NASA’s Kepler mission has confirmed the discovery of a planet in the habitable zone of a sun-like star. A NASA researcher says the Earth-like planet would have a surface temperature around 70 degrees Fahrenheit. This makes it a so-called "Goldilocks planet" — not too hot, not too cold, just right to support life. Researchers have also measured the largest black holes yet. A team of UC Berkeley scientists have confirmed the discovery of the two biggest black holes yet to be documented. Each black hole is 10 billion times larger than our sun.
