Wow! Signal shown as 6EQUJ5
Scientists from the Center for Planetary Science report that they managed to solve the mystery of Wow! Signal, captured in 1977. They believe it was a comet whose existence was simply unknown at the time.
In August 1977, a group of astronomers studying radio programs at the Ohio Observatory noticed an unusual 72-second signal. He was so strong that Jerry Eman couldn't resist and wrote Wow! (Wow!). Since then, scientists have started looking for the source. The assumptions include asteroids, exoplanets, and land interferences. Some even thought it was foreign news. The signal reached the frequency of 1420 MHz, which is hydrogen.
Last year, the first clues appeared when astronomers suggested the cause might be a hydrogen cloud that followed the comet. Especially since her movement perfectly explained why the signal was no longer visible. They decided that there were two comets present in the study area at this point: P / 2008 Y2 and 266 / P Christensen, which were not visible and uncovered at the time. This theory has been tested since November 2016. Until February 2017, when objects reappeared in the sky.
It turned out that the signal from 40 years ago corresponded to position 266 / P Christensen. Of course, they also checked three other comets and found similar results. Therefore, it is still difficult to identify a specific object, but they are sure that the source was one of the comets.
