Could mysterious radio signals be from ET?
A mysterious radio signal received by the Arecibo Observatory, Puerto Rico is a message from another civilization in our galaxy? Scientists at the Planetary Habitability Laboratory (PHL) say it is highly unlikely, but the particular signs of the red dwarf star Ross 128 increase in speculation, as its origin remains a mystery.
According to Abel Méndez, PHL director of the University of Puerto Rico at Arecibo, the star of the signals, which are 11 years from Earth in the constellation Virgo, were captured by the giant of Arecibo radiotôle on May 13 to At twelve-fifty-three GMT.
The small weak star was under observation in a study of red dwarf planetary systems, including Gliese 436, Ross 128, Wolf 359, HD 95735, BD 202465, V * RY Sex and K2-18.
Méndez said that only Gliese 436 and K2-18 are known to have planets, but other stars were investigated in April and May to learn more about their radiation and magnetic environments that could provide clues as to the presence of stars or dark planets .
Ross 128 has no known planets or comrades, but is already interesting to astronomers, as it is classified as an active star torch because of its tendency to suddenly increase its brightness for a few minutes.
Ross 128 was observed by the Arecibo Observatory in the C band of 4 to 5 GHz, on May 12 at 9:55 local time.
Nothing unusual was seen in time, but when data were analyzed two weeks later, unusual signals were received in the 10-minute dynamic range.
The signals are composed of non-polarized pulses with signs of being periodic with high characteristics similar to those of the dispersion. Periodicity is a signal of an intelligent signal, although many natural phenomena, such as pulsars, possess.
After eliminating radio interference from Earth, Méndez and his team reduced the signal source to three possibilities.
