New Images Hint at Wet and Wild History For Europa . Chunky ice rafts and relatively smooth, crater-free patches on the surface of Jupiter's frozen moon Europa suggest a younger, thinner icy surface than previously believed, according to new images from Galileo's spacecraft released today. ... These features, which lend credence to the idea of hidden, subsurface oceans, also are stirring up controversy among scientists who disagree about the age of Europa's surface. ... Europa . ...
Through Thick and Thin In this Thread, we will discover how a given amount of light changes in intensity when the area it shines on changes.We will also make a final observation about the change in light and heat that happens when we tilt towards or away from the Sun. This explains why things seem less warm during the winter months, when the section of Earth we live on is tilting away from the Sun. ... Different amounts of the paper get covered with light when the flashlight or paper is tilted. ...

... Apply a time-varying phase shift to track the object. ... This overrides the normal behaviour of using the spin axis. arcane The format for the pmotion text files is the "arcane" format (see below). ... Each source is specified by three numbers: ra dec flux The RA and DEC are in normal Miriad format, and the flux is in Jy. ... The normal format consists of 3 values per line, being time ra dec with "time" (UTC), "ra" and "dec" being the position of the object at a given time. ...
