for over 20 years the Hubble Space
Telescope has given us iconic images of
far away galaxies and has expanded our
understanding of the
[Music]
cosmos it's scheduled to see into space
for the last time this decade and plans
to replace it are taking
off in June we headed out to Battery
Park in Manhattan where a full-scale
model of the next big Space Telescope
was on display at the world Science
Festival they we met Paul gner and I'm
the observatory manager for the James we
Space Telescope program at NAS SC space
flight center he told us about the James
web Space Telescope which will be the
biggest telescope that's ever been put
into space the main mirror is almost 22
ft across and when it comes to the
telescope Size Matters the bigger the
telescope the more you can see so this
is bigger so it can see farther and see
more gner added that the web will be so
sensitive from Earth it could detect a
nightlight on the moon
scientists want to use the web to study
the early Universe they can do that
because light travels at a finite speed
186,000 Mi a second meaning the Rays of
distant stars and galaxies take a very
long time to reach us so often we're
seeing the universe as it was thousands
millions billions of years ago so when
we look deeper into space we're act
we're also looking back in time and when
Hubble sees as far as it can see it sees
a lot of galaxies it sees a chaotic
Universe crowded with galaxies season
and stars um but it doesn't see the very
first ones but we're building this
telescope to go see that see back that
far while the Hubble Is about 350 M over
our heads the web will be sent a million
miles from Earth four times farther away
than the moon in order to see these
ancient galaxies to dispatch it to that
distance gner said Engineers will build
the web's mirror into 18 smaller
hexagons that can fold up into a rocket
it's like a complicated piece of origami
and when it gets into space it's all
going to unfold like like a flower or
like a like a butterfly coming out of
his cocoon set to launch in 2014
scientists plann for the $5 billion web
to operate for at least 5 years but are
putting Enough Rocket Fuel on board with
the hopes it can last up to 10 gner
can't wait to see what it can do if you
like hble Space Telescope I think you'll
love the James web Space Telescope cuz
it really does have the promise to uh
rewrite the textbooks and astronomy and
and things we know about the universe
just like Hubble has that's pretty
exciting to be a part of something like
that
