I've never had trouble seeing the swan in photos.

Could you help me see what you're talking about by giving some pointers of where, in the nebula to find one or more of the O-type stars?

The Omega Nebula is between 5,000 and 6,000 light-years from Earth and it spans some 15 light-years in diameter. The cloud of interstellar matter of which this nebula is a part is roughly 40 light-years in diameter and has a mass of 30,000 solar masses.[3] The total mass of the Omega Nebula is an estimated 800 solar masses.[4]

It is considered one of the brightest and most massive star-forming regions of our galaxy.[3] Its local geometry is similar to the Orion Nebula except that it is viewed edge-on rather than face-on.[5]

The open cluster NGC 6618 lies embedded in the nebulosity and causes the gases of the nebula to shine due to radiation from these hot, young stars; however, the actual number of stars in the nebula is much higher - up to 800, 100 of spectral type earlier than B9, and 9 of spectral type O, plus over a thousand stars in formation on its outer regions.[3] It is also one of the youngest clusters known, with an age of just 1 million years.[6]

The luminous blue variable HD 168607, located in the south-east part of the Omega nebula, is generally assumed to be associated with it; its close neighbor, the blue hypergiant HD 168625, may be too.

Never mind.

On Tuesday, February 27th, Mark Messier's #11 banner will rise to the top of Rexall Place, to take its place alongside a number of other Oilers greats. In addition to the jersey retirement ceremony, prior to the Oilers sold-out game versus the Phoenix Coyotes, a number of other events will be scheduled to commemorate Mark Messier's stellar career.



"I was born and raised in Edmonton, and spent the first twelve years of my NHL career playing for the Oilers. Having my number raised to the rafters of Rexall Place, where we accomplished so much as a team, and I made so many lifelong friends, is truly an honour," said Mark Messier. "For me, the celebration is really about my teammates, the coaches, the fans, and the people of Edmonton that made my days with the Oilers so special. So, as part of the celebration, it was important for me to be able to give something backoto the fans and the community that helped me become the player and the person I am today. By raising a substantial amount of money for local charities, we're going to do just that."

Mark Messier now becomes the 4th hockey player whose name I have ever learned. Ever. And there's no guarantee that I'll remember his first name tomorrow.

4 ?? You're one ahead of me. Besides Mark, i only remember Bobby Orr and Wayne Gretsky, IF i spelled it right. Ah, "Pucknut", big hockey fan. I just got it and it's 1:00 am! A time when a lot of people are probably out looking through a tube at a mess of Messier's scattered about the great galaxy rink in the sky.
