The Orion Nebula (Messier 42) is the nearest star-forming region to Earth. It is located in the Orion Constellation, just below Orion's Belt.
Nebula, any of the various tenuous clouds of gas and dust that occur in interstellar space. The term was formerly applied to any object outside the solar system that had a diffuse appearance rather than a pointlike image, as in the case of a star. This d
There is still not a consensus on the cause of the wide variety of shapes. However, astronomers have proposed stellar winds and the presence of other astronomical bodies as potential causes.

They are dense, dim, stellar corpses — the last observable stage of evolution for low- and medium-mass stars. Whilst most massive stars will eventually go supernova, a low or medium mass star with a mass less than about 8 times the mass of the sun will eventually become a white ...
Star birth can take millions of years and create families of stars. Astronomers see examples of star formation in nebulae throughout our own Milky Way Galaxy and in many other galaxies. The most famous and closest stellar nursery to Earth is the Orion Nebula, which lies about 1,500 light-ye...
The wingspan of the nebula, from one to the other, is three light-years. To give you some scale, they would cover three-quarters the distance from here to Rigil Kentaurus, a star better known as Alpha Centauri, our closest stellar neighbour. N.A.S.A. The Butterfly Nebula's distance ...

Eagle NebulaA stellar nursery in the Eagle Nebula (M16, NGC 6611). This detail of a composite image taken by the Earth-orbiting Hubble Space Telescope reveals a glowing column of dust and cold gas populated by embryonic stars forming from molecular hydrogen within the column.(more) 2 of 2 ...
Planetary Nebula, death stage of a stage not massive enough to explode in a supernova Nova is a brightening of a star typically in a binary star system where one of the stars is a White Dwarf, and the other is a Main Sequence Star. ...
The Eagle Nebula is a large cloud of gas and dust where new stars are born. When you take a look at the wispy glow of this nebula through an astronomical telescope orbinoculars, you are witnessing a stellar object that is approximately7000 light-yearsaway. ...
