6. The Black Hole Planet

6. The Black Hole Planet

TrES-2b is a lot like Jupiter: they are both nearly the same size, and it orbits a star that is similar to the sun – except, it is some 750 light years away. This Jupiter-class gas giant reflects less than 1 percent of the light which strikes. In other words, it absorbs huge amount of light, so much so that it is considered the darkest planet. It is darker that black acrylic paint or even coal. It is speculated that the atmosphere of the planet has chemicals, or mix of compounds. Interestingly, at 1800°F, it turns hot enough to emit a dull, reddish glow, which is visible probably because of all the absorbed light.
