The HubbleSpace Telescope

Background on Telescopes:"Tele" is Greek for "far off",and "Scope" is Greek for "look at", so...."Telescope" means "Look at something far off".~The reason we know how large space is is because of the invention of the telescope. Scientists have been using them for hundreds of years!

This all started because of an astronomer named....

Galileo Galilei!

Named after American astronomer, Edwin Hubble, it sent us the 1st clear images of objects in outerspace... billions of miles away!

The Hubble:Launched in 1990 from the USA, the HST was the 1st space telescope.

Billions of galaxies out there!!!

The Latest News with Edwin Hubble

Fast Facts:**The exploration is still in space, due to astronauts being sent into space to give it a tune-up to repair and replace equipment. NASA has saved billions of dollars by doing this!**The Hubble doesn't travel to stars, planets, or galaxies. It orbits the Earth at 17,500 mph taking pictures of them!

Advances that Have Been Made?-Hubble divulged the age of the universe to be about 13 to 14 billion years old, which is much more accurate than the range of 10 to 20 billion years. This awoke a lot of curiosity and wonder amongst scientists....

....which lead them to discover and understand many things, such as dark energy*, and how galaxies are formed, with the help of Hubble, of course.*Dark energy is a mysterious force that makes the universe grow faster.

How is this data collected?-Solar arrays=gather sunlight which turns into electricity. (Power source)-Antennas=send data to Earth.-Reaction wheels & Fine guidance sensors=control & keep telescope focused on target.-Aperture Door=opens and closes to control the amount of light entering.-Mirrors=reflect light through the telescope allowing it to take pictures.-Spectrograph=separates light from cosmos* into colors. (Like a prism.)*The universe seen as a well-ordered whole. ( range of view, allowing to take better images. Installed in March 2002.

Key Dates:1969-NASA starts planning design for 1st space telescope.1975-European Space Agency joined project.1977-Construction begins.1985-Named 'Hubble Space Telescope' after Edwin Hubble.1990- Launched from USA.

Hope you've enjoyed! :)
