This spectacular image of the Orion Nebula, complete with its incredibly rich star-formation region, ... More was obtained from multiple exposures using the HAWK-I infrared camera on ESO’s Very Large ...

One of the largest emission nebulae in the far northern sky can be found in IC 1396, a bright glow in Cepheus that contains several complex objects. Among them are the red supergiant star Mu Cephei; ...

This image taken with the NASA/ESA Hubble Space Telescope showcases the emission nebula NGC 2313. Emission nebulae are bright, diffuse clouds of ionized gas that emit their own light. ESA/Hubble, R.

ABSTRACT Recent analyses of nebular spectra have resulted in discrepant abundances from CNO forbidden and recombination lines. We consider independent methods of determining ion abundances for ...
