Ask the Astronomers Live: A Planet in a Galaxy Far Far Away

A planet may have been detected in a galaxy outside of our own. There are thousands of planets detected around stars in our own Milky Way galaxy, but for the first time we may have detected a planet in another galaxy, called the Whirlpool Galaxy, which is more than 23 MILLION lightyears away. Not only is this planet unusual for being discovered in a galaxy far, far away, but it is also usual because it orbits a binary star system which produces an enormous amount of X-rays. It was by monitoring those X-rays that helped identify the planet. Tune in to see how all this was accomplished on this episode of Ask the Astronomers Live!
