In what can only be described as a fascinating reversal of roles, Canadian astronomers announced the discovery of a planet 90 light-years away which appears to heat up the star around which it orbits. This discovery is a first since, as is the case with Earth and the Sun, we know that planets are heated by their stars. This new phenomena in which the planet causes an increase in the star's surface temperature (an increase of more than 750 degrees F/400 degrees C) appears to be a result of the powerful magnetic field around the planet transferring energy to the surface of the star. You can read more details about the discovery in this article at CNN.com.

Scientists recently discovered an extrasolar planet in a triple-star system. Previously thought impossible due to competing gravitational forces, the discovery challenges current planet formation theories. Located in the triple-star system labeled HD 188753 some 149 light-years away in the constellation Cygnus, the newfound planet is a gas giant slightly larger…
