KOMPAS.com – In 2019, researchers said that a mysterious signal was detected from Proxima Centauri, the closest star to the sun, which is only 4.2 light years away, which is thought to have come from aliens.
However, the radio signal detected by this telescope in Australia does not appear to be coming from aliens.
This was revealed by the researchers through a report published in Nature Astronomy year 2021.
“This is man-made radio interference through various technologies, possibly at the Earth’s surface,” said University of California astronomer and report author Sofia Sheikh. Nature, Monday (10/25/2021).
Initially the disturbance was detected by the Breakthrough List. This phenomenon seemed interesting enough that astronomers participated in researching and searching for its origin for almost a year.
This is the first time data from Breakthrough Listen has prompted researchers to look deeper, so they can study other signals in the future.

Since 2016, Breakthrough Listen has been using telescopes around the world to listen for possible mysterious signals from aliens or aliens.
The program has captured millions of radio blips of unknown origin, almost all of them originating from radio interference on earth such as cell phone towers or airplane radar.
However, the signal captured in 2019 was different. The signal was detected by the Parkes Murriyang radio telescope in southeastern Australia and came from the direction of Proxima Centauri.
Proxima Centauri is of great interest to SETI researchers, not only because of its proximity.
The star has at least two planets, one of which orbits at just the right distance to accommodate the water on its surface that is a condition for habitability for living things.
The mysterious signal was first discovered last year by Shane Smith, a researcher intern at Breakthrough Listen.
