Nearby 'super-Jupiter' detected, could be one of coldest exoplanets, say researchers

As planets cool and contract over their lifetime, they become significantly fainter and, therefore, harder to image, they said. The US space agency has confirmed the existence of about 5,000 of the billion exoplanets in our galaxy. Orbiting the star Epsilon Indi A, Epsilon Indi Ab has been dubbed a "super-Jupiter".
