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.
The last project being compared to the Allen Telescope.
