"Life in Extreme Environments: The Universe May Be More Habitable Than We Thought"

?Life in Extreme Environments: The Universe May Be More Habitable Than We Thought? is the ideal website for beginners in microbiology. The site is geared specifically for readers without previous knowledge of the subject. The writers for this site take the time to define technical terms. This works to make the information more readable for beginners. The site is also written in an interesting tone that drives readers to see what comes next. Scientific experiments are used to back up the belief that extreme microorganisms can survive in the harshest of climates on earth. The author makes a very good case for the possibility that life may exist on other planets. Some of these experiments revealed that water might have flown freely on Mars at one time. Also today many scientists believe water still flows on the red planet, only underground. Other experiments conclude that frozen lakes exist on one of Jupiter?s moons, Europa. These experiments make the argument for life on other planets not only interesting but also, valid. This website is a good source for students to identify extreme organisms and their characteristics. Also this site spends plenty of time on the environments in which these extreme organisms make their habitat. There are tables used for easy reference. Of these are the physical conditions in which extreme organisms can be found. One table gives examples of the different extremophiles found in different environmental parameters. These parameters include: Temperature Radiation Pressure Gravity Vacuum Desiccation Salinity PH Oxygen tension Chemical extremes This table along with others is easy to read and adds to the content of the site. This makes a good site for young students to learn from. Many scientific examples draw the reader further into the topic. The study of ?water bears? known as tartigrades is one of these examples. These bears can hibernate in temperatures ranging from -253 degrees Celsius up to 151 degrees Celsius. These bears can also be exposed to x-rays and vacuum conditions. This leaves the imagination open to how far life forms can survive living in extreme environments. These ideas push what is possible for surviving on another planet. The website is set up in a simple format. There are tables, pictures and the availability of a newsletter that can be sent to readers. All of these features add to the websites value. Technical terms are used frequently on the site and are defined to broaden the audience. This makes a good site for not only beginners of the topic but, also experts as well. With a simple design setup, the page loads quickly. There is only one requirement necessary to receive the full benefit from this site. An e-mail address will allow you to receive their newsletter. Complete computer novices should have no trouble navigating the site.
