No point-like features significantly exceeding the noise were found inside the full width at half maximum of the OSU fields of view, although one 26σ point-like feature was detected during one 10 second integration about 1/3° away. This allows identification of the DOA of a very brief repetition, with strong discrimination from radio interference, and eliminates the usual constraint that the signal must persist for long periods of time (around one hour) before the true DOA can be verified (because interfering signals from the horizon sometimes masquerade as coming from the look direction). We used interferometric imaging with an angular resolution of approximately 0☀7 and automated feature-finding to search for point-like features mimicking a Wow repetition, obtaining single-channel sensitivity of ∼1.2 Jy for one minute averages.

Wow signal crack#
Approximately 100 hours of data were accumulated, considerably more time than any previous follow-up campaigns. Lets crack this alien signalThe Wow signal was a strong narrowband radio signal detected by Jerry R. While previous follow-up searches have reported null results, our observations covered a 5 deg 2 field of view that extends well beyond the locus of all consistent directions of arrival (DOAs) of the original signal, and covered a 10 MHz bandwidth four times wider than the widest prior follow-up observations, using 12.8 kHz channels approximating OSU's 10 kHz resolution. Paris responded that he plans to review them and respond as soon as he's done with a current round of traveling.The Allen Telescope Array was used to search for signals with characteristics similar to the "Wow" signal, the best candidate for an extraterrestrial radio signal found during Ohio State University's (OSU's) seven-year 21 cm 10-kHz channel sky survey for signals possibly due to extraterrestrial intelligence. Oxford physics professor Chris Lintott was so put off by the comet hypothesis that he compiled a list of questions for Paris about his work. "Dixon (says) the comets were nowhere near the telescope's sight lines when the signal was found." Shostak cites the comments of Robert Dixon, who was director of the Ohio State observatory back in 1977. "The comet hypothesis, in my opinion, doesn't work," Seth Shostak of the SETI Institute concurred in a blog post. "This paper was also just really, really, really short on details that a radio astronomer would want, to the point where it likely wouldn't have passed a referee at a 'regular' journal," she writes, before going on to suggest the signal Paris picked up may have actually come from our sun rather than comets. What if fast radio bursts were powering alien starships?Ĭendes raises a tentative eyebrow at Paris' credentials and the obscure journal that published his paper, the Journal of the Washington Academy of Sciences, before moving on to the study itself.
