One day our sun will die. And even though it means the fiery end of all of us, or our pure-energy descendants, we can at least take solace in the fact it will be rather pretty.
This video shows the Ring Nebula formed when intense radiation from a dying star heats gas in its outer layers and they escape into space.
New observations of the nebula by the NASA's Hubble Space Telescope have revealed a more complex structure than they had initially thought.
Dr. C. Robert O'Dell, an astronomer at the Vanderbilt University said: "The nebula is not like a bagel, but rather, it's like a jelly doughnut, because it's filled with material in the middle."
"With Hubble's detail, we see a completely different shape than what's been thought about historically for this classic nebula.
"The new Hubble observations show the nebula in much clearer detail, and we see things are not as simple as we previously thought."
The RIng Nebula is around 2,000 light-years from Earth and about 1 light-year across. It is located in the Lyra constellation.Suggest a correction
