This comet last visited Earth before Jesus was born – Green Comet was here 50,000 Years ago😱

This week, stargazers will be treated to a rare sight in the sky – a green comet that is expected to be the most visible to us in about 50,000 years. Last time the comet was this close, Neanderthals (stone age people) still inhabited Eurasia, our species was expanding its reach beyond Africa, and ice age mammals like mammoths and saber-toothed cats roamed the land. Northern Africa was a wet, fertile and rainy place.

Comets are made up of a solid core of rock, ice and dust, and a thin gassy atmosphere of more ice and dust, known as a coma, surrounds it. Astronomers at Caltech’s Palomar Observatory in San Diego found the green comet in March 2022 using the Zwicky Transient Facility telescope. Its green hue reflects the comet’s chemical composition, which is the result of a clash between sunlight and carbon-based molecules in the comet’s coma.

NASA researchers are taking this pit stop as a chance to gather everything they can about the comet. They will be looking for the fingerprints of given molecules that they can’t access from the ground, such as water, carbon dioxide, carbon monoxide and methane.

What else should we expect from outer space. Are there more “once in a million years” comets out there – perhaps on a collision course with Earth? Who knows?

Anyway,if you have a pair of good binoculars handy, you’ll be able to see the comet during a clear night in the northern sky. It is important to find a remote location to avoid light pollution. The comet will be visible from mid-April to late May.

What do you think?
