A team of U.S. and German astrophysicists have made the first ever detection of X-rays coming from a comet. ... Following the initial detection, the team reported repeated X-ray emissions from the comet over the next 24 hours. ... One preliminary theory is that X-ray emission from the Sun was absorbed by a cloud of gaseous water molecules surrounding the nucleus of the comet, and then were re-emitted by the molecules in a process physicists call "fluorescence." ...

... The vast quantities of data produced by modern radio telescopes have outstripped conventional visualization techniques available to astronomers. ... While visualization techniques in other areas find some application in astronomy, problems peculiar to the field require new techniques, such as methods for identifying three-dimensional regions. ... By presenting data three dimensionally, the astronomer may identify structure in the data which is not obvious when using conventional tools. ...
