It's about 1500 light years away from Earth in the direction of the constellation Taurus. </p><p>Planetary nebulae occur toward the end of the lives of <a href="https://astrodon.social/tags/stars" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>stars</span></a> that have about the mass of the Sun. They shed their outer layers into space, leaving behind an Earth-sized star called a white dwarf. Its temperature can be up to about 100,000 degrees, so it emits a lot of ultraviolet and X-ray light. That light energizes the gas ejected during the earlier phase, lighting it up like a neon sign. (NGC 1514's white dwarf is the bright star at the center with the spikes, which are an artifact of the telescope's optics.)</p><p>This image is a composite of individual frames made through three colored filters by the Webb telescope's Mid-Infrared Instrument (MIRI). The image shows two concentric shells of material whose bright edges appear as circles. It's actually an hourglass-shaped structure seen an angle inclined to our line of sight toward NGC 1514.</p><p>A newly published study finds that these rings are different than the reddish material inside them. The light they emit comes from very tiny grains of carbon-rich material given off by the progenitor star very late in its life. </p><p>But why the ring shapes? It turns out that the progenitor star was actually two, only one of which endured this phase of high mass loss. Energetic "winds" given off by the stellar pair shaped the carbon grains as they were pushed away from the system. </p><p>(Processing of this image was done by Judy Schmidt: <a href="https://www.flickr.com/photos/geckzilla/54206737999" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">flickr.com/photos/geckzilla/54</span><span class="invisible">206737999</span></a>)</p><p><a href="https://astrodon.social/tags/Astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Astronomy</span></a></p>
