... Tonight's Sky . ... Surface features on Titan form like Earth's, but with a frigid twist . ... Wind, rain, volcanoes, tectonics, and other earthlike processes all sculpt features on Titan's complex and varied surface in an environment more than 212ТА Fahrenheit (100ТА Celsius) colder on average than Antarctica. It is really surprising how closely Titan's surface resembles Earth's," said Rosaly Lopes, a planetary geologist at the Jet Propulsion Laboratory (JPL) in Pasadena, California. ...

In this method the fields outside and inside a particle are represented by expansions in term of proper basis functions (practically always the vector spherical harmonics). Since the particle surface does not coincide with the coordinate surface, it is impossible to satisfy the boundary conditions exactly, and the expansions are limited by a finite number of terms, and the boundary conditions are considered in a finite set of points (matching points). ...

... We employ Stokes I and V LSD profiles of the co ol magnetic Ap star CrB, extracted for the elements Ti, Cr, Fe and Ba, to confirm systematic element-toelement differences in the longitudinal field variation of this star. ... 5 Mo deling the phase variations The longitudinal field and equivalent width variations of CrB potentially provide a useful method to probe the surface abundance distributions of this and other slowly-rotating magnetic stars. ...

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. ...

... Bad Astronomy . ... Bad Astronomy : The seasons are caused by the change in the distance of the Earth to the Sun. ... The change in distance of the Earth to the Sun is a very minor player. ... Well, not completely wrong; certainly the Earth's distance from the Sun has something to do with the temperature, but it is a relatively minor effect. ... Basically, the temperature depends only weakly on distance changes; the temperature goes as the inverse square root of the distance of the planet to the Sun...
