Great photo Mike and Trish. I see a rodeo rider on a bull (instead of fat opera singer) Cheers, Richard

Ta, Richard. Yes, the bovines are busy either way. (Here, at the farm, it is raining torrentially - excellent - and there are seven cows and two newborn calves within 10 metres of the windowsill).

Best,
Mike

Awesome image M&T

Now I really want to have a go at this area myself!...have 2 weeks of holidays, maybe we will get a few clear nights...

Mike and Trish,

Your image shows good resolution of the massive & compact Young cluster NGC 3603, which is one of the most extreme Young star clusters known in our own Galaxy , at some 10,000 solar masses.



These sorts of Massive Compact Young clusters may have a similar central concentration and density-falloff to standard 'old' globular clusters.
They are often more like young globulars in appearance than open star clusters.

Me and Dana discussed NGC 3603 and other similar young "globular-like clusters" in this science forum thread:

Another extreme young star cluster is Trumpler 14:

Thanks for yet another great image MnT. The covered wagon with our voluptuous opera singer is certainly present. Great technical details as well.

Thanks, Suavi, that's encouraging. Good luck with the weather up there.

Hi, Robert,

I read your link but sadly it was over my head. I've read say Bally and Reipurth, "The birth of stars and planets", and more recently Jones, Lambourne, and Serjeant, "An introduction to Galaxies and Cosmology", where the dynamics of this area got a special mention. Other vaguely relevant books I've read include Kaler's "Extreme Stars", Philips et al "The Physics of Stars, Green Jones et al, "An Intro to the Sun and Stars", and half a dozen similar books, so I know what the words mean one at a time, but you're well ahead of me in synthesising it, or putting it all together.

Are you saying that this cluster is extreme because it has so much total mass?

Is it also extreme because there is a lot of stellar wind and SNR activity? I don't see much evidence for that in the image but perhaps that is because the cluster is very young. Can you talk about that aspect?

You mentioned how it has a density distribution similar to old globulars, but then you go on to say it could be a young globular. Would love to know more. Do you think that this particular cluster could be a captured nucleus or part thereof from a dwarf galaxy?

Best,
Mike

Cheers, Rodney, that's kind.

Very best,

Stunning and fascinating, Mike and Trish. Another example of a 'can't-take-my-eyes-of-it' image with spectacular detail. Wow!

Cheers,
Richard

Thanks, Richard, that's very heartening.

Hi Mike,

An amazing photo.

Great detail. So sharp.

I love the composition.

Ross.

[Pharian (Christopher)]

Wow.

I want a spaceship.

Thanks muchly Ross.
Nice to hear from Cherrybrook, too.

Thanks, Christopher.

A spaceship could be very useful. I've taken the phasers and photon torpedoes off mine, and put them on the Subaru, to deal with tailgaters.

that is a cracking good image. I like the palette and the emphasis on the left hand new cluster region is interesting as well - so many new stars bursting into life from the molecular cloud is breathtaking.

Thanks Ray, that's encouraging. Hadn't really thought about just how many stars there are in that cluster. Thanks for pointing that out.

Best,
Mike

I love this a lot, there is so much variation and detail in all the various parts of the amazingly big target.

Thanks muchly, Dylan. We agree that it's a very narratogenic target - it wants to tell a story, and does much of the work for you.
