The Calabash Nebula, pictured here — which has the technical name OH 231.8+04.2 — is a spectacular example of the death of a low-mass star like the sun. This image taken by the NASA/ESA Hubble Space Telescope shows the star going through a rapid transformation from a red giant to a planetary nebula, during which it blows its outer layers of gas and dust out into the surrounding space. The recently ejected material is spat out in opposite directions with immense speed — the gas shown in…

Helix Nebula. The two light-year diameter shroud of dust and gas around a central white dwarf has long been considered an excellent example of a planetary nebula, representing the final stages in the evolution of a sun-like star

I know it's been months since I've been on @love_for_astronomy, i have been working on a farm, learning new things and making good money. I also have been rebuilding my dream car, and i got so focused on my life, but i miss @love_for_astronomy and want you all to know I'm back and really looking forward to sharing more with my fellow followers! 🌌🌍🌕 To some, it may look like a cat's eye. The alluring Cat's Eye nebula, however, lies three thousand light-years from Earth across interstellar…

Space - Community -   The #HelixNebula is an example of a planetary nebula, or 'planetary' formed at the end of a star's evolution. Gases from the star in the surrounding space appear, from our vantage point, as if we are looking down a helix structure. The remnant central stellar core, known as a planetary nebula nucleus or PNN, is destined to become a white dwarf star. The observed glow of the central star is so energetic that it causes the previously expelled gases to brightly fluoresce.

This composite image shows a planetary nebula, Abell 30, located about 5500 light years from Earth. A planetary nebula is formed in the late stage of the evolution of a sun-like star.  The evolution of A30 stalled and then started up again, so the planetary nebula was reborn, a special, rarely-seen phase of evolution. - Credit: NASA et al

In the constellation Aquarius and about 700 light years from Earth is a planetary nebula called the Helix Nebula or NGC7293. The Helix Nebula is a star in the final stages of its evolution. The remnant central core or planetary nebula nucleus is so energetic that it causes the previously expelled gases to brightly fluoresce. The core will eventually become a white dwarf star. This star can be seen in the image as a point of light in the center of the helix. This is a 3 hour exposure.
