"Cooler Than a Campfire: Discover the Stellar S'mores Star"

Researchers have discovered the coldest star ever detected with a radio telescope, a brown dwarf smaller than Jupiter with a temperature of 797 degrees Fahrenheit. Brown dwarfs, also known as "failed stars," are too small to undergo nuclear fusion like larger stars. The discovery was made using data from the Australian SKA Pathfinder Telescope and confirmed with other radio telescopes. The findings provide insights into the magnetic field properties of brown dwarfs and contribute to a better understanding of the 3-D structure of these celestial bodies.
