An electromagnetic pulse, or EMP, bomb is a bomb that’s designed to go above the atmosphere and release huge amounts of energy. In less than a billionth of a second, the electrical intensity on Earth’s surface would become so hot that microchips would fry, power lines would overload and the electric grid would collapse.
Everything with microelectronics in it would stop: your car, your computer, the subway. There would be no electricity.
Researchers at the space agency believe they have discovered vital clues that appeared to indicate that primitive aliens could be living on the planet.
They have discovered that life forms have been breathing in the planet’s atmosphere and also feeding on its surface’s fuel.
Nicolaus Copernicus, the 16th-century astronomer whose findings were condemned by the Roman Catholic Church as heretical, was reburied by Polish priests as a hero on Saturday, nearly 500 years after he was laid to rest in an unmarked grave.
His burial in a tomb in the cathedral where he once served as a church canon and doctor indicates how far the church has come in making peace with the scientist whose revolutionary theory that the Earth revolves around the Sun helped usher in the modern scientific age.
Aliens almost certainly exist but humans should avoid making contact, Professor Stephen Hawking has warned. In a series for the Discovery Channel the renowned astrophysicist said it was "perfectly rational" to assume intelligent life exists elsewhere.
The ocean depths are home to myriad species of microbes, mostly hard to see but including spaghetti-like bacteria that form whitish mats the size of Greece on the floor of the Pacific.
The survey, part of a 10-year Census of Marine Life, turned up hosts of unknown microbes, tiny zooplankton, crustaceans, worms, burrowers and larvae, some of them looking like extras in a science fiction movie and underpinning all life in the seas.
Three species of creature, which are only a millimetre long and resemble jellyfish encased in shells, were found 2.2 miles (3.5km) underwater on the ocean floor, 124 miles (200km) off the coast of Crete, in an area with almost no oxygen.
The animals, named Loriciferans due to their protective layer, or lorica, were discovered by a team led by Roberto Danovaro from Marche Polytechnic University in Ancona, Italy.
The remarkable remains of two ancient human-like creatures (hominids) have been found in South Africa. The fossils of a female adult and a juvenile male - perhaps mother and son - are just under two million years old.
