Recently, astronomers used machine learning to mine data from South Africa’s MeerKAT telescope.
About MeerKAT Telescope:
- It is situated in South Africa’s Northern Cape province and is a precursor to the Square Kilometre Array (SKA) telescope.
- It was originally known as the Karoo Array Telescope (KAT) which would consist of 20 receptors.
- At present, it is having an array of 64 interlinked receptors.
- It uses radio signals from space to study the evolution of the universe and everything it contains.
- Astronomers used a coding framework called Astronomoly and found Odd Radio Circle, which they named SAURON (a Steep and Uneven Ring Of Non-thermal Radiation).
What are Odd Radio Circles?
- These are very large mysterious objects that are highly circular and bright along the edges at radio wavelengths.
- Although ORCs are bright at radio wavelengths, they cannot be observed at visible, infrared or X-ray wavelengths.
What is Machine learning?
- It is a branch of artificial intelligence (AI) and computer science which focuses on the use of data and algorithms to imitate the way that humans learn, gradually improving its accuracy.
Q1) What are Radio signals?
Radio signals are a type of electromagnetic radiation that is used to transmit information from one location to another through the air or vacuum. They are used in various communication systems, such as radio broadcasting, television broadcasting, mobile phones, and satellite communication.
