THE HUBBLE-SPACE-TELESCOPE
MAIN INFORMATION
• Size
• Length: 43.5 ft (13.2 m)
• Weight: 24,500 lb (11,110 kg)
• Maximum Diameter: 14 ft (4.2 m)
o Hubble´s name:
• Named after Erwin Hubble (1889—1953)
• confirmed an "expanding" universe
=> Provided the foundation for the Big Bang theory.o Speed:
• 28000 km/h
• => 97 min to complete one orbit
HISTORY
Who had the idea to built a space telescope?• It was Lyman Spitzer (1914-1997)
• In 1946 Spitzer proposed the development of a large, space-based telescope
Start of the telescope• on 24th April, 1990
• Difficulties at the beginning
• Pictures were blurry
Þ because Hubble's primary mirror had a flaw called "spherical aberration”
• On December 2, 1993 astronauts corrected the mistake
HISTORY
End of the telescop• It was planned for the year 2010
• But maintance works was rescheduled
=> Now end of the telescope probably in 2014
• Successor of the Hubble space telescope : James Webb Space Telescope

instruments in the hubble space telescopeFor example:
Wide field camera 3• Installed 2009 • Made for natural light
Space Telescope Imaging Spectrograph• acts somewhat like a prism• separating light from the cosmos into its component colors
Signature of a super massive black hole in the centre of galaxy M84A mountain of dust and gas rising
in the Carina Nebula
CONSTRUCTIONcover
Here : Data transmission
For example: antennas for the communication
JOBSFor example:
• Observation of cepheides
RESULTS OF THE TELESCOPE
The Hubble Deep Field• image of a small region in the constellation Ursa Major• Picture was taken between December 18 and December 28, 1995
For example:
Several colliding galaxies
