Next: Radiopulsars as Sources of Up: Cosmic Rays and Evolution Previous: Cosmic Rays and Evolution . Presently, there is little doubt that galactic CR can be generated at rapidly expanding shock fronts produced by supernova explosions. ... Statistical properties of radiopulsars in our Galaxy indicate a formation rate of NS of about 1 per 10-20 years in the present cosmological epoch, while direct astronomical observations have so far not detected supernova explosions at this high rate. ...

... Here is a brief outline of the current theory of the events in the early history of the solar system: . A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. ... The gas cools off enough for the metal, rock and (far enough from the forming star) ice to condense out into tiny particles. (i.e. some of the gas turns back into dust). ... Once the larger of these particles get big enough to have a nontrivial gravity, their growth accelerates. ...
