An Interstellar Comet’s Coma Composition
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.
What do the latest JWST data say about the notable ultra-hot Jupiter WASP-121b?
A Seriously Dusty Supernova
A supernova discovered in 2010 appears to have created tens of thousands of Earth masses of dust.
Astrobites reports on whether the correlation between galactic radio, infrared, and gamma-ray emission is truly a sign that cosmic-ray electrons deposit all their energy before they can escape to intergalactic space.
Finishing Off an Asteroid
Astronomers may have spotted the crumbs of a recently eaten asteroid around a white dwarf star.
