APOD 2.2

Orange Sun Oozing:
This video clip was taken over an hour showing how rapidly the sun's surface changes. The clip was directed over a sun spot, dramatizing the rapid motion. At first the video seems natural and relatable because it looks like a lava flow that would occur on Earth. There is a definate churning of molten liquid occuring. The amazing part is that the retively small sized dots, a granule, that rapidly shape shift or dissapere are the size of Earth's continents. That is hard to wrap around in my mind, that something that big can be completely molded in an hour. It is really cool to actually see the sun up that close and see it in motion rather than just a still frame.

Jupiter Near Opposition

See Explanation.  Clicking on the picture will download
 the highest resolution version available.
Jupiter is near opposition, which is when it is opposite of the sun. It is also closest to Earth at this time of the year, allowing this stunning shot using a 1 meter telescope. Jupiter has a stormy cloud like atmosphere creating strips of different collored swirling clouds. The two dots one above and one to the left are two of Jupiter's biggest moons. Io is the one to the left and is extremely volcanic and has many sulfuric geysers. The other moon is Ganymede, known for its icy surface. It also has a atmoshere simulare to Earths. Scientists believe that under the ice is an huge body of water. These are two of the four moons Galileo saw in his observations. This picture interested me because my research project is on Jupiter's moons so it cool to see more pictures of Jupiter and its moons now that I know more about them.
