If you like this sort of thing, it's a once in a lifetime opportunity to see this comet. Get yourself some binoculars!!! I'm certainly going to be looking at it.

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.
This icy cosmic passerby is painting a green streak across the sky until the first few days of February. You probably need binoculars to spot it, or even a telescope, under dark skies far from city lights.

Though green comets occasionally pass Earth, this one won't return for about 50,000 years, if ever. That's how long it takes Comet ZTF to orbit the Sun, which means that Neanderthals still walked the Earth when it last whizzed by, during the last Ice Age.
