Gaseous nebulae as a research area encompasses the observational, theoretical, and numerical study of ionized, atomic, and molecular gas clouds in interstellar and circumstellar environments, focusing on their physical conditions, chemical composition, and dynamical evolution. Research addresses radiative transfer, emission-line diagnostics, photoionization and shock-excitation mechanisms, and the impact of stellar feedback from massive stars and supernovae on nebular structure. It also investigates nebulae as laboratories for plasma physics, dust–gas interactions, and nucleosynthesis yields, and as probes of galactic structure, star-formation processes, and the interstellar medium across different metallicities and cosmic epochs.
The NASA/ESA/CSA James Webb Space Telescope recently imaged NGC 2392 (also known as the Lion Nebula), named for its distinctive appearance, which resembles a lion's face seen head-on.

Using the Multi Unit Spectroscopic Explorer (MUSE) and the Manchester Echelle Spectrograph (MES), astronomers from Turkey and Mexico have investigated a planetary nebula discovered two centuries ago, known as NGC 6563. Results ...
A new study of two supernova remnants, the debris left behind after stars explode, suggests the explosions came from stellar siblings that once orbited each other. The first star's detonation sent its binary companion hurtling ...
