Beware the Ides of Mars (Video)

Don't take your eyes off the mesmerizing comet 2013Al, hellbent on colliding with Mars this month. Will it or won't it crash into the red planet? There's a 1 in 600 chance right now. To see what that would look like, click on scientist Leon Elenin's fabulous video simulation below.

As for me, I just returned from Lake Tahoe, where I skied on a frozen lake under the stars.  Now, more than ever, I've been staring up into the skies. I've wanted to fly into space since I was a little girl. That's just another form of wanderlust. No wonder I can't stop listening to Grace Potter's sad, lovely song "Stars." Play it next time you want to soar over the earth.
