From BBC: Astronomers have found a planet whose skies are illuminated by four different suns – the first known of its type. The distant world orbits one pair of stars which have a second stellar pair revolving around them. The discovery was made by volunteers using the website along with a team from UK and US institutes; follow-up observations were made with the Keck Observatory. It is thought to be a “gas giant” slightly larger than Neptune – more than six times the radius of the Earth.
