spaceweb@oulu.fi - last update: 14 January 1999, 0950 UT (RR) . Term 'global change' is used to describe the changes of the large scale weather systems on Earth , and especially the surface temperature increase, by man-made increase of atmospheric CO 2 . ... It is the last point that is of importance for space physics, since it is possible that also the changes in Sun 's activity could be causing some changes in terrestrial climate. ...

... The Sun is the closest star to us, and a regular object in our Galaxy. Solar activity manifests itself, primarily, in solar flares - episodic explosive energy release in the form of electromagnetic radiation and high energy particles (electrons and protons). The nature of the flares is related to cyclic variations of global and local magnetic fields in the atmosphere of the Sun. ... Such formations are called active regions. ...

. The maps show thermal infrared radiation (heat) coming from Titan's surface at a wavelength of 19 microns, a spectral window at which the moon's otherwise opaque atmosphere is mostly transparent. Temperatures have been averaged around the globe from east to west (longitudinally) to emphasize the seasonal variation across latitudes (from north to south). Black regions in the maps are areas for which there was no data. NASA/JPL-Caltech/GSFC

... Since planets are expected to form out of the material in disks around young stars, the formation of a planet will thoroughly alter the structure of the circumstellar disk of their host star, forming significant gaps in the radial distribution of matter around the star. Additionally, processing of solids (annealing/crystallization) and changes in the overall gas/dust ratio are thought to happen during the planet formation process and are believed to alter the observational signature of the disk. ...
