Press release: Eurekalert: Team hopes to use new technology to search for ETs

Quote:

Richard Conn Henry, a professor in the Henry A. Rowland Department of Physics and Astronomy at Johns Hopkins' Zanvyl Krieger School of Arts and Sciences, is joining forces with Seth Shostak of the SETI Institute and Steven Kilston of the Henry Foundation Inc., a Silver Spring, Md., think tank, to search a swath of the sky known as the ecliptic plane. They propose to use new Allen Telescope Array, operated as a partnership between the SETI Institute in Mountain View, Calif., and the Radio Astronomy Laboratory at the University of California, Berkeley.
[...]
According to the researchers, the critical place to look is in the ecliptic, a great circle around the sky that represents the plane of Earth's orbit. The sun, as viewed from Earth, appears annually to pass along this circle. Any civilization that lies within a fraction of a degree of the ecliptic could annually detect Earth passing in front of the sun. This ecliptic band comprises only about 3 percent of the sky.

Three sun-like stars which lie in the plane of the ecliptic are 18 Scorpii, 37 Geminorum and 55 Cancri. Note that interstellar messages have already been sent to 37 Gem and 55 Crc, also, by accident, a number of asteroid scanning radar beams have been sent in their general direction. So if there are any civilisations around those stars, they may notice a signal or two arriving in due course.

For some reason 18 Sco has not been targeted as far as I can tell.

Edit; none of those three stars lie within a fraction of a degree of the ecliptic, however.

At least we'll know who to blame when the Klingons or the Goauld come calling...

Turtleheads can be fun. Snakeheads are not.
