- Murdats, on 10/10/2008, -0/+9maybe thats because it takes many, many times the human life span.
explosions however are generally much faster. - rlutterb, on 10/10/2008, -0/+4How is star formed? How is star formed? How space get pragnent?
- Specializedone, on 10/10/2008, -0/+2I think what they're trying to say is that we've never witnessed a solar ignition.
- oldman, on 10/10/2008, -0/+2I have seen pictures that describe an area of condensing dust as star forming.. still takes some imagination to see but that's as close as we get.
Maybe someday someone will have a picture of a new star, but then you'd just have two pictures one with a new star one without. (how exciting (NOT)) - TSK05, on 10/10/2008, -0/+2We can't really witness "solar ignition" because protostars are surrounded by an accretion disk (ie, swirling dust and gas) that obscure our view. We could perhaps use longer wavelengths to look through it but even then, when exactly would you say a star is born? Even after it becomes pre-main sequence (which is the general definition of star birth), the accretion disk doesn't disappear overnight. You could say when fusion starts but photons follow random a random walk, meaning that in our sun for example, if fusion stopped today, we wouldn't know for roughly a 100 years because that's how long it takes a photon to get out of the sun. And the star forming regions we see are too far away (because in our own galaxy, the gas and dust of the disk obscures our view) to get data from an individual star being born using neutrons (which don't follow a random walk and pass straight through the star).
- TSK05, on 10/10/2008, -0/+2Woo, it's an HII nebula. Awesome! Just kidding (it's very common) :P. If you're still in college (or plan to come back to one, I saw one or two older people, ie 50s, in my early astronomy for majors courses), take astronomy 100, that course teaches about HII regions and a lot more ;)
- MidazTouch, on 10/10/2008, -0/+2I've always wanted to be an astronomer/cosmologist and I have never seen anything like this picture before. Dugg for small children.
- diggin1T, on 10/10/2008, -0/+1space is truly beautiful.
- gaapgod, on 10/10/2008, -3/+3Hey folks. Gaapgod here. When you make a comment, it usually helps to have something intelligent to say.
- CarStan, on 10/10/2008, -2/+2how is stars formed?
- exeprime, on 10/10/2008, -3/+2Wait. Why aren't the territories of BoB and Goonswarm marked on this map?
- Balzak65, on 10/10/2008, -2/+1According to the article itself, this is a "star forming" region:
"The colourful image offers a fresh look into the history of the star-studded region, called NGC 346, revealing new information on how stars in the Universe form. NGC 346 is the brightest star-forming region in the Small Magellanic Cloud, a dwarf galaxy that orbits the Milky Way, at a distance of 210 000 light-years." - mongo22, on 10/10/2008, -2/+1Good stuff. I'd love to see a star forming. Guess this is the closest I'll get.
- Bezoar7, on 10/10/2008, -3/+1Correct me if I'm wrong, but I don't think anyone has ever actually seen a star form. We have however seen some that have blown up.
- galv0, on 10/10/2008, -5/+2I have similar looking abstract paintings of my potential children splattered all over the wall. Less color.
