N 81 Massive and caused the last of the stars inside N 81 are losing their matter by sending a strong stellar wind. Send numerous shock waves and a strong stream of wysokonaładowanych particles, thus boring a wonderful cocoon within the surrounding nebula. The two most radiant stars visible in the photograph form a closed pair near the center of N 81 They send a powerful stream of ultraviolet radiation and cause strong fluorescent glow of the nebula, they illuminate about 300,000 times brighter - each of them - than our Sun. Outdoor hot and glowing gas is cold material, consisting of dust and hydrogen gas. Under normal conditions, the material is completely invisible, but in the photo you can see some of this material on the background of the nebula in the form of long fibers like dust and formed a small, elliptical node. Astronomers believe that these young stars formed from cold matter through gravitational interactions. Nebula N 81 is located in the Small Magellanic Cloud and away from our galaxy at about 200 thousand light years. Source: nasa.gov
