A rare green comet is passing Earth, and this could be humanity's last chance to see it. Stunning photos reveal what you might see if you look to the pre-dawn skies and spot the ball of frozen gas and dust shooting past this week.

Formally, the comet is called C/2022 E3 (ZTF), named for the Zwicky Transient Facility, which first discovered it in March. But skywatchers call it Comet ZTF for short.
