In a telescope lens got planetary nebula NGC 2022.
Astronomers using a telescope “Hubble” has received the planetary nebulae NGC 2022, which resembles a small Medusa or ink blot. In fact, this cloud of gas, which was thrown away a dying star, reported on the website of the Observatory, reports the online edition of the Chronicle.info with reference to zn.ua.
The star itself can be seen in the centre of the nebula. When stars like the Sun are starting to get old, they swell up and thrown into space their outer layers. In total, the star can lose about half its mass, and the ejected material around it forms a cocoon.
At the same time, the core shrinks and heats up, releasing ultraviolet radiation which causes the glow of the surrounding gas.
