What Is a Nebula? | Facts, Definition, What Are They?, Types This nebula has many colors Astronomers know that the orange color is hydrogen, the red color in the nebula is sulfur, and the green color is oxygen When you think about a nebula, you can think of it it two ways: a nebula is a giant cloud of dust and gas in space, and a nebula is the place where stars are formed and born
Types of Nebulae | Galaxies, Globular Open Clusters - The Nine Planets A typical diffuse nebula is a few hundred light-years across (NGC 2264 shown; see also the Horsehead Nebula) Planetary Nebulae Planetary nebulae are shells of gas thrown out by some stars near the end of their lives Our Sun will probably produce a planetary nebula in about 5 billion years
Nebulae Facts For Kids | What?, Formation, Importance, Size, Comparison The biggest Nebula ever discovered is the Tarantula Nebula At first, it was thought to be a star, but later on, in 1751, it got its proper recognition The Tarantula Nebula has an apparent magnitude of +8, and it is 160,000 light-years away
Monoceros Constellation | Facts, Information, Mythology, History . . . The Red Rectangle Nebula The Red Rectangle Nebula, also known as HD 44179, is a protoplanetary nebula located at around 2 3-kilo light-years away from us It has an apparent magnitude of 9 02 The star situated in the center of the nebula is a binary system NGC 2232 NGC 2232 is a bright open cluster centered on the star 10 Monocerotis

Corona Australis Constellation - The Nine Planets Corona Australis Nebula The Corona Australis Nebula is a bright reflection nebula, located at around 420 light-years away from us This nebula is formed by several bright stars that are caught up in a dark cloud of dust, and this cloud is also a star-forming region, with clusters of young stars embedded within it
Orion Constellation | Facts, Information, History Definition This nebula can be found a third of a degree from the Horsehead Nebula NGC 2023 is around 1,467 light-years away from Earth Monkey Head Nebula The Monkey Head Nebula, designated as NGC 2174, is an emission nebula classified as an H II region It is associated with the open cluster NGC 2175, also located in Orion
The Origin of the Solar System l The Big Bang - The Nine Planets At about this time, about 1 million years after the nebula cooled, the star would generate a very strong solar wind, which would sweep away all of the gas left in the protoplanetary nebula If a protoplanet was large enough, soon enough, its gravity would pull in the nebular gas, and it would become a gas giant
Eta Carinae (η Carinae) | Facts, Information, History Definition Eta Carinae is located in the constellation of Carina Eta Carinae is engulfed by the Homunculus Nebula This nebula is embedded within the much larger Carina Nebula, a large star-forming H II region Carina was part of a larger constellation called the Argo Navis – this constellation represented the ship of Jason and the Argonauts
Sadr (γ Cygni) Star | Facts, Information, History Definition However, the nebula isn’t physically related to the star Sadr, it is merely in the same line of sight The nebula itself is located far away from the star, at a distance of around 4,900 light-years There is a blue O9-class star that illuminates the nebula, however, it is obscured by interstellar dust and much about the star remains unknown
