Astronomy: Consider the data received from spacecraft on a mission (such as
Voyager or Galileo) and all the data received from radio telescopes, which are
specialized antennas used to receive radio waves from astronomical bodies.
A common example is the Search for Extraterrestrial Intelligence (SETI) project
(
http://www.seti.org/
), which looks for extraterrestrial signals by observ-
ing radio frequencies arriving from space. The amount of data received and
the computer power used to analyze a portion of the sky for a single hour
is impressive (

). If
aliens are out there, it’s very hard to spot them. (The movie Contact
https://

explores what could happen should humans actually intercept a signal.)
