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.

The detection of highly ionized neon gas near M83’s galactic nucleus reveals an energetic signature that is commonly linked to the presence of an active galactic nucleus (AGN), which is the calling ...

The universe's missing matter may have finally been found. Astronomers think regular matter — that is, the stuff that isn't dark matter — makes up about 15% of the universe's total mass.

Her work, alongside collaborator Simone Ferraro of Lawrence Berkeley National Laboratory, suggests that the hidden matter is in the form of ionized hydrogen gas that is much more spread out around ...

The missing matter has been hiding out as invisible ionized hydrogen gas, which forms halos around galaxies far larger and more frequently than earlier estimations, according to a report in a physics ...
