A world staff of astronomers has performed a double-telescopic examine of the zone the place the Wow! sign originated and didn’t detect any sign. Of their paper printed in Analysis Notes of the American Astronomical Society, the group describes their examine and what they discovered from it.
On August 15, 1977, the Massive Ear radio telescope on the campus of Ohio State College recorded a 72-second narrowband sign onto a paper tape. A number of days later, Jerry Ehman, an astronomer on the college, studied the tape and located the sign so uncommon that he scrawled the phrase Wow! subsequent to the data points.
Since that point, the sign has been mentioned at nice size within the astronomy group, however no one has been capable of clarify its origin. And till now, nobody has taken an in depth survey of the a part of the sky the place the sign originated. On this new effort, the researchers selected to rectify that state of affairs by conducting a dual-telescopic examine of the a part of the evening sky that’s believed to be the supply of the sign.
The researchers started by noting work executed by Alberto Caballero who, this previous Might, had performed an exhaustive search of the European Area Company’s, Gaia database, which accommodates information on greater than 1 billion stars. He used the database to slim down the attainable star methods which may have been concerned within the emission of the Wow! sign. In so doing, he narrowed down the chances to a single star, one known as 2MASS 19281982-2640123.
The researchers targeted their efforts on that star system utilizing two telescopes, the Inexperienced Financial institution Telescope and the Allen Telescope Array. Each had been pointed on the star system on the identical day. The Inexperienced Financial institution studied the star for 2 half-hour intervals, whereas the Allen array performed six observations that had been every 5 minutes lengthy. There was additionally one interval when the observations overlapped.
The researchers discovered no signal of a sign, a lot much less one worthy of a “Wow!” However they famous that their effort confirmed that their method is possible and might be used to check different mysterious alerts.
