This is the Tadpole Nebula. You can see the hot young stars in the center, which are yellow and look like tadpoles. The faint green line near the top is actually a streaking satellite (one of ours) :)

Simeis 147 (Spaghetti Nebula, or Sharpless 2-240) is a large supernova remnant in the constellations of Taurus and Auriga. It's a result of supernova explosion about 40 000 years ago. This nebula covers about 3° and is approximately 3000 light years away which means that the real size is about 140 light years.
