Pleiades Nebula

[Astrosurf]

I was at my Astronomical Society tonight where the organiser was showing some images. One of them was the Pleiades. I mentioned I had read that the open cluster was simply traveling through the nebulosity and that the nebulosity was not the stars' original stellar nursery. He disagreed and said that the nebulosity was indeed the gas and dust they formed from. Was I wrong??

Sounds like a question for Dr Alan Longstaff of the Magazine (AN or S&N, I can't remember which :? ).

I thought they are a true cluster, ie not a line of sight effect, and they are a group new stars formed from the nebulous gas cloud we can see.

I agree with Adam I thought the nebulosity belonged to the actual stars of the M45.

Your astro adviser is correct Alexx, It was originally thought that the the gas and dust illuminated by the cluster, was left from the formation of the stars.

According to Wilkpedia, it is now established that the cluster is moving through the gas/dust, and there is no other relationship.

Thanks Ron. It's me that's correct. I was the one who said I read there was no relationship! I feel vindicated! Now, do I tell him and risk rubbing him up the wrong way? . . . :shock:

If you have S@N and AN to hand I'm 99% sure this came up in a magazine article about a year ago.

No, I would maintain a dignified silence. That will Irk him some.

Those "I told you so" responses don't work.

Ron.

Oh!, and apologies for misreading your opening post Alexx. :oops:

[Tim]

Yeh, he's bound to check Alex! hehe

[Astrosurf]

Thanks guys!

It's OK Ron, I spend my life topsy-turvy!

[Sam]

a quietly smug smile and the knowledge that you were right is all you need Astrosurf - otherwise people get grumpy

[RobH]

Yep, you're right Alex

I had something similar at our Christmas astro quiz...'what is the brightest star in Orion'?

I said Rigel, but was told I was wrong.

Now I know that Rigel is the brightest, not alpha....Betelgeuse, so I had to check.

Rigel comes in at no 7, Betelgeuse at 10!!!

I didn't maintain a dignified silence

Cheers

OK smart Alex

I stand with many others corrected, unless they change their minds of course.
