NASA has on its website a section called "Astronomy Picture of the Day" in which he published a picture of our fascinating universe, along with a brief explanation of a professional astronomer daily.
On February 6 the photo published was this:

Nobody knows for sure what caused this signal. There is a slight possibility that it could be caused by an extraterrestrial civilization. Bright colors of blue background indicate that an anomalous signal was received here on Earth by a radio telescope project search for extraterrestrial intelligence (SETI). The search for these signals is being conducted by several groups including volunteer members of the SETI League. The vertical axis represents time and the horizontal frequency. Although this strong signal has not been identified, astronomers found themselves in it many attributes that point to a much more mundane origin and ... Earth. In this case, the most likely explanation is that the signal originated by the unusual modulation between a GPS satellite and terrestrial signal unidentified. Many unusual signals detected in space remain inidentificadas. But none has been strong enough, or lasted long enough to be considered unequivocally as alien
Elsewhere, as the world with my eyes, it has also dealt with this news, but making a partial translation of the explanation of the astronomer. Guess which part?
