selections from 2024: Which Came First, Supermassive Black Holes or Galaxies?
Researchers have proposed a new solution to a cosmic chicken-and-egg problem, suggesting a new role for supermassive black holes in the formation of stars in young galaxies.
Selections from 2024: Possible Proto-Galactic Fragments in the Milky Way
Two stellar structures discovered in the Milky Way this year may be fragments of proto-galaxies that formed before our galaxy was assembled.
Selections from 2024: First Unambiguous Detection of Water on an Asteroid
Researchers have spotted what might be water on asteroids before, but 2024 brought the first definitive detection.
Selections from 2024: Faintest Known Milky Way Satellite Discovered
The Milky Way’s faintest known satellite contains just 57 stars and has a total mass of 16 solar masses: meet Ursa Major III/UNIONS 1.
Selections from 2024: Mapping Quasars Across the Universe
Need more than a million quasars for your study of large-scale structure, accretion, or black hole growth? The Quaia catalog has you covered.
Selections from 2024: Earth Predicted to Gain (and Lose) a Mini-Moon
In September 2024, researchers predicted that the asteroid 2024 PT5 would soon join Earth as a short-lived “mini-moon.” Today, we’re giving a brief recap of how the prediction played out.
