True color image of the Trifid Nebula, showing complex gas and plasma structure. A nebula (Latin for 'cloud, fog'; pl.: nebulae, nebulæ, or nebulas) is a distinct luminescent part of interstellar medium, which can consist of ionized, neutral, or molecular hydrogen and also cosmic dust.
Several types of nebulae exist, and each individual nebula is a unique showcase of the phenomena and processes happening within. They often live side by side, with smaller nebulae populating larger clouds of gas and dust to form giant complexes of star birth and death.

Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries."

29. Apr. 2024 · NASA’s James Webb Space Telescope has captured the sharpest infrared images to date of a zoomed-in portion of one of the most distinctive objects in our skies, the Horsehead Nebula. These observations show the top of the “horse’s mane” or edge of this iconic nebula in a whole new light, capturing the region’s complexity ...
Nebula, any of the various tenuous clouds of gas and dust that occur in interstellar space. The term was formerly applied to any object outside the solar system that had a diffuse appearance rather than a pointlike image, as in the case of a star. This definition, adopted at a time when very.
