Hi all!

I found this article in my travels and thought it might be of some interest....

Cheers,

Should be in the Science Forum ??

Wow! Mario that certainly is a beautiful, yet strange and haunting looking object. It's a pity they aren't going to be spending much time on it at this stage in trying to work out why it's casting that light.

Where are you Carl? :question: I Would love to hear your input. Or for that matter, anyone that has some knowledge in this area.

Fascinating! Thank you for posting Mario. :thumbsup:

I'm with Craig, I think this should be moved into the science section.

Hi Suzy;
Nice to meet you.

Carl ran away today after I said he should go back to his assignments. (We were both getting way too cheeky)!
He hasn't been since since !
Ie: M.I.A. (missing in action).
:)
Cheers

:lol::lol:

Hi Craig and thank you. So nice (and my pleasure) to meet you as well. ;):)

A quick spin into my costume, a jump into my invisible plane, and a golden lasso will surely retrieve Carl.:D If not, I'll just have to see how far my whistle carries..:help:

Not sure if anyone can elaborate on why the light is this way. See following link:

(Nice photo of it, also).

More detailed explanation of the star, ('bullet'), which they think disrupted the matter, go to:

Very similar to our conversation today on the Science Forum about Hyper Velocity Stars. What we're seeing in this one seems to be what happens to normal matter when one of these bullets ploughs thru a bunch of stuff.

Cheers & Rgds.

[CraigS]

Thanks Paul.

Mind you, Hyper Velocity Stars move at much greater speeds and are theorised to have a different ejection mechanism (or impulse).

From the post the other day (for comparative purposes):

RX J0822-4300, often referred to as a "Cosmic Cannonball = 723 km/sec;
Stars which make bullet-nosed bowshocks in nebulae = around 50 km/sec;
Typical 'young star' velocity = about 10 km/sec;
Light Speed = 300,000 km/sec.

Cheers

Thanks Craig for all that info.:thumbsup:
I didn't know this kind of star existed- very interesting. I have some reading to do! :D
