APOD 2.7

For this week, I chose an APOD entry depicting Titan's lake-filled land. Titan is Saturn's large moon. I remember learning about Saturn during the solar system presentions in class and from this entry I learned that Titan,besides earth is the only unique world with stable liquids on its surface. I was intrigued by this because I had never truly grasped the idea that other objects in our solar system could have that.

APOD 2.6

This week's chosen APOD depitcs the bright source of gamma rays that is Earth. This image was taken from a gamma-ray telescope orbiting around earth in space. I chose this picture for this week because I remembered what we learned in class about telescopes and light rays. The telescope that took this image is called the Fermi Gamma-ray Space Telescope which recently celebrated its 2000th day in orbit. I thought this picture gave an interesting depiction of the bright souce of gamma rays on Earth and I also liked looking at the different intensities these rays had.
