NASA/ESA Hubble Space Telescope Takes Shot of NGC 5307

The image from the NASA/ESA Hubble Space Telescope shows NGC 5307 – a planetary nebula that thrives about 10,000 light-years from Earth. It may be seen within the constellation Centaurus (The Centaur), which might be recognized primarily in the southern hemisphere of the cosmos.

A planetary nebula is the final or end-stage of its life in the type of a Sun-like star. As such, planetary nebulas allow us perception into the future of our solar system.

A star like our Sun will, on the finish of its life, rework into a red giant. Stars are sustained by nuclear fusion that happens of their core, which creates energy.

The nuclear fusion processes continuously attempt to rip the star aside. That’s, the gravity of the star, hinders this from taking place.

On the finish of the large red section of a star, these forces turn out to be unbalanced. Without the necessary energy created by fusion, the core of the star collapses with itself – whereas the surface layers are ejected outward. After that, all that is still of the star is what we see in this stage of the planetary nebula: glowing outer layers surrounding a white dwarf star, the remainders of the red giant star’s core.

This is not the end of this star’s evolution, although—these outer layers are still moving and cooling. In just some thousand years they will have dissipated, and all that can be left to see is the dimly glowing white dwarf.
