Violent Spacequakes Shake Earth's Magnetic Field
Spacequakes aren't the only unearthly temblors around. Scientists have also discovered starquakes (violent trembling inside stars), moonquakes and asteroid quakes (seismic tremors on the surface of the moon and asteroids, respectively). In fact, Earth can actually stimulate asteroidquakes when wayward space rocks fly too close to our planet.
all of this energy all around us, and we still burn coal and oil for it... if only we could harness all (or even some) of that energy!
probably entirely oversimplistic, but what about a huge metal rod, shouldn't a giant magnetic field like that induce an electrical charge?
That seems to me, to matter of factly state that they observed the collision, ie they were actual witnesses...no? How else can we interpret "we have directly observed a collision between asteroids for the first time.."?"We have directly observed a collision between asteroids for the first time, instead of having to infer that they happened from million-year-old remains," researcher Colin Snodgrass, a planetary scientist at the Max Planck Institute for Solar System Research in Katlenburg-Lindau, Germany, told SPACE.com.
Oh, the collision was "observed" via computer models, now I understand.The two asteroids whose remains make up P/2010 A2 were unknown before the impact because they were too faint to be detected. Scientists did not witness the collision itself because it happened when the asteroids were in the same direction as the sun, but computer models suggest the collision took place around February 2009.
