In December of 2011, Nasa confirmed the discovery of the first planet found in the habitable zone of a “sun-like” star. They named the planet Kepler-22b. The planet is about 2.5 times the radius of Earth, and orbits comfortably within the habitable zone. Scientist are unsure of the composition of the planet, but the discovery has proven to be a huge step in finding a “twin Earth.”
Dark Flow, discovered in 2008, is more of a mystery than an answer. Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can’t be explained by any of the known gravitational forces in the observable universe. Astronomers are calling the phenomenon “dark flow.” By observing large galaxy clusters, scientist have found over 700 galaxy clusters moving at a peculiar velocity toward a distant part of the Universe. Some scientist have even gone as far as saying Dark Flow may be caused by another Universe pressing against our own. There are, however other scientist who have criticized the Dark Flow discovery.
Nasa’s two Voyager probes have found magnetic bubbles in the region of the solar system known as the Heliosheath, 9 billion miles away from Earth. In the 1950s, scientist believed this region of space was relatively smooth. But when Voyager 1 entered the Heliosheath in 2007, and Voyager 2 got there in 2008 they detected a turbulence that is generated by the Sun’s magnetic field, that creates magnetic bubbles up to 100 million miles wide.
