Universe Today – A new visualization of data from a nuclear weapons warning network, to be unveiled by B612 Foundation CEO Ed Lu during the evening event at Seattle’s Museum of Flight, shows that ”the only thing preventing a catastrophe from a ‘city-killer’ sized asteroid is blind luck.”

Universe Today – Could life thrive in the devastated rock left behind after a meteorite impact? A new study hints that possibly, that could be the case. Researchers discovered what they think are geological records of biological activity inside of Nördlinger Ries, a crater in Germany that is about 15 miles (24 kilometers) wide.

Meridiani Journal – Big discovery: first Earth-sized exoplanet in the habitable zone of another star

Nextbigfuture – Using NASA’s Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the “habitable zone” — the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun.

While planets have previously been found in the habitable zone, they are all at least 40 percent larger in size than Earth and understanding their makeup is challenging. Kepler-186f is more reminiscent of Earth.
