Observations combining ground-based data and NASA/ESA Hubble Space Telescope data, however, revealed that it is more like a distorted doughnut 🍩⁠ ⁠ The brightest part of this nebula is what we see as the colourful main ring. This is composed of gas thrown off by a dying star at the centre, which is on its way to becoming a white dwarf.⁠ ⁠ For more information check the link in bio.⁠ ⁠ 📷 NASA, ESA, and C.
