NGC 7027, also known as the Jewel Bug Nebula or the Magic Carpet Nebula, [6] is a very young and dense planetary nebula [7] located around 3,000 light-years ...
NGC 2440 is a planetary nebula, one of many in our galaxy. Its central star, HD 62166, [1] is possibly the hottest known white dwarf, about 400,000°F(200,000°C). The nebula is situated in the constellation Puppis. It was discovered by William Herschel on March 4, 1790. He described it as "a beautiful planetary nebula of a considerable degree ...
NGC 1491, also known as LBN 704, SH2-206 or the Fossil Footprint Nebula, is an emission type bright nebula located about 9,800 light years away from Earth in the constellation of Perseus. [1] The nebula gets its deep red coloration due to many massive stars (such as BD+50 866 ) embedded within NGC 1491 producing large amounts of ultraviolet ...
The Cat's Eye Nebula (also known as NGC 6543 and Caldwell 6) is a planetary nebula in the northern constellation of Draco, discovered by William Herschel on February 15, 1786. It was the first planetary nebula whose spectrum was investigated by the English amateur astronomer William Huggins , demonstrating that planetary nebulae were gaseous ...
Shapley 1 (Sp 1 or PLN 329+2.1) [3] is an annular planetary nebula in the constellation of Norma with a magnitude of +12.6. [4] As viewed from Earth, it is peculiar in that it seems to be a non-bipolar, torus-shaped planetary nebula. However, it is thought that this is due to the viewpoint of looking directly down on a binary system whose orbit ...
The Frosty Leo Nebula is a protoplanetary nebula (PPN) located roughly at 3000 light-years away from Earth in the direction of the constellation Leo. It is a spectral [ 3 ] bipolar nebula . Its central star is of optical spectral type K7II, [ 4 ] by itself called Frosty Leo . [ 5 ]
The Cotton Candy Nebula, also known as IRAS 17150-3224, is a bipolar nebula in the constellation of Scorpius. It is considered to fall into an unusual category of nebulae known as protoplanetary nebulae or post-AGB stars. [1] Protoplanetary nebulae are created by stars transitioning from the asymptotic giant branch to the planetary nebula phase.
The nebula is arranged in three concentric shells, with the outermost shell being about 20–30% larger than the inner shell. [7] The owl-like appearance of the nebula is the result of an inner shell that is not circularly symmetric, but instead forms a barrel-like structure aligned at an angle of 45° to the line of sight.
