An international team of astronomers, who were part of the first mission to detect signs of life in the universe, have published their findings in the Astrophysical Journal.
They used a ground-based telescope in Chile to detect the signals, which were recorded by a detector located in Chile.
“We detected the first signal of life that we can see in the Universe,” said lead author of the paper, Andrea Di Girolamo, of the Institute for Advanced Study in Italy, in a statement.
“The signal is of the same nature as the one we found in 2007 in the Canary Islands.”
The team found the signal by using a technique called “spectroscopy,” which involves using radio waves to measure their frequency.
This technique is extremely sensitive and requires a very large antenna.
“In addition to the radio telescope we used, we used other instruments and instruments that have different capabilities,” said Di Gimino.
The signal detected in Chile was one of the earliest to be detected in the past four years, and was picked up by the Very Large Telescope in Chile, which was located about 3.2 billion light-years away from Earth.
“We did not detect anything in Chile,” said co-author Stefano Rizzo, the director of the Chile Observatory for Infrared Astronomy.
The signal was picked out in about one hour, and only a small portion of the radio spectrum was observed.
“The signal we detected in Chichén Itzá was a very bright signal, which means it was not caused by an astronomical phenomenon.
The faintest signal was the strongest signal that we detected, and this was due to an optical phenomenon,” said Rizza.
Di Giroama and Rizzi, along with their colleagues, are also planning to use the radio data to find other signals that could be extraterrestrial in origin.
“Our next step is to search for more signals that we don’t know about,” Rizzin said.
