NASA Wants to Nuke Asteroids That Threaten to Destroy Earth
Moscow (Sputnik) Jun 28, 2015
NASA has joined forces with a nuclear arms agency to learn more about how to deflect, or possibly destroy with nuclear power, asteroids or comets that may collide with Earth and obliterate the planet. Comets and asteroids are the cosmic rubble left over from the birth of the solar system. Composed primarily of dirty ice, comets are often knocked loose from their home orbits beyond Pluto bringing them closer to Earth and making them unpredictable visitors in our planet's neighborhood. Asteroids, on ... read more

Hubble sees a 'behemoth' bleeding atmosphere around a warm exoplanet Astronomers using NASA's Hubble Space Telescope have discovered an immense cloud of hydrogen dubbed "The Behemoth" bleeding from a planet orbiting a nearby star. The enormous, comet-like feature is ... more		Giant galaxy is still growing Astronomers expect that galaxies grow by swallowing smaller galaxies. But the evidence is usually not easy to see - just as the remains of the water thrown from a glass into a pond will quickly mer ... more		FAA: Atlanta fireball was a meteor, not a plane crash A bright fiery object was seen streaking across the night sky in Atlanta and throughout the Southeast in the early hours of Monday morning. ... more
				How the brightest lights in the universe 'flicker' Supermassive black holes pull in gas with great force from their surroundings. As the gas rotates around the black hole, it becomes progressively hotter through friction and begins to radiate. This ... more		Astronomers explain why a star is so hot right now Astronomers have solved a mystery over small, unusually hot blue stars, 10 times hotter than our Sun, that are found in the middle of dense star clusters. The international team found the so-called ... more

Can Planets Be Rejuvenated Around Dead Stars? For a planet, this would be like a day at the spa. After years of growing old, a massive planet could, in theory, brighten up with a radiant, youthful glow. Rejuvenated planets, as they are nickname ... more		Iron: A biological element? Think of an object made of iron: An I-beam, a car frame, a nail. Now imagine that half of the iron in that object owes its existence to bacteria living two and a half billion years ago.
