An artist’s rendition of planet CFBDSIR2149. The planet’s faint
glow looks blue through an infrared telescope. In visible
light the cold planet would actually appear red.
It’s cold and young and massive. And they call it the wanderer.
Astronomers recently discovered a new planet, named CFBDSIR2149, that is relatively close to our solar system. It is also the first convincing evidence of an accepted but yet unsubstantiated theory of roaming planets.
