If you're an amateur astronomer, you've likely been tracking Comet PanSTARRS for a while now. Visible in the night sky — at least in the Northern Hemisphere — since March 12th, PanSTARRS has had astronomy enthusiasts dusting off their binoculars for weeks already.
But like that kid who always bested you at the science fair, NASA has decided to share their perspective on PanSTARRS. Courtesy of the Heliospheric Imager (HI), an instrument used to monitor the Sun for coronal mass ejections, this is a sight not to be missed. On the right, and labeled for our convenience, floats the planet Earth.
For perspective, the HI sits roughly 100 million miles from Earth and the tail of Comet PanSTARRS is ten times as long as the Earth is wide. On the left hand side of the video, you'll see the edge of the Sun.
By the way, there's still time to catch a glimpse of PanSTARRS, if you're lucky. The comet is most likely visible in the early evening sky, before the moon rises. PanSTARRS appears like a glimmering exclamation mark near the horizon and is close to the Andromeda Galaxy on your star map.
