Will ‘space junk’ problem intensify?
Moscow (Voice of Russia) Aug 21, 2013 – The United States is planning to shut down a key component of its space surveillance network that tracks satellites and “space junk” orbiting the Earth. As a result, satellite launches and flights to the International Space Station (ISS) may involve a higher degree of risk. The Air Force Space Surveillance System known as Space Fence consists of three two-mile-long transmitter antennae and … more
Earliest known iron artifacts come from outer space
London, UK (SPX) Aug 21, 2013 – Researchers have shown that ancient Egyptian iron beads held at the UCL Petrie Museum were hammered from pieces of meteorites, rather than iron ore. The objects, which trace their origins to outer space, also predate the emergence of iron smelting by two millennia. Carefully hammered into thin sheets before being rolled into tubes, the nine beads – which are over 5000 years-old – were orig … more
New map reveals Earth’s gravity not the same around the globe
Perth, Australia (UPI) Aug 20, 2013 – Australian scientists say satellite and topographic data has provided the most accurate map of the variations in Earth’s gravity at locations around the world. The new high-resolution map shows fluctuations in gravity at different locations on Earth’s surface are greater than thought, researchers at Curtin University in Perth in Western Australia reported. Gravity is often assume … more
Study: Planets might be ‘born free’ without a parent star
Stockholm, Sweden (UPI) Aug 20, 2013 – Swedish astronomers say they’ve discovered tiny, round, cold clouds in space that have the right characteristics to form planets without a parent star. Previous research suggested there may be as many as 200 billion free-floating planets in the Milky Way galaxy, with most astronomers assuming such “rogue planets,” which don’t orbit a star, must have been ejected from existing planetary … more
