... Views of Martian Clouds . ... Although not as pronounced as on Earth , clouds are common features on Mars. The Martian atmosphere has only a trace of water vapor; however, the temperature and pressure is such that the atmosphere is usually close to saturation and produces clouds. Even from Earth based telescopes, clouds have been observed by transient brightening on the surface of Mars. ... Lee waves . ... Wave clouds . ... Image Credit: Calvin J. Hamilton) . Lee Wave . ...

What will happen when the fragments hit Jupiter? ... All the fragments will enter Jupiter's atmosphere at an angle of 42 degrees from the vertical and impact near a latitude of 44 degrees south, but on the back side of the planet as seen from Earth (about 10 degrees in longitude behind the edge of Jupiter, as seen from Earth). ... Any body moving through an atmosphere is slowed by atmospheric drag, by having to push the molecules of that atmosphere out of the way. ...

... a positive central nucleus , where most of the atom's mass is concentrated, and . one or more negative electrons . Nucleus and electrons are held together by the electric attraction between positive (+) and negative (-) charges. ... When such processes occur in air, they produce there free ions and electrons, which can move and carry an electric current, something neutral atoms cannot do. ... The next heavier atom is that of helium (chemical symbol He) and it contains two electrons. ...

There is often dust associated with ionized regions. Compact HII regions usually have associated dust from a molecular cloud in which the massive star is being "born". ... For such stars the dust is not produced by the star, and a variety of dust features are observed. The planetary nebulae also usually have associated dust from the previous stage of evolution where they were either carbon stars or M-type giants. ... The feature near 11.5 microns in the IC 418 spectrum may be due to SiC dust. ...

... Magnetic Storms . ... The Earth's own magnetic field is probably created in the Earth's core, believed to contain molten iron, by a "fluid dynamo" . ... Jupiter . ... The magnetospheres of the giant planets differ from the Earth's in at least four ways. ... If Jupiter's magnetosphere has the same proportions, the solar wind would need 2-3 days to cover the corresponding distance (equal to about half the Earth-Sun distance!), during which the planet might have rotated 5-7 times around its axis. ...

... self-absorption - the absorption of light shining on an object by a process similar to that which produced the light originally; if a cloud emits less light than it absorbs from other clouds behind it, this net loss of light, termed self-absorption , causes the foreground cloud to appear darker than the background field (the term is from spectroscopy, where small absorption dips sometimes occur in larger emission lines, making the latter look as if it is absorbing part of itself) . ... HISA Main ...

... Solar flare activity is produced by the processes of accumulation and release of energy in an active region. ... In the framework of study of solar active regions, producing powerful flares the researchers from the RATAN-600 radio telescope have detected sources with features in the form of a sharp drop in the intensity of polarized radiation in various parts of the recorded frequency range (2-16GHz), sometimes changing the sign of polarization. ...

Emission Line Diagnostics in a ``No UV Bump'' Quasar PHL909 Smita Mathur, Belinda Wilkes, Martin Elvis and Jonathan McDowell Abstract PHL909 is a quasar with unusually low ultraviolet luminosity (blue bump strength C UV=IR = \Gamma0:20 compared to an average value of 0:4 (McDowell et al. ... The intrinsic continuum of PHL909 ( i.e. as seen by the BELR ) may thus be similar to the `standard' continuum, with a big blue bump, reddened along the line of sight. ...

These so-called noctilucent (night glowing) clouds (NLCs), are formed by sunlight reflecting off ice crystals high in the atmosphere, and usually appear in the northwest, through north to northeast during twilight in the late spring and summer months at our latitude. ...
