The nebula was imaged by the Hubble Space Telescope in the 1990s. The primary component of the central binary is the hot core of a star that reached the end of its main-sequence life cycle, ejected most of its outer layers and became a red giant , and is now contracting into a white dwarf .
The widely accepted modern variant of the nebular theory is the solar nebular disk model (SNDM) or solar nebular model. [1] It offered explanations for a variety of properties of the Solar System, including the nearly circular and coplanar orbits of the planets, and their motion in the same direction as the Sun's rotation.
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 image of the Horsehead Nebula captures the iconic nebula in a whole new light. NASA releases 'unprecedented' Horsehead Nebula image captured by James Webb Space Telescope. What to know about ...
NASA’s Webb Space Telescope has revealed the sharpest images yet of a portion of a horse-shaped nebula, showing the “mane” in finer detail. The Horsehead Nebula, in the constellation Orion ...
DALLAS (AP) — NASA’s Webb Space Telescope has revealed the sharpest images yet of a portion of a horse-shaped nebula, showing the “mane” in finer detail. The Horsehead Nebula, in the constellation Orion, is 1,300 light-years away. A light-year is nearly 6 trillion miles (9.7 trillion kilometers).
Has been named the “Heart nebula” because of its resemblance to a human heart. Henize 70 (N70 or DEM L301) [47] 300 ly (92 pc) [48] H II region: The N 70 Nebula, in the Large Magellanic Cloud has a shell structure and is really a bubble in space. It is a "Super Bubble". Barnard's Loop: 300 ly (92 pc) [49] [50] H II region
NASA's Fermi Gamma-ray Space Telescope spots 'superflares' in the Crab Nebula. At the center of the Crab Nebula are two faint stars, one of which is the star responsible for the existence of the nebula. It was identified as such in 1942, when Rudolf Minkowski found that its optical spectrum was extremely unusual. [51]
