The SERENDIP project to look for this uses radio data from the Arecibo L-Band Feed Array.
The object ALH84001 contained magnetite crystals which were speculated to be signs of the existence of this phenomenon. The SERENDIP project to look for this uses radio data from the Arecibo L-Band Feed Array. This phenomenon was searched for by observing tau ceti and epsilon eridani at the 21 centimeter wavelength in project Ozma. A promising signal found in the search for this was circled and the (*) word "Wow!" written next to it. The amount of this in our galaxy was estimated as the product of seven terms including birth rate of stars, the fraction of stars with planets, and the fraction of planets which are habitable. SETI looks for, and the Drake equation describes, for 10 points, what phenomenon of life outside the earth?
