Explanation:
What if you could go right into a cluster where stars are forming?
A one-minute, time-lapse,
video visualization of just
this has been made with 3D
computer modeling
of the region surrounding the star cluster
Westerlund 2, based on
images from the
Hubble Space Telescope in
visible and
infrared light.
Westerlund 2
spans about 10 light years across and lies about 20,000 light years distant toward
the constellation of the Ship's Keel
(Carina).
As the
illustrative animation
begins, the greater
Gum 29 nebula
fills the screen, with the young cluster of bright stars visible in the center.
Stars zip past you as you approach the cluster.
Soon your
imaginary ship
pivots and you pass over light-year
long pillars
of interstellar gas and dust.
Strong
winds
and radiation from massive young stars destroy all but the densest nearby
dust clumps, leaving these pillars in their
shadows --
many pointing back toward the cluster center.
Last, you pass into the top of the
star cluster and survey hundreds of the
most massive stars known.
