JWST Field - 20,000+ galaxies

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?

NGC 4151

Astrobites reports on the first observations of an active galactic nucleus by the X-ray Imaging and Spectroscopy Mission.

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.

The star SOS1 is not like its neighbors — what do high-precision chemical abundances tell us about where this star might have come from?

36 images of supernova host galaxies

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.
