Huge Yellow Star Found With Another Star On Its Surface
The largest yellow star ever discovered, 1300 times the diameter of our sun, has another star orbiting so closely they're actually touching.By Steven Sparkman | March 12, 2014
There are somewhere around 300 billion stars in our galaxy, so if the discovery of a single star is enough to make headlines, you better believe it's an impressive one.
Scientists at the European Southern Observatory, or ESO, say a yellow hypergiant in the constellation Centaurus is the largest yellow star ever discovered, and an easy contender for the top 10 largest stars of any kind. This is an actual photograph of it. (Via ESO / Digitized Sky Survey 2)
Yellow hypergiants are one of the rarest kinds of star, with only around a dozen ever discovered. That's because they're thought to be undergoing a radical change from red to blue, and the process doesn't take very long. (Via ESO / Nick Risinger / Digitized Sky Survey 2)
