The Eskimo Nebula (NGC 2392), also known as the Clown Face Nebula, Lion Nebula, [4] or Caldwell 39, is a bipolar [5] double-shell [6] planetary nebula (PN). It was discovered by astronomer William Herschel in 1787.

2008年3月23日 · The Eskimo Nebula is clearly a planetary nebula, and the gas seen above composed the outer layers of a sun-like star only 10,000 years ago. The inner filaments visible above are being ejected by strong wind of particles from the central star.

2014年7月14日 · The Eskimo Nebula is a bipolar planetary nebula located in Gemini constellation. It is sometimes also known as the Clown Face Nebula. The nebula has the designation NGC 2392 in the New General Catalogue. It got the nickname Eskimo because its shape resembles a head wearing a fur-lined parka hood.

2023年2月20日 · The Eskimo or Clown Face Nebula (NGC 2392 and Caldwell 39) in Gemini is arguably the finest planetary nebula in the winter sky. The Hubble Space Telescope’s iconic image from 2000 has featured heavily in astronomy publications and on the Internet, making the nebula one of the most famous and recognisable objects in the night sky.

The Eskimo Nebula is also called Caldwell 39 or the Clown face nebula. The nebula is more than 2,870 light-years from earth. William Herschel discovered the nebula in Slough England on January seventeenth of 1786.

2000年1月24日 · In its first glimpse of the heavens following the successful December 1999 servicing mission, NASA's Hubble Space Telescope has captured a majestic view of a planetary nebula, the glowing remains of a dying, Sun-like star. This stellar relic, NGC 2392, was first spied by William Herschel in 1787.

2023年4月27日 · Eskimo Nebula (NGC 2392) The Eskimo Nebula, also known as NGC 2392, is a beautiful and fascinating astronomical object located in the constellation Gemini. It is one of the most well-known and studied planetary nebulae, and it has captured the imaginations of astronomers and stargazers alike.

How to find the Eskimo Nebula? The Eskimo Nebula in the constellation of Gemini is relatively easy to find: You start with the 3.5m star Wasat (Delta Gem), which forms an almost equilateral triangle with the two 5mag stars 63 and 58 Gem.

Most of the clusters, nebulae and galaxies that are grouped together under the collective term “deep sky objects” are most visible from a dark countryside location. One of the exceptions is the planetary nebula NGC 2392, which bears the promising nickname the Eskimo Nebula.

The Eskimo is a classic planetary nebula, particularly for larger scopes. Discovered by William Herschel in 1787, the Eskimo is 10th magnitude, with a 10.5 magnitude central star. Relatively small, the nebula subtends a mere 20". It lies some 3700 light years distant.
