Detailed new images of the starbirth nursery in the Omega Nebula (M17) have revealed a multi component structure in the envelope of dust and gas surrounding a very young star. The stellar newborn, called M17-SO1, has a flaring torus of gas and dust, and thin conical shells of material above and below the torus. Shigeyuki Sako from University of Tokyo and a team of astronomers from the National Astronomical Observatory of Japan, Japan Aeorospace Exploration Agency, Ibaraki University, Purple Mountain Observatory of the Chinese Academy of Sciences, and Chiba University obtained these images and analyzed them in infrared wavelengths in order to understand the mechanics of protoplanetary disk formation around young stars.

The Sun and the solar system formed from a dense cloud of gas and dust similar to M17-SO1 some 4.6 billion years ago. All the material that makes up the Earth and the creatures that live upon it originated in that primordial cloud. Once the Sun formed, its gravity pulled gas and dust inward. When the Sun's gravitational pull and the centrifugal force of the infalling material balanced, the remaining material settled into orbit around the Sun. The resulting disk of gas and dust was a protoplanetary disk. Repeated collisions of gas and dust within this disk led to the formation of the planets. To understand what the early solar system was like, and to understand how planetary systems form in general, astronomers are actively studying stars that could be similar to the Sun as it was 4.6 billion years ago.
The observations regarding this planetary envelope can be substantial in extending our understanding of the proto-disk that once surrounded our Sun.

where did this cloud originate from, a part of another star?
any link on how stars are born?
and omega nebula is another galaxy?
and perhaps unrelated, are stars , galaxies, in different planes are same planes? and if in different planes, would we see a different sky from a telescope in south pole compared with a telescope in north pole (do i make sense:(? )
btw strugglin with that code. i wanted only the part on displayin the 5 main ids, who comments (other than annons) and the post number count.
i think i found the segment on comments, but couldnt incorporate. i dont want to be lazy and ask for readymade, so i will work on it for a week and then ask u if i cant:) thanks for that file:)
For how stars are born, check here.
Omega Nebula (or Swan Nebula, M17) is 5000 light-years away, and is a active star-forming region in our Milky Way galaxy.
The milky way galaxy is a flat, spiral galaxy. So most of its stars are in a plane. But the rest of the galaxies (and there are 100 billion of them!) lie everywhere in th sky. And we do see different views from different places on Earth, for example, the North Star is only visible from the Northern Hemisphere.
Sailing is not a race, it's about relaxation. Just gliding along, seeing the sights, being one with the universe.
