INTRODUCTION TO HUBBLE
TELESCOPE
Presented by: MR B4JW4

SOME FACTS:
• The Hubble telescope is
named after
astronomer Edwin Hubble
• The Hubble Space
Telescope (often referred
to as HST or Hubble) is a
space telescope that was
launched into low Earth
orbit in 1990 and remains
in operation

SOME FACTS:
• Hubble Space Telescope is
about the size of a large school
bus.
• It weighs 24,500 pounds. That’s
just under two adult male
African bush elephants.

SOME FACTS:
• Hubble gathers
energy from the
sun using two 25-
foot solar panels.
It requires much
less power than
one might think,
averaging 2,100
watts of power
usage. A hair dryer
requires about
1,800 watts.

SOME FACTS:
• Hubble orbits the Earth at a
cruising speed of 17,000 miles
per hour, and takes 15 minutes
to rotate 90 degrees.
• Hubble has observed
locations more than 13.4
billion light years away,
meaning it has seen light that
existed in the universe 13.4
billion years ago.

SOME FACTS:
• Astronomers using
Hubble data have
published more than
13,000 journal
articles, making it
one of the most
productive scientific
instruments ever
built.

Advantages Of Hubble Space Telescope:
• The earth’s atmosphere
• The detail is absolutely extraordinary
• It points to the potential of the space program

Disadvantages Of Hubble Space Telescope:
• Operating in space
• Time consuming
• Expensive
• Repairs are difficult
