APOD 2.4

This picture of the Crab Nebula was made Astronomy Picture of the day on November 21, 2014. Also known as M11 and present in the constellation Scutum, the Crab Nebula is actually a remnant of a supernova. Recorded in 1054 by astronomers around the globe, the supernova that created the Crab Nebula was said to be brighter than the full moon, and lasted for upwards of 3 weeks in the sky. The Crab Nebula is roughly 12 lightyears wide and is another 6000 from the constellation, Taurus.

APOD 2.3

This picture of the Cat's Eye Nebula was made Astronomy Picture of the Day on November 9, 2014. A planetary nebula located 3000 lightyears from Earth, the nebula is going into its final phases as a galaxy. Regular convulsions by the nebula's central star create the halo effect, foreshadowing, possibly, the future of our own star.
