KEPLER 10-C

Kepler-10C is an enormous and dense rocky planet. It inhabits the constellation Draco (560 light-years away). The most intriguing aspect of this planet is its weight which is 17 times greater than that of the earth, but is is also 2.3 times larger than the earth. The planet is mainly composed of heavy solids, which is quite perplexing considering its size. Kepler-10C's solar system is estimated to be 11 billion years old and what is most astonishing about this calculation is that it insinuates that dense planets that were not "gas giants" (e.g. Jupiter) were able to form after the formation of the universe. The number of planets fostered by the Kepler system seems to be around 2,700. But, what is the main factor that contrubtes to the astonishment of the discovery of this planet? Well, this information suggests that extraterrestial life may be found within a few years and that is truly an exiting prospect. 

Physics and the World Cup?

According to National Geographic, the new World Cup soccer ball, named Brazuca, is a six-panel ball that is said to move in a much more predicatble manner than previous balls. Traditional soccer balls are composed of 32 leather panels that are hand-stitched, but since 2006 soccer balls were modified in order to include balls that contained less panels and whose panels were glued and not stitched. Physicist Sungchan Hong from the University of Tsukuba, along with his colleagues, conducted an experiment in which the new ball and previous balls were sent in a specific direction in a wind tunnel. They concluded that the new brazuca ball was much more reliable in terms of movement and experienced less drag while in the air. However, the the majority of the variables in the study were controlled unlike the conditions that would affect a ball in a normal stadium.
