Description

* Image acquisition: Liverpool Telescope
* Processing: Ruben barbosa

NGC 6781 is a planetary nebula located in the constellation Aquila.

This ring-like nebula consists of glowing gas cast off by a dying star some 3,100 light years away.

The nebula has about 2 light years and a faint magnitude 11,4.

With a 12″ telescope, the nebula looks like a ghost image of the Moon. It presents a beautiful spherical shell which brightens towards the edge and a ring around the circumference. The central star, a mid-sized star like our Sun, is throwing off the outer layers of its atmosphere in a last gasp of life.

The nebula will dissipate over the next many thousands of years, and the central star will remain as a white dwarf, a hot glowing cinder which will cool slowly over billions of years.
