__**Triton's Atmosphere**__ [] Accessed on May 19, 2012 Audience: Adult The atmosphere of the Triton moon is made of thin nitrogen ice which makes up the thin clouds above its atmosphere. These same clouds can be seen in the image below. The website was last updated in 2011 by Calvin J. Hamilton and gives a lot of details on the moon as well as interesting pictures of the moons surface as well as all the data to go with it. Very easy to navigate and find your information and would reccomend it to anyone. This is a video showing the active ice volcanoes found on Triton producing the clouds of smoke.

__**Evidence of the Sun's light reaching Triton's surface**__ []Accessed on: May 19, 2012Audience: Teen-Adult.The website provides evidence that the sun is making it's presence felt on the Triton moon even though it is so far away. There is proof that their are seasons on the Triton moon but change a lot more slowly than Earth's. This wbsite gives you interesting facts about Triton that you couldnt find on every website and would be a good way to share something new with your classmates or to present on a powerpoint. It was last updated in 2010 and is quite easy to go through and find your facts. E. Lellouch, C. de Bergh, B. Sicardy are the authors of the page.

[]
 * This moon of Neptune was discovered by the British astronomer William Lassell in 1846. Since then it has been visited by only one spacecraft, Voyager 2, in 1989.
 * He also discovered Ariel and Umbriel, moons of Uranus. He was awarded the Gold Medal of the Royal Astronomical Society (1849), and the Royal Medal of the Royal Society (1858).

Neptune has thirteen known moons to date, Triton being the largest. William Lassell discovered Neptune and a few weeks later discovered Triton in 1846. Neptune is the 8th planet from the sun. NASA's Voyager 2 is the only spacecraft to fly past Neptune and Triton in 1989 and have found surface temperatures of -391°F (-235°C). This spacecraft has also found Triton has active ice geysers, making it one of the few geologically active moons in our solar system. Nearly the size of our moon, Triton has an atmosphere of mostly nitrogen.

__** New Horizons Detects Neptune's Moon Triton **__ [|__http://www.spacedaily.com/reports/New_Horizons_Detects_Neptune_Moon_Triton_999.html__] Accessed on: November 29, 2009 Audience:Teen- Adult. This website is interesting and is full of information about the spacecraft: New Horizons and Long Range Reconnaissance Imager (LORRI) detecting Triton during the annual spacecraft checkout in the fall of 2008. It is easy to follow and also provides information about the Triton like the diameter and the surface pressure. This website is up to date, and has quick information available to any user who would like to be up to date about how we are trying to get new information about far away planets and moons. For more detailed information about Triton, this website wouldn't be as useful as other websites would be.

__**Neptune's Moons**__ [] Accessed on: May 19, 2012 Audience: Teen-Adult. This website is up to date as recently as April 2012 and focuses mainly on the Neputnes largest moon Triton. The other moons Proteus and Nereid are the 2nd and 3rd largest moons respectively. While Triton was discovered by astronomer William Lassell in 1846 and Nereid in in 1946 by Gerard Kuiper.The other moons of Neptune weren't found until the space mission Voyager 2 was sent and discovered the other darker moons that werent visible. Mostly all the information we know about the Triton moon as well as the other Neptunian moons were all recorded on the Voyager two mission that stopped by for a visit in 1989. Very easy to navigate but if you are in dire need of exact information and details would consider researching other websites. The editor of the web page is named Phil Davis and works for NASA. [] Accessed on May 19, 2012 Audience: Teen-Adult. The Website gives insight on on the background behind the name of the moon. It gives you detailed images of the Voyager 2 space mission that was sent to investigate the planet Neptune and its largest moon Triton.The site talks about the features of the moon and how it is a retrograde moon meaning it rotates backwards. It is up to date as of 2011 and is gives you some helpful information in respect to the astronomer who found it and its characteristics. It gives you a little information not as much details though. The information seems accurate as it goes along with the rest of the other websites data on the Triton moon. It has no author. __**Astronomy for Kids**__ [|__http://www.kidsastronomy.com/neptune/moons.htm__] Accessed on November 29, 2009 Audience: kids 10 years +. This site is easy to navigate through. It was designed for kids to look at and get a better understanding of the sun, planets, the planet's moons, comets and asteroids. The information on the page isn't only about Triton though. The website talks about the four inner moons and four outer moons of Neptune. It seems a little out of date since it only mentions eight out of the thirteen known moons, but it still has an easy language that is more kid-friendly. This website will give reader the jist of the the main moons of Neptune, but any information about the newer discovered moons won't be available on here. __**The Moons of Neptune**__ [|__http://en.wikipedia.org/wiki/Triton_(moon)__]

Accessed on November 29, 2009 Audience: Teen- Adult This website was probably one of the most informational webistes I have seen. It has everything about the discovery of Triton, to detailed facts about the diameter, in both paragraph form and also a chart with everything laid out. I feel for every fact a student or interested user would need, it would be on this site. It is up to date and user friendly. There is a lot of information covered in the paragraphs of the page.
