M42, the great Orion Nebula, is a region of very young stars within a giant molecular cloud whose total mass is estimated to be approximately 500,000 times that of the Sun About 1600 light-years from Earth, M42 lies on the edge of its parent giant molecular cloud, which in turn is but one of a vast systems of such clouds found in this part of the Galaxy.
What else can I help you with?
Emission nebulae like M42 occur only near stars that emit large amounts of?
Emission nebulae like M42 occur near stars that emit large amounts of ultraviolet radiation. This intense radiation ionizes the surrounding gas, causing it to emit light in various colors, giving rise to the beautiful glowing clouds we observe in such nebulae.
What is the most famous nebula?
The Orion Nebula (M42) is one of the most famous and brightest nebulas in the night sky. It is a stellar nursery where new stars are forming and is visible to the naked eye in the constellation of Orion.
What nebulae can you see with the naked eye?
Several nebulae are visible to the naked eye, with the Orion Nebula (M42) being the most prominent, located in the Orion constellation. The Lagoon Nebula (M8) and the Trifid Nebula (M20) in the Sagittarius constellation are also observable under dark skies. Additionally, the Dumbbell Nebula (M27) in Vulpecula can be seen with good visibility conditions, although it may appear faint. Visibility depends on light pollution and atmospheric conditions.
Why doesn't the Horsehead Nebula glow like other nebulae?
Horsehead Nebula doesn't glow like other nebulae because it is older than other nebulae and was probably a lot smaller. In addition, Horsehead Nebula is farther away from the Earth than other nebulae, so it may seem that it doesn't glow as bright as other nebulae. No, this isn't right! The horsehead nebula doesn't glow for one reason - it isn't illuminated by any stars whose energy is enough to make the gas shine. That's the only difference between a 'bright' diffuse nebula (like M42) and a 'dark' one like the Horsehead or the Coalsack. M42 (the Orion nebula) is bright because there are several hot, energetic stars embedded inside it, and which cause it to 'shine'.
