At 1:30am EDT on Monday, Curiosity will attempt to land on Mars — no easy task as NASA’s “Seven Minutes of Terror” video shows. If you want to really celebrate, you can head to Times Square to watch it on the giant Toshiba Vision Screen or catch it at any one of these events across the country.

这颗一度被认为将遭遇灭顶之灾的Lovejoy彗星,在与太阳亲密接触之后,奇迹般的幸存下来,并且又长出了新尾巴,依旧在夜空炫耀着它的美丽身姿!当时Lovejoy彗星距离太阳表面仅12万公里,承受了5700度的高温,尾巴被蒸发掉一大半。
