    Hubble captured an eclipse on Uranus, as the icy moon Ariel cast its shadow onto the planet?s cloudy atmosphere. It?s the first such eclipse viewed. Uranus orbits the Sun so slowly that a single season lasts 42 years. On the opposite end of the spectrum, Hubble found a planet that orbits its star every 10 hours. The Jupiter-size planet, 3000 degrees Fahrenheit in temperature, is extremely close to its star. Hubble has found a rare example of a galaxy under construction. A recent image shows a group of smaller galaxies merging into a massive galaxy over 10 billion years away. Astronomers believe this is how today?s galaxies formed.
