... For SIMS (Secondary Ion Mass Spectrometry) analysis, a solid surface is bombarded by primary ions of some keV energy. ... The subsequent mass analysis of the emitted ions provides detailed information on the elemental and molecular composition of the surface. ... Extremely short ion pulses with a duration below . ... By rastering a fine-focussed ion beam over the surface, like an electron beam in an electron microprobe, mass resolved secondary ion images (chemical maps) can be obtained...

Astronotes Armagh Planetarium's Stellar Blog! ... Earth Satellites . ... According to Velikovsky, about 4000 years ago a giant volcano on Jupiter erupted and spewed a vast glob of debris into space, leaving the Great Red Spot behind as a permanent scar. The red hot lump ejected from Jupiter (referred to as a comet by Velikovsky) wandered into the inner Solar System, repeatedly crossing the Earth?s orbit and in fact often passing close to our helpless planet in the following millennia. ...

The foundation of my research program is in astrophysics, where almost all of our knowledge of the universe beyond our solar system derives from detecting light that has been emitted, absorbed, or scattered by atoms. Fascinating phenomena occur over times often too fast for us to recognize without instruments and an understanding of the fundamental physics. ... Software for physics and astronomy . ...

How Precise is the Orbit of (99942) Apophis and how Probable is its Collision with the Earth in 2036? ... At present the orbit of asteroid (99942) Apophis and the forces acting on it are not known with sufficient accuracy to predict with certainty its motion after the close approach to the Earth in April of 2029. As a result of this approach the current heliocentric orbit of the asteroid will be changed by Earth's gravity. ...

How the rings were formed. ... Because of the velocity of mutual collisions increases at the approaching to the planet, there is a region near an every planet where the particles reaching the definite sizes begin to pull due to the mutual collisions. ... Any big particle passes the whole cycle from the destruction to the restoration. ... Why the rings are so flat? ... The gravitation compresses the system from all sides and the rotation axis, but it cannot prevent compression along the axis. ...

... Electric field is a potential heat source for ionospheric particles (Rees, 1989). It is due to the fact that, under the action of an electric field, charged particles drift relative to one another and relative to neutral particles. ... This is called frictional heating. ... However, the effect of frictional/Joule heating of neutrals in the auroral electrojet region can lead to upward neutral wind in a region of high electron densities and strong electric fields (Winser et. al., ...
