Hubble photographed the planetary nebula NGC 3918

In this image of the Hubble telescope, you can see the planetary nebula NGC 3918. It is located in the southern constellation Centauri at a distance of about 4900 light years from Earth.

NGC 3918 was discovered by the English astronomer John Herschel in 1834. It is one of the brightest planetary nebulae of the southern sky. In its center is a dying star. Once it resembled our sun. But then the light exhausted the reserves of hydrogen fuel and began to expand, turning into a red giant. Having reached the final stage of its life cycle, the star began to reset the outer layers of the atmosphere into the surrounding space. The radiation from her exposed nucleus ionized the discarded shell, causing it to glow.
The Hubble image is combined from images taken in the visible and IR part of the spectrum. It demonstrates the complex structure of NGC 3918, with its shape that resembles the eye.According to observational data, the velocity of a substance ejected by a star is about 100 km / s.

The life expectancy of planetary nebulae is usually several tens of thousands of years. By astronomical standards, this is literally a couple of moments. Over time, the core of the star cools down so that it ceases to radiate enough ultraviolet radiation to ionize the gas envelope. As a result, it will become invisible. The core will turn into a white dwarf.
