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

Cats Eye Nebula - The Nine Planets Type: planetary nebula; This is one of the most complex of the planetary nebulae The HST images seem to indicate that the central star is actually a binary system and that the nebula we see today is actually the result of at least two separate events See the NASA press release for more info
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
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
Trifid Nebula - The Nine Planets Trifid Nebula M 20 RA 18:02, Dec -23:02 (Sagittarius) Distance: 2000 ly; Type: emission reflection nebulae; The Trifid Nebula gets its name from the three dark lanes the divide it The red part is an emission nebula powered by a bright triple star CC 24537; the fainter blue part is a reflection nebula surrounding a hot O-type star
