The nebula is located in the Carina–Sagittarius Arm of the Milky Way, [6] at a distance of approximately 5.5 kilolight-years from the Sun. [7] The nebula is a high mass filamentary cloud structure spanning ~320 ly. In the visible part of the spectrum, it emits mainly in red (from hydrogen atoms) and blue (from oxygen atoms). [8]
NGC 6357 is a diffuse nebula near NGC 6334 in the constellation Scorpius. The nebula contains many proto-stars shielded by dark discs of gas, and young stars wrapped in expanding "cocoons" or expanding gases surrounding these small stars. It is also known as the Lobster Nebula.
A nebula that is visible to the human eye from Earth would appear larger, but no brighter, from close by. [6] The Orion Nebula, the brightest nebula in the sky and occupying an area twice the angular diameter of the full Moon, can be viewed with the naked eye but was missed by early astronomers. [7]
The Cone Nebula is an H II region in the constellation of Monoceros. It was discovered by William Herschel on December 26, 1785, at which time he designated it H V.27. The nebula is located about 830 parsecs or 2,700 light-years from Earth. The Cone Nebula forms part of the nebulosity surrounding the Christmas Tree Cluster.
The Horsehead Nebula is famously known for…looking like a horse’s head. Webb captured the top of the "horse's mane," giving us the sharpest infrared images of the region to date: https://t.co ...
The star R Monocerotis has lit up a nearby cloud of gas and dust, but the shape and brightness slowly changes visibly even in small telescopes over weeks and months, and the nebula looks like a small comet. [8] One explanation proposed for the variability is that dense clouds of dust near R Mon periodically block the illumination from the star. [9]
English: What looks much like craggy mountains on a moonlit evening is actually the edge of a nearby, young, star-forming region NGC 3324 in the Carina Nebula. Captured in infrared light by the Near-Infrared Camera (NIRCam) on NASA’s James Webb Space Telescope, this image reveals previously obscured areas of star birth.
The nebula is known as S 142 in the 1959 Sharpless catalog (Sh2-142). [2] It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. The NGC 7380 complex is located at a distance of approximately 8.5 kilolight-years from the Sun , in the Perseus Arm of the Milky Way .
