Astronomers using NASA's Hubble Space Telescope have discovered that the universe is expanding 5 percent to 9 percent faster than expected.
Travel to the past is probably impossible. But the future is a different story.
A distant 'super-Earth' size planet known as Kepler-62f could be habitable, a team of astronomers reports. The planet, which is about 1,200 light-years from Earth in the direction of the constellation Lyra, is approximately 40 percent larger than Earth.
