NEXT ON NOVA: "RUNAWAY UNIVERSE"
http://www.pbs.org/nova/universe/
Broadcast: April 8, 2003
(NOVA airs Tuesdays on PBS at 8 p.m. Check your local listings as
dates and times may vary.)
NOVA presents an exploration of quintessence -- the mysterious repulsive
force that some scientists believe counteracts gravity. The program
follows the efforts of two rival teams of astronomers as they search for
exploding stars, map out cosmic patterns of galaxies, and grapple with
the ultimate question: What is the fate of the universe?
Here's what you'll find online:
History of the Universe
This interactive timeline reveals the evolution of the universe from
the Big Bang to the time when burned-out stars and black holes will
have evaporated.
Birth of a Supernova
What happens when a star explodes? This interactive feature
demonstrates, step-by-step, the sequence of events that results in
Type Ia and Type II supernovae.
Tour the Universe (VRML)
This VRML feature allows you to take an extensive tour of our
local universe. Within this three-dimensional world, you can visit
and learn about 2,000 of the galaxies that surround our own.
Moving Targets
Find out how astronomers use the Doppler effect and redshift to
determine how fast a stellar object is moving away from or toward
the Earth.
How Big is the Universe?
Cosmologist Brent Tully attempts to answer this question while
discussing some of astronomy's latest developments.
Spin a Spiral Galaxy (QTVRs)
Among severa QTVRs in this feature is an object VR that allows you
to spin a spiral galaxy, revealing how a galaxy can appear to be
elliptical, round, or flat in shape, depending on your vantage
point.
NOVA News Minute (available April 7)
Einstein once called his "cosmological constant" the greatest
blunder of his career. Could it turn out to be valid after all?
This video clip explores the answer.
