space tools

space hubble

• NASA named the world's first space-based optical telescope after American astronomer Edwin P. Hubble
• April 24, 1990 from space shuttle Discovery.
• Hubble transmits about 120 gigabytes of science data every week.
• Hubble must be extremely steady and accurate.
• Hubble is a telescope that orbits Earth.

space shuttle

• After 30 years of service, NASA's fleet of three space shuttles is standing down for good.
• The space shuttle program sent over 3 million pounds of cargo into space.
• The space shuttle was 184 feet long.
• The liftoff weight of the space shuttle was 4.5 million pounds.
• For an entire generation, the space shuttle was NASA.

planetarium

• The planetarium is built on what once was an artificial island on Lake Michigan. 
• The term “planetarium” was initially used to represent a small model of the solar system. 
• In October 2013, the Planetarium re-opened after a 16-month renovation process. 
• Two of the shows offered by the Planetarium during Fall 2013 are The Autumn Sky and Oasis in Space. 
•  the Planetarium’s goal is to show visitors some of the amazing discoveries that have been made

Binoculars

• Early telescopic lenses were full of bubbles and other imperfections.
• Early binocular models had brass housing covers and were relatively heavy and expensive to produce. 
• If you didn't know that Binoculars continue to advance with new technology.
• Binoculars are also coming equipped with night scope vision. 
• Early binoculars were actually called binocular telescopes.

telescope

• The first telescopes were all refracting telescopes.
• The first telescopes were made using glass lenses.
• Modern telescopes can detect infrared and radio waves.
• The reflecting telescope was invented by Isaac Newton.
• An observatory is a remote location that houses at least one telescope.

space radio

• Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies
• Radio astronomy is conducted using large radio antennas referred to as radio telescopes
• The use of interferometry allows radio astronomy to achieve high angular resolution
• Radio astronomers use different techniques to observe objects in the radio spectrum.
• Radio telescopes may need to be extremely large in order to receive signals with high signal-to-noise ratio
