The largest within the southern hemisphere has joined the seek for technosignatures, alerts that point out the presence of know-how developed by extraterrestrial intelligence. A brand new instrument utilized by the , which is in a distant area of South Africa, will enhance the variety of targets that Breakthrough Listen can observe by an element of 1,000.
A group of engineers and astronomers concerned with Listen, an initiative that is , spent three years engaged on the instrument, which is alleged to be probably the most highly effective tools ever deployed to help the seek for technosignatures. The instrument is built-in with MeerKAT’s management and monitoring programs.
Listen is already using the Green Bank Telescope (GBT) in West Virginia, the Parkes Telescope in Australia and others in its hunt for technosignatures. What’s completely different about MeerKAT is that there isn’t any must bodily transfer its antennas. Its 64 dishes can monitor an space of the sky 50 occasions bigger than what GBT can view without delay.
“Such a large field of view typically contains many stars that are interesting technosignature targets,” Listen principal investigator Dr. Andrew Siemion . “Our new supercomputer enables us to combine signals from the 64 dishes to get high resolution scans of these targets with excellent sensitivity, all without impacting the research of other astronomers who are using the array.”
Along with having the ability to monitor a bigger space of the sky at a given time, the power to scan 64 objects without delay will assist Listen to detect and dismiss interfering alerts from spacecraft launched by people, comparable to satellites. One of the primary targets that the brand new instrument will observe is Alpha Centauri. In 2020, Listen detected an odd radio sign coming from Proxima Centauri, the closest star to our solar and a member of the Alpha Centauri system.
“It will take us just two years to search over one million nearby stars,” Listen project scientist Dr. Cherry Ng said. “MeerKAT will provide us with the ability to detect a transmitter akin to Earth’s brightest radio beacons out to a distance of 250 light years in our routine observing mode.”
