The nebula lies at an approximate distance of 4,200 light years from Earth. This page was last modified on 28 March 2019, at 01:22. The color of the gas in the nebula depends on its composition. - Ms. Sign (100%). The term planetary nebula was originally used by William Herschel in the 1780s, who thought the objects looked like the planets Uranus and Neptune when observed in telescopes, and the term has stayed in use. - Shibalien Elite (Alien) (200%) The nebula, featured here, is about 1.4 light-years in extent and located about 5000 light-years away toward the constellation of Puppis. The fast-moving gas clouds are collimated into streamers on one side and a jet on the other. The nebula’s peculiar shape earned it the name Calabash, and it was nicknamed the Rotten Egg Nebula because it has a large amount of sulphur, which can smell like a rotten egg when combined with other elements. The gas flow we see now is believed to have resulted from a sudden acceleration some 800 years ago. - General GreGory (Alien) (100%) The gas cloud has been dubbed the Rotten Egg Planetary Nebula because it contains unusually high amounts of sulfur, an element that, when combined with other elements, can smell like a rotten egg. The nebula lies at an approximate distance of 4,200 light years from Earth. Blue corresponds to ionized nitrogen and hydrogen.[6]. The nebula's unusual shape came to light as astronomers identified the hottest areas, which reach scorching temperatures as expanding gases zoom at warp speed and collide with other objects in the star cluster. It is mandatory to procure user consent prior to running these cookies on your website. The Calabash Nebula is about 1.4 light years long and has a radius of 0.7 light years. Instagram-worthy photo ops of a star's last breaths are actually a rare opportunity for astronomers. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days). Incandescent blues, yellows and oranges visible to the human eye in this image are the result of Hubble filtering out everything except those elements. Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between below 3,500K based on the notes from Harvard University. An Astronomical Unit is the distance between Earth and the Sun. Radius: 0.7 light years By direct calculation using distances of 4,200 and 5,000 ly. [3] However some sources put it lower at only 4,200 light years. Icke, V. and Preston, H. (1989). (2001). [1] The name Calabash was proposed due to its unusual shape. Astronomers have so far proposed theories involving a binary companion or a massive planet and an accretion disk. This has created the bipolar (two lobed) structure that is apparent in images of the nebula. The compounds are likely produced as a result of shock waves passing through the clouds of gas. The next stage is Altair. … The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. The fastest gas is shown in yellow and is moving at over one million kilometers per hour (621,371 miles per hour).

Spectacular jets of streaming gas can be seen in this recently released photograph by the Hubble Space Telescope. You also have the option to opt-out of these cookies. Detection of an inner torus in the protoplanetary nebulae OH231.8+4.2. is the number of times that the star is from the Earth compared to the Sun. It is believed to be located in the open cluster Messier 46 since it lies at the same distance of 5,000 light years and also has the same radial velocity and proper motion. 2.1 Celadon Mykoserocin; 3 Location; Defenders. This image taken by the NASA/ESA Hubble Space Telescope shows the star going through a rapid transformation from a red giant to a planetary nebula, during which it blows its outer layers of gas and dust out into the surrounding space. The nebula lies in the bright, large open star cluster Messier 46. Update your browser for more security and the best experience on this site. - Ms. Sign (100%). Based on the spectral type (M10III+A C) of the star, the star's colour is red . By continuing to use the site, you agree to the use of cookies. The Calabash Nebula, also known as the Rotten Egg Nebula and OH231.8+4.2, will likely develop into a full bipolar planetary nebula over the next 1000 years.
