After surviving its close encounter with our bright star, Lovejoy, the sun grazing comet, blazed a trail across southern skies at the end of December. Lucky for us it did, and even luckier that Stephane Guisard caught Lovejoy’s trip above the Andes on time lapse video (thanks to Discovery Magazine online). The comet is over 100 million kilometers from earth in this video and its tail is millions of kilometers long. That milky cluster of stars just off to the right of the comet? That’s our very own Milky Way galaxy. The reason we can see it from Earth is because we’re way out on one of the galaxy’s spiral arms, and we can look back towards its center.
