December 1, 2014: Strange Planetary Nebula Adam Block/Mount Lemmon SkyCenter/University of Arizona
WeBo 1 is a strange planetary nebula (dying star) that was discovered in the mid-1900s. Although an interesting curiosity to astronomers, no high-resolution color images have been taken of it... until now.
It is a tiny, faint and very cool object. The discoverers (that recognized its true nature) wrote a readable astronomical journal article about it here.
I just love the nearly perfect oval glow amidst a sea of stars and nebulae.
