What if the earliest galaxies weren’t unusual at all? Maybe the answer lies in relics left over from the universe’s first moments.

Meet Dr. Carolyn Kierans: 2025 HEAD Early Career Prize winner and the astrophysicist chasing the antimatter at the center of our galaxy.

Today we interview solar physicist and 2026 Hale Prize recipient Dr. Yi-Ming Wang about the discoveries that shaped our understanding of the solar wind, the Sun’s magnetic field, and a career built on...

Today we interview UCLA planetary scientist David Jewitt, who helped discover the Kuiper Belt and is now studying some of the Solar System’s strangest visitors!

The email asking you to referee your first paper is coming. Here's a practical, step-by-step guide for that exact moment, built from the AAS peer review workshop.

What if JWST’s early massive galaxies are not overestimated, but underestimated? A bottom-heavy IMF could hide tons of mass in faint stars.

Something is missing in the middle. In JWST JADES galaxies, young clumps drop out in the inner regions, while clump structure shifts from the outskirts to the center.

Are cosmic clumps “homegrown”, or fueled by fresh inflow? Today’s authors find that star-forming clumps are usually more metal-poor than the disks around them.

Astrobites coverage of Day 1 of AAS 247!

JWST reveals galaxies that built up heavy elements at record speed, reaching near-modern metallicities only a billion years after the Big Bang.

You think stars form quietly? Think again. In the early universe, galaxies were packed with star-forming clumps. Some disrupted quickly, while others survived. Today’s paper reveals which lived and wh...

What do you get when baby galaxies crash and light up in UV? A surprising early signature of cosmic dust.

A tiny galaxy, barely metal-enriched, is packed with massive stars. Could it hold clues to the universe’s first stars?

Today's bite explores how JWST reveals a surprising dust curve in a distant galaxy, challenging what we know about cosmic dust!
