NASA 4) Butterfly Nebula (NGC 6302) Located in the constellation Scorpius, the structure of this nebula is one of the most fragile and complex that has ever been studied. The butterfly shape has lead scientists to name it's structure a "bipolar structure."
This planetary nebula, Mz3, is being cast off by a star similar to our Sun. The 1000-kilometer per second speed of the expelled gas, the light-year long length of the structure, and the magnetism of the star visible at the nebula's center, all imply Mz3 is hiding a second, dimmer star that orbits close in to the bright star. A competing hypothesis holds that the central star's own spin and magnetic field are channeling the gas. (ESA, NASA's Hubble, JPL-CalTech)
The #SwordOfOrion - The Orion constellation is noticeable for three medium-bright stars in a short, straight row. These stars represent Orion’s Belt. If you look closely, you’ll notice a curved line of stars “hanging” from the three Belt stars. These stars represent Orion’s Sword. Look for the Orion Nebula about midway down in the Sword of Orion, otherwise known as M42, a stellar nursery where new stars are being born.
The Horsehead Nebula is a cloud of ionized-hydrogen in the constellation Orion. These clouds are lit from within by young, hot stars. The interstellar dust absorbs the light from part of the ionized cloud creating this beautiful contrast. Image Credit: NASA, NOAO, ESA and The Hubble Heritage Team (STScI/AURA)
