All stars eventually exhaust their nuclear fuel, running out of fusible material. <img alt="" src="https://miro.medium.com/v2/resize:fit:700/0*nTizib1UL9_5sD7b" style="height:415px; width:700px" /> The Egg Nebula, as imaged here by Hubble, is a preplanetary nebula, as its outer layers have not yet been heated to sufficient temperatures by the central, contracting star. Many of the giant stars visible today will evolve into a nebula like this before shedding their outer layers completely and dying in a white dwarf/planetary nebula combination. (<a href="https://commons.wikimedia.org/wiki/File:Egg_Nebula.jpg" rel="noopener ugc nofollow" target="_blank">Credit</a>: NASA and the Hubble Heritage Team (STScI/AURA), Hubble Space Telescope/ACS) <a href="https://medium.com/starts-with-a-bang/jwst-reveals-the-ring-nebula-like-never-before-ebbc3c2cb6">Read More</a>
