Explanation:
What visual effects are depicted in this video?
The effects were created by
BDH for the
BBC television show
Wonders of the Universe,
but are unlabeled in this version.
Even so, some stills in the video are easily identified, such as the
Hubble image of the
Carina Nebula that occurs at about 2:22,
the Crab Nebula at about 7:45, and the
Cat's Eye Nebula that occurs at about 8:16.
A pan away from a spiral galaxy occurs at about 4:00, and breathtaking
vistas of the spiral occur until past 5:00.
Pulsars and supernovas seem to take over
at about 9:00 and are truly spectacular.
Binary star systems containing a pulsar and an
accretion disk occur beginning at about 14:30.
Past that, the entire
computer animated video
seems to sparkle with unknown stars, unknown planets, and
sequences where unknown gas is flowing toward unknown places.
What,
for example, is being depicted at 13:00?
