. Located in the focal plane of the telescope, PlanckтАЩs Low Frequency Instrument (LFI), and the High Frequency Instrument (HFI), are equipped with a total of 74 detectors covering nine frequency channels. These detectors must be cooled to temperatures around or below 20 Kelvin so that their heat does not swamp the faint microwave signals they are designed to detect. Credit: ESA/AOES Medialab)

... Astronomy news . ... Saturnian Moon Shows Evidence Of Ammonia . Data collected during two close flybys of Saturn's moon Enceladus by NASA's Cassini spacecraft add more fuel to the fire about the Saturnian ice world containing sub-surface liquid water. ... In space, the presence of ammonia provides strong evidence for the existence of at least some liquid water. How could ammonia equate to liquid water inside an ice-covered moon in one of the chillier neighborhoods of our solar system? ...

. Space vehicle "Mariner-4". “Mariner” (English "Mariner" - a sailor) is an american autometic interplanet series for Venus, Mers, Mercury and Space investigations. They are designed for the planets flight and bringing in to the planetocentrial orbits. The maximum starting mass of "Mariner" is about 1 tone. In 1962 - 1973 10 "Mariners were launched. The surveys made by "Mariner-4" showed that Mars is also covered with the craters. The mass of the planet and its atmosphere was calculated. Back .

... 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 . ...

As of 1.3, the Apache source directories have been re-organised. This re-organisation is designed to simplify the directory structure, make it easier to add additional modules, and to give module authors a way of specifying compile time options or distribute binary modules. ... The non-module source files have moved from src into src/main . ... Configure . ... For example, say it is called mod_demo.c. The archive for this module should consist of two files, in a suitable directory name. ...
