Excerpts from Space.com: In the Gemini constellation - This cosmic region is so complicated that when astronomers first turned their attention to it years ago, they recorded two objects there because there is a symmetrical lobed structure visible there. Today, we know that there is only a single object. Still, in deference to older naming conventions, the region is often known as NGC 2371/2 — a combination of the two older names: NGC 2371 and NGC 2372.
Together the two symmetrical lobes form a planetary nebula, which is a term leftover from an older era in astronomy. With some of the first telescopes, when views were very blurry, astronomers spotted some gassy objects that looked a bit like planets. But these objects turned out to not be planetary at all.
Astronomers expect rapid change to occur in this region within the next few thousand years.
