... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...

... The data inside CHAMELEON is organized in tables (e.g. ScanTable), structures (e.g. GenConfig), arrays of structures (e.g. scans), and plain arrays (e.g. VisSq). ...

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. ...

Next: A Preliminary Investigation Up: Spatial Corrections of ROSAT Previous: Introduction . ... These tasks bin a time sorted photon event list based on an assigned phase that corresponds to the 402 second period of the wobble. ... The fundamental limitation of this method is how many source counts you have for centroiding each binned image section. ... Once the phase binned qpoes have been shifted in x,y so as to align the source centroid, they are restacked using 'qpappend_ftsi'. ...

... The remote area was formed very early, at a time when the Universe was a fifth of its present age and the presence of the galaxy string defies existing models, which can not explain how a string this big could have formed so long ago. ... The simulations tell us that you cannot take the matter in the early Universe and line it up in strings this large," Dr Francis said. ... But in the early Universe, most galaxies had not yet formed, and most dark matter clouds will not yet contain a galaxy. ...
