This surprising finding, made possible by Webb's Mid-Infrared Instrument (MIRI), reveals highly ionized neon gas that could be a telltale signature of an active galactic nucleus (AGN), a growing ...

Highly ionized neon gas detected at the center of the spiral galaxy Messier 83 by the Mid-Infrared Instrument (MIRI) aboard the NASA/ESA/CSA James Webb Space Telescope could be a telltale signature of ...

A new study by 75 scientists across institutions around the world suggests that this missing matter is actually ionized hydrogen gas surrounding galaxies, which stretches much further than we thought.
