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.

An accreting stellar-mass black hole embedded in a supernova remnant is potentially a powerful cosmic particle accelerator.

Epoch of Reionization

A Seriously Dusty Supernova

A supernova discovered in 2010 appears to have created tens of thousands of Earth masses of dust.

NGC 1068

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.
