Image released March 12, 2014. CREDIT: ESO/Digitized Sky Survey 2 A powerful telescope in Chile has imaged the largest yellow star ever discovered. The star, called HR 5171 A, shines 12,000 light-years from Earth in the center of a new image released today (March 12). Known as a yellow hypergiant, The star is more than 1,300 times the diameter of the sun, much larger than scientists expected after earlier observations, European Southern Observatory officials said in a statement. You can see the yellow hypergiant in a new video from ESO as well. The new measurements place the star as one of the top 10 largest stars ever discovered. Scientists using ESOs Very Large Telescope Interferometer to observe the star got another surprise as well. HR 5171 A is actually part of a double star system, with its companion orbiting extremely close to the hypergiant.
