The southern hemisphere's largest radio telescope has joined the hunt for technosignatures, or signals indicating the presence of technologies created by extraterrestrial intelligence. Breakthrough Listen will be able to observe 1,000 more targets thanks to a new instrument used by the MeerKAT radio telescope in a secluded region of South Africa.
Listen, an initiative that seeks signs of intelligent extraterrestrial life spent three years developing the instrument, which is said to be the most powerful device ever deployed to aid in the search for technosignatures. MeerKAT's control and monitoring systems are integrated with the instrument.
MeerKAT's 64 dishes can supervise a 50 times larger area of the sky than GBT can. It is already searching for technosignatures using the Green Bank Telescope (GBT) in West Virginia, the Parkes Telescope in Australia, and other telescopes. Its 64 dishes do not require physically moving their antennas from one location to another.
"A large field of view like this usually contains a lot of stars that are exciting technosignature targets." "Dr. Andrew Siemion, principal investigator, said in a statement. "Our new supercomputer allows us to merge signals from the 64 dishes in order to obtain high resolution scan results of these targets with high sensitivity, all while not interfering with the research of other astronomers who use the array."
MeerKAT, a new European Space Agency instrument, will be able to track 64 objects at once in a larger area of the sky. This will allow scientists to identify and reject interfering signals from human-launched spacecraft, such as satellites. Alpha Centauri, the nearest star to our sun, will be one of the first targets observed by the new instrument.
