Asteroid whizzes safely past Earth
Boston (AFP) Feb 15, 2013 – A closely tracked asteroid, about 150-feet (45-meters) wide, whizzed safely past Earth on Friday, the same day a much smaller, previously undetected meteor hit Russia, injuring nearly 1,000 people. Live images from a telescope at the Gingin Observatory in western Australia showed the asteroid looking like a white streak, moving across against a backdrop of black sky. Astronomers said the … more

MOND used to predict key property in Andromeda’s satellites
Cleveland OH (SPX) Feb 15, 2013 – Using modified laws of gravity, researchers from Case Western Reserve University and Weizmann Institute of Science closely predicted a key property measured in faint dwarf galaxies that are satellites of the nearby giant spiral galaxy Andromeda. The predicted property in this study is the velocity dispersion, which is the average velocity of objects within a galaxy relative to each other. … more

Bern Simulation Helps Understand Origin Of Solar System
Bern, Germany (SPX) Feb 18, 2013 – Simulations boost the significance of image and measurement data from space missions: based on the example of an asteroid, Bernese astrophysicist Martin Jutzi shows how collisions with other celestial bodies can be reconstructed and that even the internal structure of so-called protoplanets can be described. These models help to understand the development of our solar system. The study appears a … more

Stay away from meteorites, government tells Russians
Moscow (AFP) Feb 15, 2013 – Russia’s authorities on Friday cautioned residents of the Urals to stay away from any unidentified objects after a meteor dramatically burned up above the region, with a precious meteorite apparently plunging into a local lake. “Russia’s emergency ministry warns all residents of the Urals… not to approach unknown objects,” the ministry said on its website, listing several numbers for peopl … more

Clues to the mysterious origin of cosmic rays
Munich, Germany (SPX) Feb 15, 2013 – In the year 1006 a new star was seen in the southern skies and widely recorded around the world. It was many times brighter than the planet Venus and may even have rivaled the brightness of the Moon. It was so bright at maximum that it cast shadows and it was visible during the day. More recently astronomers have identified the site of this supernova and named it SN 1006. They have a … more

Accelerated protons confirm origin of cosmic rays
Washington DC (SPX) Feb 18, 2013 – We are constantly being bombarded by speedy, energetic, and yet unassuming, particles called cosmic rays. These charged particles (mostly protons), continuously assail the Earth from outer space. There is general consensus among scientists that supernova remnants (the leftovers of a supernova explosion) are the sources of cosmic rays, but the final proof has been elusive since cosmic rays … more
