Astronomy / Space Nebulae in 3D

To celebrate our new Astronomy sub-forum I thought I'd share with you something that was emailed around the offices this morning at Frontier; a bunch of gifs that show nebulea in 3D, by using a parallax effect. Check them out at the following link:

enjoy!

Wow :eek: :eek: :eek:

Really special stuff. Not sure how accurate it really is, but it's damned impressive looking. Looking forward to flying through a few of these in 10 months time :D

Lovely to watch! At the risk of attracting some well deserved abuse for pointing this out, shouldn't that be "nebulae", not "nebulas"?

Looks stunning.

Some older threads have been moved to here as well. Well worth checking them out :D

I'm really impressed about this new astronomy forum.
I might even start posting things again.

woof woof! - That's my other dog impression.

Beautiful images, you've got to love the parallax effect and Earths orbits round our star. Great new sub-forum too! :cool:

I was going to ask, is that how it was done? It's actually real parallax? If so, very impressive indeed.

Cheers,

Drew.

From the linked page:
Finnish astrophotographer J-P Metsavainio has developed a brilliant experimental technique that overcomes this (kinda): he converts astrophotographs into 3D volumetric models, and then uses those models to create dazzling 3D animations of nebulae.

Very good idea to regroup all of astronomy topics in this sub forum. We have a real cavern of Ali Baba on this specific topic. As these nebulae 3D.

Yes, the Earth's orbit around the sun basically acts like a pair of eyes for us, we are able to measure the parallaxes of nearby stars.

String these images together and you have a partial 3D image like that. The more images the better the resolution of the 3D movie there [like a GIF file really].

And whilst on the use of parallax ...

The Hipparcos satellite [An acronym for High Precision Parallax Collecting Satellite] (launched by the European Space Agency in 1989) measured precision parallaxes to an accuracy of about 0.001-arcsec.

  • Hipparcos measured parallaxes for about 100,000 stars
  • Got 10% accuracy distances out to about 100 pc
  • Also got good distances for bright stars out to 1000 pc.

So here's a bit of fun for you, [warning, it my make you go cross eyed.] :)

Also, the Gaia mission is due for launch in October 2013 will be even more precise. It will be doing a three-dimensional map of our Galaxy surveying an unprecedented one per cent of its population of 100 billion stars. Gaia will be able to measure a star's position and motion 200 times more accurately than Hipparcos. Now thats some cool science. :cool:
