Slide 142

ALMA Atacama Large Millimeter Array

Increase current sensitivity of millimeter/submillimeter telescopes by 40 times.

Sixty-four 12-meter diameter antennas

Slide 143

SKA Square Kilometer Array

To see galaxies during the earliest epochs of their formation requires at least 20 times more collecting than is provided by the largest radio telescope in operation today.

Such sensitivity would be provided by a radio telescope that has a collecting area one square kilometer.
