Oumuamua signals: SETI's listening
Hello All,
Enough doubt exists that the interstellar asteroid Oumuamua may *not* be a natural object that additional observations—including radio telescope observations by SETI and Breakthrough Listen, to detect any leakage radiation from it—are now being conducted (see: http://www.google.com/search?ei=Vdo...1.0.ShVFCFHnMbY ). Its natural-seeming photometric reddish color (combined with its very odd total lack of cometary outgassing despite this), its needle-like proportions (~800 meters long, yet only ~80 meters wide), its obvious strength and solidity (a “rubble pile” of those proportions would have broken apart even given Oumuamua’s relatively slow rotation), and its high-velocity entry into our solar system, have raised suspicions among some scientists that Oumuamua might possibly be an interstellar probe or a starship—perhaps a derelict one—instead of a natural object.
