Primordial Planetesimals from the Guts of Population III Stars
How early did planets form in the universe? A recent study used simulations to find that planetesimals could have formed significantly earlier than previously thought.
Astrobites reports on JWST observations of dust that has survived being expelled from a galaxy into the circumgalactic medium.
Researchers have discovered a comet-shaped nebula surrounding a pulsar speeding through the remains of its progenitor star.
JWST observations of the most recent interstellar visitor reveal a coma dominated not by water, as expected for solar system comets, but instead carbon monoxide.
PDS 70c is the first exoplanet known to host a circumplanetary disk, where moons are potentially forming.
Galaxies of Many Colors
Astrobites reports on whether our methods for weighing galaxies can help save cosmology from JWST’s universe-breaking galaxies.
An accreting stellar-mass black hole embedded in a supernova remnant is potentially a powerful cosmic particle accelerator.
When two galaxies collide, they spark new star formation that can emit tons of powerful radiation. A recent study observes such a system and connects this process to the reionization of the universe.
