Missed last week's comet? At twilight on Tuesday the comet called Pan-STARRS will be visible in the Northern Hemisphere above the western horizon - right next to the crescent moon.
The glare of the setting sun might make it hard to see the comet with the naked eye, says California astronomer Tony Phillips, the slender moon will be "super beautiful."
Star-gazers, remember your binoculars, but be certain not to point them at the setting sun.
Pan-STARRS is making its first-ever cruise through the inner solar system. It passed within 28 million miles of the sun Sunday.
Next week, the comet should be easier to spot.
