German scientist Hermann Oberth, wrote “Die Rakete zu den Planetenraumen" which included ideas about having a telescope on a rocket, in space.
-
Astronomer Edwin Hubble used the 100-inch hooker telescope on Mount Wilson to discover what’s beyond our Milky Way. Some difficulties did occur, the atmosphere made it hard for Hubble to clearly see the universe.
-
Astrophysicist Lyman Spitzer first thought of the idea of the Hubble Telescope in 1946. He wrote about the benefits of the telescope.
-
Spitzer’s invention of his telescope was approved in 1968 by NASA, because of difficulties, it did not launch until 1990.
-
The European Space Agency started to work with NASA to discuss the plan of the construction of the Hubble Telescope.
-
After the U.S. Congress permitted it’s construction, it was named after Edwin Hubble.
-
The first space telescope was launched on April 24, 1990. It cost about 1.5 billion.
-
On May 20, 1990, the Hubble telescope took its first photo of space.
-
On Hubble’s first launch, it didn’t have enough mirrors. NASA space shuttle Endeavour launched to attempt to fix Hubble’s problems by connecting missing mirrors.
-
In 1995, the Hubble telescope took a picture of Eagle Nebula. The Eagle Nebula is a cloud of interstellar gas and dust 7,000 light-years away from Earth.
-
Space shuttles restored the HST’s gyroscopes and added new instruments.
-
The last space shuttle launched in 2009 to install a new camera, WFC3, spectrograph, and the COS.
-
Kohoutek 4-55 is expanding and burning everything that is surrounding it. When it gets to earth, the star will burn the planet. The Hubble Telescope has given us its first glimpse of the future of what might be the end of world.
-
In 2013, the Hubble Telescope discovered the age of the universe by using Hubble to measure the brightness of Cepheid variable stars. The Cepheid star will not appear as shiny if it is farther away. This gave researchers an easy way to measure how distant its host galaxy is to earth.

The James Webb Space Telescope will start to orbit by 2018. This newer, more expensive, and more powerful telescope will be as big as the size of a tennis court, and its mirrors would be seven times larger the diameter of Hubble’s mirrors.
