Explanation:
What would it look like to approach the Bubble Nebula?
Blown by the
wind
and radiation from a massive star,
this bubble now spans seven
light-years
in diameter.
The hot star inside is thousands of times more luminous than our Sun,
and is now offset from the nebula's center.
The visualization
starts with a direct approach toward the
Bubble Nebula (NGC 7635)
and then moves around the nebula while continuing the approach.
The featured time-lapse visualization is extrapolated from images with the orbiting
Hubble Space Telescope and the
WIYN telescope on
Kitt Peak in
Arizona,
USA.
The 3D-computer model on which this visualization is based includes
artistic interpretations,
and distances are
significantly compressed.
