Faraway Fossils: Clues from a High-Redshift Galaxy
Shining bright from billions of light-years away, the universe’s first galaxies provide a wealth of information regarding galaxy formation and evolution across cosmic time. What have new observations of one such galaxy contributed to our understanding?
Seeing an Active Galactic Nucleus with 20/20 X-Ray Vision with XRISM
Astrobites reports on the first observations of an active galactic nucleus by the X-ray Imaging and Spectroscopy Mission.
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.
