Ambitious star gazers will get the once-in-a-lifetime chance to see a rare green comet tonight.
The comet, known as C/2022 E3 (ZTF) was last seen from earth roughly 50,000 years ago. It will fly within 45 million kilometres close to the earth. Due to its age, it is likely that the comet was last seen during the Stone Age when Neanderthals still roamed the planet.
The icy ball will emit a green glow in the sky due to ultraviolet radiation from the sun lighting up the gases surrounding its surface.
