Glad I didn't have your job of picking for this list. It had to be a tough call on whether to list Phoenix or exo-planets as number one. As usual, great article. The artist rendition you picked to accompany the entry for Cassini was a real eye catcher. I can only imagine what it would be like to stand on Enceladus and see Saturn like that. You left UT off the list. It doesn't matter how good the science is if somebody doesn't get the word out. You do a mighty fine job of that.
