Before you continue reading, you should know that this was not always the case, i.e. the Moon once was rotating with respect to the Earth, so that on every night a terrestrial observer (if there was one, because this was long, long before mankind appeared on our planet, and even before any major animals had appeared) saw another face of the Moon. ... Figure 1 (not to scale) shows how we can imagine the system Earth-Moon...

... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....

... At hard energies (3.5-7.5 keV), we detect a nearly circular shell of outer radius 2.8 (13 kpc). ... We find that the observed density and temperature jumps are consistent with a Mach M 1.2 shock (for monoatomic gas with = 5/3). ... Key words: Galaxy; X-ray ; M87. clusters (kT 3 - 10keV). ... These weak shocks, if there is sufficient viscosity, can provide sufficient energy to maintain the thermal energy of the gas in the cooling core of the Perseus cluster (see detailed studies including [8, 7]). ...
