The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image. The high-energy radiation from these stars is sculpting the nebula’s wall by slowly eroding it away.
NGC 2035 (also known as ESO 56-EN161 and the Dragon's Head Nebula) is an emission nebula and a H II region in the Dorado constellation and part of the Large Magellanic Cloud. [2] It was discovered by James Dunlop on August 3, 1826.
Minkowski 2-9, abbreviated M2-9 (also known as Minkowski's Butterfly, Twin Jet Nebula, the Wings of a Butterfly Nebula, or just Butterfly Nebula) is a planetary nebula that was discovered by Rudolph Minkowski in 1947. It is located about 2,100 light-years away from Earth in the direction of the constellation Ophiuchus.
NGC 2440 is a planetary nebula, one of many in our galaxy. Its central star, HD 62166, [1] is possibly the hottest known white dwarf, about 400,000°F(200,000°C). The nebula is situated in the constellation Puppis. It was discovered by William Herschel on March 4, 1790. He described it as "a beautiful planetary nebula of a considerable degree ...
NGC 6826 (also known as Caldwell 15) is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "Blinking Planetary", although many other nebulae exhibit such "blinking". When viewed through a small telescope, the brightness of the central star overwhelms the eye when viewed directly, obscuring the surrounding ...
NGC 6357 is a diffuse nebula near NGC 6334 in the constellation Scorpius.The nebula contains many proto-stars shielded by dark discs of gas, and young stars wrapped in expanding "cocoons" or expanding gases surrounding these small stars.
The Wreath Nebula (also known as Barnard 3 or IRAS Ring G159.6-18.5 is an emission nebula and H II region with a radius of about 22 light-years, located about 1,000 light-years away within the Milky Way in the Perseus molecular cloud complex, near the boundary with the constellation of Taurus.
These high-energy stellar winds blow stellar wind bubbles. In planetary nebula NGC 6565, a cloud of gas was ejected from the star after strong stellar winds. [8] G-type stars like the Sun have a wind driven by their hot, magnetized corona. The Sun's wind is called the solar wind.
