Immense but tenuous and fleeting, the inner atmosphere or inner "coma" of comet Hyakutake is seen in this false color picture . ... Hyakutake's Hydrogen atoms were produced by the breakup of water (H20) molecules evaporating from its nucleus. The Hydrogen data, combined with other observations, indicate that this comet's nucleus, itself only a few km across, was producing about 7 to 8 tons of water per second. ...

The hotbed effect (hothouse effect) in the planets atmosphere is the inside atmosphere layers heating (of the Earth, Venus etc.), due to the transparent planet atmosphere for the main part of solar radiation (in optical range). In the atmosphere of the Earth this radiation is absorbed by the molecules of H2O, C02, O3 and others. ... As a result of human activities the CO2 content is increasing (and the other gases, absorbing in infrared range). ...

SPACE WEATHER . The response of our space environment to the constantly changing Sun is known as space weather. ... Some of the most dramatic space weather effects occur in association with eruptions of material from the solar atmosphere into interplanetary space. ... Space weather disturbances are generally caused by solar storms. ... the Sun. ... Every object in the solar system experiences the equivalent of Earth's space weather, although its detailed characteristics differ from place to place. ...

. ArtistтАЩs impression of an active volcano on Venus. Results from a long-term study of Venus find evidence of a clear injection of sulfur dioxide into its upper atmosphere. One possible interpretation is that volcanic activity increased the sulfur dioxide component of the upper atmosphere, although an alternative is that a change in atmospheric circulation dredged up the gas. // Credits: ESA/AOES

... Bojan Nikolic web pages home . ... The size of font used by PGPLOT for labels and other text on the plots can be changed using the PGSCH command, which takes one argument which is the relative height of the characters. If this argument is greater than one then to font size will be larger than default. ... The easy way to fix this is to call the PGVSTD command after the call to PGSCH. This command allows a sufficient margin for usual labelling, taking into account the current size of the font. ...

... As a result of BTA observations of 23 chemically peculiar stars with strong magnetic fields, it was found that in 22 of them the longitudinal magnetic field, measured from the hydrogen line cores are considerably lower (by about 1/3) than the value measured from metal lines in the same spectra. ...

Abstract: In recent years our observational knowledge of several important components of the central region of Centaurus A has increased dramatically: high resolution X-ray observations have revealed unprecedented detail in the jet and surrounding atmosphere; a kpc sized bipolar shell has been detected in the mid-IR; -rays have been detected in the GeV domain by Fermi and in the TeV domain by HESS. ...

... ABSTRACT From the equivalent widths ( ) of the selected Fell and Till lines the peculiarity indices P(FeII) and P(TiII) are determined for 70 normal B8-A8 stars of III-V luminosity classes and for 95 magnetic chemically peculiar (CP) B3-A8 stars. For normal stars all the P(FeII) and P(TiII) indices are within the limits of 0.5-1.7. ... They approach the values from >2 to 10-13 for the hot (He-weak), Si 4200 and Hg, Mn stars (Sp B3-B8, 18000 12000 K) , b) . ...

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. ...
