Today, on the 15th of November 2017, an international team of astronomers published a paper detailing the discovery of an exoplanet orbiting Ross 128. The paper was published in the journal “Astronomy and Astrophysics”. This exoplanet is labelled as one of the most plausible locations to search for alien life outside our solar system, but we maybe already found proof of alien life on this exoplanet.
Earlier this year Abel Mendez, the Director of the Planetary Habitability Laboratory, posted a short article on his blog about the bizarre radio signal coming from Ross 128. The signal was picked up by the 1,000-foot-wide Arecibo radio telescope in Puerto Rico. “The signals consisted of broadband quasi-periodic non-polarized pulses with very strong dispersion-like features.”
Mister Mendez presented 3 possible explanations for the signal:
– they could be emissions from Ross 128 similar to Type II solar flares
– emissions from another object in the field of view of Ross 128
– burst from a high orbit satellite
Back then, nobody was certain whether there was an exoplanet orbitting Ross 128. After a follow up analysis Mr. Mendez made a statement that the signal was probably caused by a geostationary satellite, HOWEVER this could not explain the strong dispersion like features of the signal. Dispersion occurs when radiosignals travel over very long distances, certain wavelenghts arrive a bit earlier than others.
Could it be that we found the true origin of the signal today with the discovery of Ross 128b?
