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.
Hace 1 día · The Southern Ring Nebula was imaged in December 2022 by the James Webb Space Telescope (JWST), which revealed molecular hydrogen gas forming the nebula's "exoskeleton." This refers to warm gas ...
Hace 1 día · The images captured by the James Webb Space Telescope show the "mane" of the Horsehead Nebula in "unprecedented" detail, NASA said. One image processed by NASA shows a delicate blue structure ...
Hace 2 días · 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 with […]
7 de feb. de 2024 · Today, Hubble has observed many of these nebulas and found a wide range of complicated and extraordinary shapes, from tunnels to interlocking rings. The Cat's Eye Nebula, for example, consists of 11 bubbles of gas. The Helix Nebula looks like a giant eye staring at us through space.
3 de may. de 2023 · There are different types of nebulae, ranging from sites where stars are being born under gravitational pressures to expanding gaseous remnants thrown off by dying stars. Hubble Senior Project Scientist, Dr. Jennifer Wiseman, takes us on a tour of some of our universe’s most incredible Nebulae.
