Lee Rannals for redOrbit.com - Your Universe Online Dr Christopher Russell presented a paper at the European Planetary Science Congress on Tuesday, explaining why one asteroid has lost its magnetic mojo. Asteroid 2201 Oljato orbits the Sun every 3.2 years, and during its lifetime, NASA's Pioneer Venus Orbiter has observed three passages of the space rock between Venus and the Sun. Each time the asteroid has been observed, Oljato had a marked increase in the region of unusual magnetic...

Despite the great differences between the atmospheres of Venus and Earth, scientists have discovered that very similar mechanisms produce lightning on the two planets. The rates of discharge, the intensity and the spatial distribution of lightning are comparable, thus scientists hope to be able to better understand the chemistry, dynamics and evolution of the atmospheres of the two planets. These results were presented by Dr. Christopher Russell at the European Planetary Science Congress, on...

There are hundreds of thousands of asteroids circling our sun, all so-called "minor planets" left over from the formation of the solar system. Much about them remains mysterious. Solving these mysteries could shed light on the past, present and future of cosmic impacts on Earth. Among the puzzles: Missing asteroids There should be far more asteroids that resemble Vesta, the second largest body in the asteroid belt. The outermost layers of Vesta are composed mostly of basaltic rock—the...

Their infiltration began - like so many other infiltrations - with a tell-tale contrail of smoke and flame creating a supersonic slash across the afternoon sky. But this time they would not go unnoticed. This time, two Australian station workers, just going about their job, opening a gate to a boundary fence, witnessed their arrival. The eyewitnesses later said they observed a "fireball with sparks coming off," streaking from the south to the north, make its descent into a hummock of spinifex...
