Mal Ruderman (KIPAC, Stanford) . What do we see when we look at the surface of a neutron star from a great distance? ... The new point that is made is a consequence of near-relativistic electron-positron flows expected in the near-magnetosphere's of "young" (not older than about a million years) neutron stars. Because of cyclotron resonance scattering by these pair-flows on surface X-ray and UV emission, we do not see unprocessed suface emission. ...

Milky Way X-ray background emission « »: , . ... RXTE , . ... Using near-infrared Galaxy intensity measured with COBE/DIRBE experiment and X-ray data from RXTE and INTEGRAL it was shown that X-ray brightness of the Galactic background emission closely follows its stellar density and can be explained by a cumulative emission of a large number of weak Galactic X-ray sources. ... Map of Galactic background emission in hard X-ray energy band obtained with INTEGRAL observatory. ... 2006, &, 452, 169 ., ...

... The ancient chronical said about the colour rings around the Sun and the Moon, about three suns in the sky, light columns, bright lightning, different "comets" rushing to the Earth, moving among the stars or round the Earth with the sky. All these occurrences may be divided into three categories: one that occur in the near or far space, processes going on in the Earth atmosphere under the influence of cosmic factors and at last the occurrences connected with the Earth atmosphere. ...

... We present a photometric and spectroscopic study of the unique isolated nearby galaxy KKR25. The isolated dwarf spheroidal (dSph) galaxy KKR25 was discovered by Karachentseva, Karachentsev Richter (1999, A , 135, 221) during the search of dwarf galaxies in the direction of the Local Void. In spite of its isolation KKR 25 has no gas and looks like a normal dwarf spheroidal system. ... This is the first known planetary nebula in a dwarf spheroidal galaxy outside the Local Group. ...

... It?s needs solution satellite?s orientation problem for defining location of sources of ionospheric emissions above Earth?s surface with necessary accuracy. There is possibility to define orientation of photometric devices by using TV images of star background. The CCD TV camera is designed for recording of images of star sky, Earth? limb and adjoining part of Earth? surface to fix the orbit point coordinates during the measurements by FAGOT and SICH-F devices. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

. Here it seems you see only diffuse top clouds. But actually i'd like to show you the optical effect known as "Glory". It consists in formation of colored circles around the shadow of the plane . hovering under the clouds.
