One study, in the journal Icarus, shows that hydrogen gas flowing throughout the planet's atmosphere disappears at the moon's surface. This phenomenon led to the suggestion that perhaps alien forms were breathing hydrogen. In the Journal of Geophysical Research, a study found that there was a lack of hydrogen on the surface of Titan and also proposed the possibility of hydrogen being consumed by alien life. Chris McKay, a NASA astrobiologist who led the research, stated, "We suggested hydrogen consumption because it's the obvious gas for life to consume on Titan, similar to the way we consume oxygen on Earth." The media commotion was perhaps started with the Telegraph's attention grabbing headline "Titan: NASA scientists discover evidence 'that alien life exists on Saturn's moon'". However, representatives from NASA were quick to put the brakes on the hysteria by noting that alien life on Titan is one of many possible explanations. The headlines may have jumped the gun by announcing alien life on Titan, but as McKay notes, "This is still a long way from 'evidence of life'. However, it is extremely interesting." The first link leads to an article from USA Today, which provides more details on the new studies published about Titan. The second link gives readers a chance to read the Telegraph's article that generated all the excitement. The third link leads to a blog entry from Scientific American where Chris McKay attempts to clarify the research and claims of extraterrestrial life. The fourth link will take visitors to a piece from the BBC on the beauty of Saturn. The fifth and sixth links are from NASA. The first is a wondrous slide show of Saturn with some amazing images and the second allows visitors to listen to radio emissions from Saturn. For the full effect, Scout recommends turning off the slideshow sound and listing to the radio emissions while watching the slideshow. The last link will take visitors to the National Earth Science Teachers Association's (NESTA) website, Windows to the Universe Saturn. Here, those wanting to know more about Saturn can find a wealth of information about the ringed planet including planetary facts, myth and culture, and space missions.
