For those not yet introduced to this part of the sky. M97, the Owl Nebula, is a planetary nebula with a small (visible in this image) 16th mag central star that has gone supernova. It has pushed out two lobes of space amongst the shell of gas that make the nebula appear like owl eyes.
In the lower right is a nearly edge-on galaxy, Sc type galaxy and about 45 million light years distant.

- Loving husband, proud father, computer geek, astro freak, music lover, sports nut and general fun-loving guyI've always loved facts, provable facts of nature and things concerning science.Over time, I found that most facts are mostly reference and it was the creation of and discovery of new things that intrigued me."A good friend once told me you are our memorywithout them we equal nothingAnd all I can see is the place I wanna beSuddenly my life was so freeLeaves at my feet, blown to the groundtheir echoes are reaching my earsNights coming fast, suns going down" - A7x
