Wavelength Range for Microwaves

30 centimeters to 1 millimeter

Short Video: This describes where the waves are in the EM spectrum and gives some examples of things that use microwaves.

Electromagnetic Spectrum: Microwaves


Long Video: This video goes into a lot of depth into astronomy specifically. But explains microwaves throughout the video.

New Technology

The Allen Telescope Array

The Allen Telescope Array is a telescope that is cheap and very effective for space exploration. This array uses microwaves and radio waves. The co-founder of Microsoft (Paul Allen) funded this experiment in 2001. The SETI Institute started the experiment in October of 2007.

Why is it important?

Regular large single dishes are very expensive. Then if you want to improve their performance, it is very hard and expensive to do so. The Allen Telescope on the other hand has many small dishes in a large dish. Then they make many of these into an array of telescopes. This method is very cheap and is easy to improve the telescopes. This telescope has 5 times more range than the previous project developed in 1999. This means that we will be able to explore more of the universe in a cheaper way than ever before.
