For the first time, determine the 3D structure of the nebula

NASA scientists used the Hubble astronomical telescope to determine the 3D structure of the Ring Nebula. Thereby, its structure is shaped like a frozen donut located in deep space.

The latest images of the Nebula allow scientists to observe in the most detailed way that no space telescope has ever been possible.

Mr. C. Robert O'Dell - an astronomer at Vanderbilt University, Nashville, Tenn., Who is also the head of the study - said: 'The shape of the Nebula Ring is not the same as the previous research. , it's more like a frozen donut because the middle of the nebula is filled with matter. "

The Nebula is a gas shell that explodes from a dying star, 2,000 light-years from Earth, in the constellation Lyra and about a light-year across. This nebula formed 4,000 years ago and is the second nebula that humans have ever discovered.

Scientists further explained this star after enlarging to form a giant red space, beginning to spread the gas layers far away, then bursting and becoming white dwarfs. The star will emit intense ultraviolet light that burns the surrounding air and creates bright light.

In addition, the scientists were stunned to discover the unusual knots of the dark universe with a dense amount of gas along the edge of the nebula. The speed of the Ring Nebula reaches 69,200 km / hour and it will continue like that for the next 10,000 years.

By studying nebulae, scientists hope to better understand the Earth's Sun, which will die for 6 billion years.
