Galileo Finds Giant Iron Core in Jupiter's Moon Io . Jupiter's volcano-pocked moon Io has been found by NASA's Galileo spacecraft to have a giant iron core that takes up half its diameter, scientists report in today's issue of Science magazine. The spacecraft also has detected a large "hole" in Jupiter's magnetic field near Io, leading to speculation about whether Io possesses its own magnetic field. If so, it would be the first planetary moon known to have one. ... Space History Galileo . ...

... The picture shows a 2-dimensional sketch of the outflowing wind of a quasar (Elvis 2000, Astrophysical Journal , vol.545, p.63-76). In the funnel-shaped disk wind Elvis (2000) model a wind arises from a restricted range of radii on the accretion disk around the central black hole. Initially the wind makes a large angle to the disk plane (and so is roughly cylindrical). ... Looking through the quasi-cylindrical part of the wind we see UV and X-ray warm absorbers. ...

Damage to the gate structure oxide layers from keV level X-rays will likely result in increased dark current and decreased full-well capacity. ... Figure 14 shows the increase in dark current versus incident electron energies. ... The back-thinned CCD's 'lifetime' is defined, herein, to be a 50 electron per pixel increase in CCD dark current per 16.7 millisecond integration period. ...

The efficiency of interaction of radiation with a particle and hence its optical properties depend on the particle chemical composition, size, shape, structure, etc. ... Particle size expressed in units of the wavelength of incident radiation, together with chemical composition, most strongly affects the optical properties of a scatterer. ... There are many methods to solve the light-scattering problem for a homogeneous spheroid (our survey of the light-scattering methods see here ). ...

A Jet from the Sun . ... Credit Copyright: Hinode , JAXA , NASA Explanation: What powers the solar wind? ... The cause of the solar wind has been debated for decades but is thought to be rooted in Alfvхn waves generated by the ever changing magnetic field of the Sun. ... The jets and waves are themselves ultimately created by magnetic reconnection events, rapid events where lines of constant magnetic field suddenly move extremely rapidly, dragging electrons and proton s along with them. ...
