... October 25, 1995 . Painting with Solar Neutrons . Credit: NASA , CGRO , COMPTEL collaboration. Explanation: Solar flares are propelled high above the Sun's surface by powerful, twisted magnetic fields. The flares spew high energy atomic and subatomic particles into space. During an intense solar flare on June 15, 1991, a spray of solar neutrons was detected by the COMPTEL instrument onboard NASA's Compton Gamma Ray Observatory. ... About APOD | ...

Most current theories for magnetospheric emission can be grouped into polar cap, outer gap, and nebular models. These models, at least in some cases, need not be mutually exclusive; the Crab pulsar (among others), for example, shows clear evidence for pulsed emission from the magnetosphere and unpulsed emission from the surrounding nebula. ... This suggestion is strengthened by observation of a distinct soft emission component, consistent with the cooling scenario, from several of these pulsars. ...

The classic solution for homogeneous sphere was suggested in 1899 by A.E.N. Love [ 330 ], in 1908 by G. Mie [ 342 ] and in 1909 by P. Debye [ 199 ]. ... Traditionally the theory of light scattering by a sphere is called the Mie theory. ... The exact solutions of the Mie problem for an optically active sphere (i.e. a sphere of optically active material [ 7 ]) and for a sphere with an optically active mantle were first obtained in 1974-5 by S. Bohren [ 158 , 159 ]. ...

Next: Field of View Up: CCD Scientific Performance Previous: Back Illumination . The CCD acts as a storage medium, and with frame times of the order seconds, there is no obvious method of employing prompt co-incidence rejection of charged particle events. ... In conventional CCDs, a m track length results in an equivalent energy deposition of 5 - 6 keV, and significant confusion with X-ray events arises. ... A trade-off between rejection efficiency and spectroscopic efficiency is required. ...

After fragments of the Vortex sleeves separated, whirlwinds of second and third orders ("NC" - new micro-vortex) were generated- future planet cores and their satellites - all of them developing independently, governed by the common laws of development of cosmogenic vortexes. ... Our planet's core today is comprised of considerably deteriorated cosmogenic vortex; consequently, the Earth has a moderated magnetic field. ...

Next: Background Definition Up: Echelle Spectra Previous: Order Definition . ... Their removal is a rather delicate step, because in high-contrast images (such as well-exposed echelle spectra) there is always a danger of damaging the scientific contents of the frame. Particle hits can be removed from scientific exposures by splitting the exposure and comparing spectra of the same target obtained under the same instrumental configuration. ... Note that the background has been subtracted already. ...

The radiation belts around the planets are the interrnal regions of planets' magnetospheres where the own magnetic field of a planet keeps the charged particles (protons and electrons) having the great kinetic energy. ... They usually distinguish the Earth's internal and external radiation belts. the internal radiation belt of the Earth has the maximum particles density (mainly protones) over the equator in the height of 22 thousand km. ... Jupiter and Saturn have the powerful radiation belts. ...
