Simeis 147: Supernova Remnant
This supernova remnant has an estimated age of about 40,000 years - meaning light from the massive stellar explosion first reached Earth 40,000 years ago. It is in the direction of Taurus and spans nearly three degrees of the sky (six full moons). Meaning that at a distance of 3,000 lightyears, the width of this debris cloud is about 150 light years wide. The cosmic catastrophe that left behind this remnant also left a pulsar, which is the still spinning core of the original star. The thought of the core still spinning is kind of eerie to me...
