Stunning image reveals ‘3 days in the life of a comet’ (photo)


A brilliant green comet has already produced some amazing imagery as it speeds toward its closest approach to Earth next month.

Comet C/2022 E3 (ZTF) was discovered by astronomers at the Zwicky Transient Facility (ZTF) at the Palomar Observatory in California in March 2022, when it was 399 million miles (643 million kilometers) from the sun, just inside the orbit of Jupiter. The comet’s long orbital period (the amount of time it takes to complete one orbit of the sun) means that C/2022 E3 (ZTF) hasn’t been seen from Earth in some 50,000 years.
