- astatine, on 10/12/2007, -3/+23Typical geeks - they give 'em a shiny new telescope, the first thing they go looking for is green-skinned slave girls.
- jamessavik, on 10/12/2007, -0/+15Orion is one of the most studied patches of the sky. It has a little bit of everything: blue and red supergiants, OB associations, reflection and emission nebula, protostars, ZAMS, Herbig-Haro objects, stellar disks and so on.
- 4degrees, on 10/12/2007, -0/+11does that also mean solar panels and solar cells will only work in this star system?
- xemvip, on 10/12/2007, -2/+12I thought we had the only "Solar" system, our sun being called "Sol" and all. I thought all other systems would be "Planetary Systems"?
Oh well, I can't even afford a plane ticket across the country, I won't be visiting Orion anytime soon. Probably can't take my shampoo on that flight either. =P - inactive, on 10/12/2007, -1/+9Wow. I would have been satisfied with "it's got lots of stars."
- talyesin, on 10/12/2007, -2/+7pedantic geeks also sound like morons, even if they are correct!
- BitSlash, on 10/12/2007, -0/+4No, solar cells only work here. Photoelectric cells work anywhere. :p
- zadadka, on 10/12/2007, -2/+6...and you don't sound condescending when you say it right?
- Mworthin, on 10/12/2007, -2/+4You have forgotten the solar plexis, you numbskull!
- inactive, on 10/12/2007, -1/+3So tell that to the scientists who identified the 2300 possible "Solar" Systems.
- BitSlash, on 10/12/2007, -0/+2True, should be referred to as star system or planetary system. Our star system is called the Solar system.
- rodrigo74, on 10/12/2007, -1/+3"My God, it's full of stars!"
- inactive, on 10/12/2007, -0/+1I would imagine that their solar wind would have something to do with it as well.
Don't quote me on that. - jamessavik, on 10/12/2007, -0/+1>what is the force driving these stars apart? Maybe i don't quite understand just how large this nebula is, but it couldn't be as big as a galaxy and is obviously bigger than a typical solar system.
Stars form in many different ways but when they form in tight grouping like we see in Orion, they are called clusters. In some clusters, gravity acts to hold the stars together tightly. In other clusters, differential gravitational forces act to eject some stars or even tear the cluster apart.
If you look at distant spiral galaxies, the "arms" of the galaxies are usually quite bright because they tend to be areas of active star formation (also called starburst). It is thought that as the arms of the galaxy spin around the center, those arms create density waves that act to compress interstellar gas and trigger large scale star formation. If you are curious about this, it's called Density-wave theory first proposed in the sixties by Lin Shu. The Orion Arm is one of these formations. - 4degrees, on 10/12/2007, -0/+1"Newborn stars like the ones in Orion tend to drift away from their siblings over time, so it is hard to trace an adult star's origins."
I wonder; what is the force driving these stars apart? Maybe i don't quite understand just how large this nebula is, but it couldn't be as big as a galaxy and is obviously bigger than a typical solar system. I would think that the gravitation among the stars in the nebula would hold them together. the nebula doesn't look like its spinning.
do these newborn stars(systems) attract each other at first, dance a bit and eventually throw each other out? - Mworthin, on 10/12/2007, -4/+5Green-skinned slave girls are good!
- dinobot, on 10/12/2007, -1/+1The galaxy is in Orion's... belt... *dies*
- techgnostic, on 10/12/2007, -0/+0Interesting debate, I suppose. It seems that there is no consensus on whether or not it is OUR collection of star/planets or ANY collection of star/planets.
http://www.google.com/search?q=define%3A+solar+system
Although, the "almighty" Wikipedia defines it as OUR collection. - pastasauce, on 10/12/2007, -3/+1No, some people are just retarded when it comes to naming things.
- greymaxcat, on 10/12/2007, -15/+3OK People... there is only one (1) "Solar" System... and we live in it. Our star is named "Sol" thus Solar System.... all the others are "Star" Systems.. You sound like a moron when you say it wrong.
