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.
Probing Dust in the Disk of a Growing Giant Planet
PDS 70c is the first exoplanet known to host a circumplanetary disk, where moons are potentially forming.
A Lyman-Leaking Galaxy Merger Confirmed with JWST
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.
