Dust from beyond the solar system
Article Abstract:
Meteoroids are produced by interstellar dust particles continually hitting the earth. A meteoroid loses mass and velocity rapidly and leaves a train of ionized gas. The train could reflect radar pulses. Meteor scientists have often wondered whether there were any hyperbolic orbits among incident meteoroids. It has been detected that the earth's solar system is a source of hyperbolic meteroids for other planetary systems.

Ancient cosmic spherules
Article Abstract:
The discovery of cosmic spherules in sandstone over 1.4 billion years old from Finland has been reported by Deutsch, Greshake, Pesonen and Pihlaja. Cosmic spherules are an abundant form of extraterrestrial material and were first described in 1876. The new discovery provides a new way of tracking long term changes in atmospheric oxygen content, along with changes in the meteroroid population of the Solar System.

Shaken on impact
Article Abstract:
Thomas and Robinson to examine the impact of asteroid Eros that led to the formation of craters discovery conducted a study. The findings had implications on how one view the structure of asteroids from surface observations like craters and other landforms and their degradations could be used as proxies for seismic data thereby addressing any hazards if present.
