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

A rare celestial event is lighting up the night sky this month as Comet Tsuchinshan-Atlas makes its closest approach to Earth for the first time in roughly 80,000 years.
