The Orion nebula is the nearest nebula to the Earth. Planetary Nebula, MyCn18.

The Crab Nebula is the leftover, or remnant, of a massive star in our Milky Way that died 6,500 light-years away. In a stellar nursery called the Serpens Nebula, nearly 1,300 light-years away, a young star’s game of shadow play is revealing secrets of its unseen planet-forming disk. These nebulae seen by NASA's Spitzer Space Telescope, display two regions of star formation that are hidden behind a haze of dust when viewed in visible light, known officially y their catalog numbers, IRAS 19340+2016 and IRAS19343+2026. MyCn18, a young planetary nebula located about 8,000 light-years away. Like its mythological namesake, the nebula is # 2. Like other stars its size, the Sun has an outer atmosphere that is slowly but steadily flowing off into space. Up until the 1920's distant galaxies were classified as nebulae. Explanation: Braided, serpentine filaments of glowing gas suggest this nebula's popular name, The Medusa Nebula. Nebulae which exist outside the Milky Way are known as extra-galactic nebulae. The Orion Nebula is the closest star forming region to Earth, it lies 1,300 light years away and is thought to be around 25 light years across.

Below Orion's belt is a fuzzy area known as the Great Nebula of Orion. In this nebula is a bright star cluster known as the Trapezium, marked by four bright stars near the image center. The featured image is a composite of three exposures in different colors: red as emitted by hydrogen gas, yellow as emitted by sulfur , and blue as emitted by oxygen . Also known as Barnard 33, the unusual shape was first discovered on a photographic plate in the late 1800s.

A supernova of a star more than about 10 times the size of our sun may leave behind the densest objects in the universe—black holes. One of the most identifiable nebulae in the sky, the Horsehead Nebula in Orion, is part of a large, dark, molecular cloud. Located about 6,500 light years away, the Soul Nebula spans about 100 light years and is usually imaged next to its celestial neighbor the Heart Nebula (IC 1805). The sun formed in a nebula. The near-infrared vision of NASA’s Hubble Space Telescope captured the shadow cast by the … Also known as Abell 21, this Medusa is an old planetary nebula some 1,500 light-years away in the constellation Gemini.
