This little guy is a planetary nebula in the constellation Taurus, which was discovered by William Herschel in 1790. While he was working on the New General Catalog, he believed that most nebulae were unresolved clusters of stars, but this sight made him re-think that idea.

The star at the center of this planetary nebula is HD 281679, which is actually a binary star. The bright, visible star is not the source of the nebula; rather, its fainter companion, an O-type star, is the one ejecting all its gas. They orbit each other every 4-9 days! The system is about 1,000 lightyears distant.

Planetary nebulae are actually the death throes of, ordinarily, main-sequence stars like our Sun, although the progenitor star here was in its asymptotic giant branch, but mass transfer between the two stars seems to be causing the loss of gas and the outward expansion. Perhaps this is why it looks more chaotic than other planetary nebulae I'm familiar with!

I created this image by combining hydrogen-alpha (Ha) and oxygen-III (OIII) narrowband data together with the wideband luminance, red, green, and blue data to get a nice combination of detail and brightness as well as color (and good star color). It's a total exposure of nearly 30 hours; one of my longest!
