Mayall Cannon 18 is the designation for the Hourglass Nebula. The source is a catalog of faint stars. It was the work of Annie Jump Cannon and Margaret W. Mayall during the 1930s and 1940s, based on and expanding the earlier Draper catalog.

Get on the APOD PING list!

We never imagined such things really existed. I mean, you see them on Star Wars as they go warp speed through them.. but to see a REAL one is just amazing. I don't know how I missed this thread all these years, but I'm sure glad we found you!!

Thank you for opening a whole new world to us.

Nitrogen, Hydrogen, Oxygen.

Earth's atmosphere is mostly nitrogen and oxygen, plus some hydrogen and carbon in combination, which upsets some environmentalists greatly, especially nitrogen and carbon combinations with oxygen. This is where it comes from: burnt out stars.

WE are the eyes of the universe.
