The SETI project has been bugging the Milky Way galaxy for about 46 years now, and still has no results to show for all of its efforts. It’s all for a good cause though … they’re hoping to find radio signals from extraterrestrials and are eavesdropping on them via radio telescopes. While SETI has made no progress towards their stated goal, they are advancing in other areas.
The Carl Sagan Center has just been established and will focus on exo-biology and the search for those elusive signals. Also, the Allen Telescope Array, mostly funded by Paul Allen should improve the project bandwidth considerably. The ATA will eventually consist of 350 6-meter dishes and scan 4×10^10 stars in our galaxy for other-worldly transmissions.
The SETI premise is that the famous Drake Equation, which attempts to estimate..er guess, the number of detectable advanced civilizations in the galaxy, results in a reasonable number of civs out there. We’re thinking that that inconvenient inverse-square law of physics will result in no confirmed extraterrestrial signal ever being received.
