It is also known as the Lobster Nebula. [ 4 ] [ 5 ] This nebula was given the name War and Peace Nebula by the Midcourse Space Experiment scientists because of its appearance, which, in infrared images the bright, western part resembles a dove, while the eastern part looks like a skull. [ 6 ]
Over the course of around 10,000 years the white dwarf will cool down dramatically, diminishing the light of the nebula and making it only visible in a long-exposure photograph. [2] The nebula of NGC 6565 is thought to be composed of three different zones. The inner zone, which is the bright circle seen in the featured image, is heavily ionized ...
IC 289 is a planetary nebula in the constellation Cassiopeia. [3] It was discovered by Lewis Swift in early September 1888. It lies close to the 10th magnitude star BD +60° 0631. N.J. Martin described IC 289 as "A nice, faint round planet like planetary nebula. The uniform oval disc shows some irregularity in brightness but is not obviously ...
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.
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
The nebula is rich in carbon, and is a very interesting object for the study of carbon chemistry in dense molecular material exposed to strong ultraviolet radiation. [18] The spectrum of NGC 7027 contains fewer spectral lines from neutral molecules than is usual for planetary nebulae.
NGC 3132 (also known as the Eight-Burst Nebula, [2] the Southern Ring Nebula, [2] or Caldwell 74) is a bright and extensively studied planetary nebula in the constellation Vela. Its distance from Earth is estimated at 613 pc or 2,000 light-years .
NGC 5189 (Gum 47, IC 4274, nicknamed Spiral Planetary Nebula) is a planetary nebula in the constellation Musca. It was discovered by James Dunlop on 1 July 1826, who catalogued it as Δ252. [ 1 ] For many years, well into the 1960s, it was thought to be a bright emission nebula.
