"Sydney Astronomers Discover Surprising Radio Signals from Coldest Star"
Astronomers at the University of Sydney have discovered the coldest star yet that emits radio waves. The star, known as an ultracool brown dwarf, has a surface temperature of about 425 degrees Celsius, making it cooler than a typical campfire. While not the coldest star ever found, it is the coolest to be analyzed using radio astronomy. The star's low temperature and production of radio waves provide valuable insights into the evolution of stars and the generation of magnetic fields. The discovery was made using data from telescopes in Australia and South Africa.
