Want faster data and a cleaner planet? Start mining asteroids

Mining asteroids might seem like the stuff of science fiction, but there are companies and a few governments already working hard to make it real. This should not be surprising: compared with the breathtaking bridges that engineers build on Earth, asteroid-mining is a simple, small-scale operation requiring only modest technological advances. If anything is lacking, it is the imagination to see how plausible it has become. I am afraid only that it might not arrive soon enough to address the urgent resource challenges that the world is facing right now.

Earth 2.0: Kepler-452b

NASA’s space observatory Kepler may have discovered a possibly Earth-like planet, a rocky world orbiting a Sun-like star at almost the exact same distance Earth orbits our own Sun: Kepler-452b!

“The new Earth” is located 1,400 light-years from us. It orbits a Sun-like star that is 4% more massive and 10% brighter than our Sun. Kepler-452b is 1.6 times the size of Earth and the scientists are fairly sure that it is a rocky world.

Great white shark fight caught on camera (video)

The Great White Sharks, kings of the seas. They are fearless hunters. And they are big: a mature individual can grow up to 6.4 m (21 ft) in length (there are even reports of great white sharks measuring over 8 m (26 ft), and 3,324 kg (7,328 lb) in weight). According to Wikipedia, “The great white shark has no natural predators other than the Orca.” But this is not always true. Sometimes, great whites attacks and even hunt each other.

Even though the great whites are known to generally avoid conflicts with each other, the phenomenon of cannibalism is not alien to this species. This rare phenomenon, has been caught on camera recently: London-born diver Adam Malski (33) filmed a fight between two great white sharks 50 kilometers off the coast of South Australia’s Neptune Islands.
