Space is incredible...

The planet, known as TrES-4, is mainly composed of hydrogen and around 75 percent larger than Jupiter – the largest planet in the Earth's solar system. TrES-4's fiery temperature of 2,300 degrees Fahrenheit makes it unlikely anything lives on the planet.

TrES-4 completes a full revolution around its star in less than four days, meaning a standard week on Earth is the equivalent of almost two years on TrES-4.

The planet is so light astronomers believe it would be able to float on water. The planet's density is about 0.2 grams per cubic centimeter – just a bit more than a wine cork, but less than balsa wood.

I came across this recently. I think it's amusing that finding extrasolar planets sends some people into a frenzy... still, I'm curious to see what they discover next. It is always entertaining to read about these new discoveries.
