Female Voice Over Documentary Narrator - Hubble - Death of the Grande Dame - SUBTITLED

Hubble our beloved telescope is one of the greatest technological achievements in
human history. It has opened our eyes to the heavens, expanded our understanding about
the fate of galaxies and introduced us to new wonders of the universe.
But Hubble was in danger of being lost. The aging telescope was in need of repairs and
upgrading of instruments and equipment. But with the ending of the space shuttle program,
the future looked bleak. You see, Hubble is dependent upon humans from the earth to service
her and to periodically and gently nudge her back up into her orbit in the extremely tenuous
upper atmosphere, an orbit, because of the forces of nature, naturally deteriorates.
The Hubble Space Telescope orbits nearly 400 miles above the earth, circling the globe
every 97 minutes. The 12 ton telescope, as big as a school bus, was falling back to earth.
The shuttle astronauts though, went to Hubble's rescue in 2009, fixed Hubble, and made her
more powerful than ever. It was however, the last service call. But for the time being
she is back with even more new discoveries. Her powerful instruments see it all, soaring
star nurseries where new worlds are made, the violence of exploding stars and has shed a
new light on Black Holes. This is Hubble's fantastic universe. She is the most celebrated
telescope on earth yet has never touched the earth. Hubble has been our key to understanding
the greatest mysteries of the universe. After her repairs were complete, she turned
her instruments toward a giant gas planet called WASP 12b1, discovering proto-planetary
disks, evidence of the first extra solar carbon rich planet orbiting around a sun like ours
some 600 light years from earth, and who was orbiting too close to its star. She presented
to us the optical counterparts of the still mysterious GAMMA RAY BURSTS.
This is Hubbleís first picture of the Eagle Nebula some 6500 light years away where stars
are born. While Hubble helped to define the age of the
universe, she also cast doubt on theories about its future and our own eventual demise. 0:02:54.250,0:03:01.250. The Helix Nebula lies 700 light years away in the constellation Aquaris, The Crab Nebula, the
leftovers of an exploding great star in our own galaxy.
Hubble is giving scientists an exceptional learning experience. Hubble is monitoring
one star in particular, Edda Corrina in the Corrina Nebula, a star with super heated gas
erupting from the surface. Before Hubble there was no conclusive proof
that Black Holes existed at all. To prove this, Hubble was focused on the centers of
galaxies. Hubble saw stars circling around at high speeds, a sure sign of a black hole.
Further evidence of Black Holes comes from Hubbleís incredible images of a mysterious
jet some 5,000 light years long and is piercing the heart of an elliptical galaxy called M-87.
Before Hubble, Black Holes were merely an unproven astronomical theory. The Hubble Space Telescope
has changed that forever. In the summer of 1992, comet Schumacher-Levi
or SL 9, passed too close to Jupiter and was trapped by the planet's gravity and broke
apart into a long single line called the String of Pearls which eventually collided with
Jupiter and Hubble captured it all. A unique legacy of Hubble is the Hubble Deep
Field and Ultra Deep Field images. Hubble's powerful instruments locked onto a single
region of what appeared to be empty space for 10 consecutive days, creating a series
of exposures that would shake the scientific community. What Hubble saw in this seemingly
empty region space was thousands and thousands of galaxies and a new window on the early universe.
The entire history of growth and change in
galaxies and the universe is written in this single image of the Hubble Deep Field.
But what may be Hubble's most astonishing discovery isnít even seen. Something with
so much power, it holds the entire universe together. It is called Dark Matter.
Thanks to Hubble, astronomers have found a way to locate and measure Dark Matter. But even when
scientists added all the dark matter and all the physical matter together, we were still
missing 2/3 of the universe. Again we turned to Hubble for answers. The only answer was
that far from decelerating under the influence of gravity, something was causing the expansion
of the universe to accelerate, an unseen force known as Dark Energy.
But how long will Hubble continue to fly? After nearly 20 years of operation,
Hubble has received its last service call and although data from a refurbished Hubble continues to
bring us new insights like planets being eaten by their star and discoveries about Dark Energy
and Dark Matter, her days are numbered. Hubble celebrated her 20 birthday in April of 2010
and during that time we have learned more about our universe than in the nearly
400 years since Galileo first looked into his simple telescope. Not since Galileo turned
his telescope toward the heavens in 1610 has any event so changed our understanding of
the universe as the deployment of the Hubble Space Telescope...NASA
Eventually the mission will end. On the day that happens, the Hubble Telescope will receive
one last command to shut down and return to earth. The orbiting telescope will burn up
as she comes home, re-enters earthís atmosphere, and crashes into the Pacific Ocean
sometime in 2024. She will not survive to be displayed in the Smithsonian, but she will remain in
our hearts forever. The Grand Dame will die and pass into history
but not before leaving us an incredible legacy and not without the eternal gratitude of the
people of earth for giving us our first glimpse of our truly amazing universe.
