Changing a World . What did the students learn from all this? ... The students found this unsatisfactory -- some of them would not be able to fit another astronomy class into their schedules, but they wanted to know about our planetary neighbors, and this project gave them the opportunity to find out without spending valuable class time on the subject. ... The students also learned to learn for themselves, perhaps one of the most important milestones during formal education. ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

... 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. ...
