Have you seen comet Tsuchinshan-ATLAS yet? If you haven't yet seen the bright, icy space rock that's traveled from the edge of the solar system, it's not too late. But you need to see it soon.

The best comet of the year is starting to fade in brightness, but it’s still an easy naked-eye object in the evening sky.

The ancient comet—dubbed the "comet of the century"—returns to the inner solar system only once every 80,000 years.
