Likely not \u2014 because this is a discovery image. Massive stars forge heavy elements in their cores and, after a few million years, end their lives in powerful supernova explosions. These remnants cool relatively quickly and fade, making them difficult to detect. To uncover such faint, previously unknown supernova remnants, a dedicated group of amateur astrophotographers searched through sky surveys for possible supernova remnant candidates. The result: the first-ever image of supernova remnant G115.5+9.1 \u2014 named Scylla by its discoverers\u2014glowing faintly in the constellation of the mythological King of Aethiopia: Cepheus. Emission from hydrogen atoms in the remnant is shown in red, and faint emission from oxygen is shown in hues of blue. Surprisingly, another discovery lurked to the upper right: a faint, previously unknown planetary nebula candidate. In keeping with mythological tradition, it was named Charybdis (Sai 2) \u2014 a nod to the ancient Greek expression &#8220;caught between Scylla and Charybdis&#8221; from Homer\u2019s Odyssey. via NASA <a href=\"https:\/\/apod.nasa.gov\/apod\/ap250609.html\"><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Can you identify this celestial object?
