Une visualisation immersive du Centre Galactique
What if you could look out from the center of our Galaxy -- what might you see?
Two scientifically-determined possibilities are shown in the
featured video,
an immersive 360-degree view which allows you to look around in every direction.
The pictured computer simulation is based on
infrared data
from ESO's
Very Large Telescope in
Chile and
X-ray data from
NASA's orbiting
Chandra X-ray Observatory.
As the video starts, you
quickly approach
Sgr A*, the
supermassive black hole in the
Galactic center.
Then looking out,
this 500-year time-lapse simulation
shows glowing gas and many points of light orbiting all around you.
Many of these points are young
Wolf-Rayet stars
that have visible hot winds blowing out into surrounding nebulas.
Clouds approaching close become elongated, while objects approaching
too close fall in.
Toward the video's end the
simulation repeats, but this time with the dynamic region surrounding
Sgr A* expelling hot gas that
pushes back against approaching material.
