Planetary Nebula M57 or the Ring Nebula, is located about 2 thousand light-years from Earth in the constellation Lyra. If you look at the ring from the Earth, the nebula resembles an ellipse, but detailed observations showed that in fact it is more like a twisted donut.
Astronomers working with the Space Telescope "Hubble", received the most detailed ever information on the Ring Nebula and built a 3D-model of it - the famous nebula appeared like a donut curve, according to a statement on the website of the telescope.
Planetary Nebula M 57, or the Ring Nebula, is located about 2 thousand light-years from Earth in the constellation Lyra. It was accidentally discovered by the French astronomer Antoine Darquier de Pelepua in 1779, who tried to trace the path of the comet through the constellation. One of the most recognizable and beautiful nebulae formed gradually "die" a star in its center.
According to the report, if you look at the ring from the Earth, the nebula resembles an ellipse, but detailed observations using a telescope "Hubble" and ground instruments have shown that in fact it is more like a twisted donut.
"We are looking at almost exactly on one of the poles of the complex structure ... Although the center of" donut "looks empty, in fact, he is filled with low-density material, which forms a structure similar to a rugby ball inserted in the donut" - said in a statement.
