Titan

The photograph you are looking at right now is a picture of Saturn and some of its moons, my information is regarding the moon Titan. Titan was discovered by a Dutch mathematician and Physicist Christian Huygens in 1655. Titan is Saturn's largest moon, and is the second largest moon in the solar system. It is orbits Saturn every 15-16 days from a distance of 1,221,830 km. Currently there is a mission to saturn and its surrounding planetary objects known as the Cassini-Huygens mission. More directly the Huygens probe was released and descending into Titans atmosphere while gathering important data. Through this scientists hope to discover many things about Titan, and also because of its unique atmosphere discover what the earth may have been like thousands of years ago.

The large streak is a bleed of the photo coming from the light of saturn which is located under it. The dots around it are the moons of Saturn the largest one in the top left of the photo is Saturn's moon Titan. There are two other moons to the left of Saurn the top on being Tethys and the bottom one Dione. The small dot to the right on the top is the moon Hyperion and the one directly to the right of Saturn is Enceladus. This is only one of four images that supposed to be taken one hour apart from each other; however there was a miscommunication and they were taken one minute apart. The purpose of the project was to hopefully see movement of the moons around saturn. However, the time increments of the photos were insufficient because I was not able to see any movement. In order to see any motion the time increments would have to be increased. The linear size of this is 570,000 km.
