Some researchers are sceptical, saying it isn’t clear the comets would release enough hydrogen to generate something like the Wow! signal. James Bauer of the Jet Propulsion Laboratory in Pasadena, California, agrees that the hydrogen from comets can extend quite far, but still thinks the signal won’t be strong enough. “If comets were radio-bright at 21 centimetres, I would be puzzled as to why they aren’t observed more often at those wavelengths,” he says.
