Astronomers observed a rare “green comet” on Wednesday from Greece as it passed over their hilltop observatory, with astronomer Alkisti Bonanos of the National Observatory of Athens saying it was at its brightest that night. The comet, which had been lurking in the night sky for months, passed by at a distance of about 42.5 million kilometres. The last time it was seen was about 50,000 years ago when Neanderthals still inhabited Eurasia, Ice Age mammals roamed the land and northern Africa was a fertile and rainy place. The comet’s greenish hue comes from its chemical composition of diatomic carbon and cyanogen. Bonanos said the comet has a velocity of 57 kilometres per second. Gianluca Masi, an astronomer from Rome, also observed the comet early Thursday, and shared images of the celestial object from virtually-controlled telescopes in Italy and Spain. While he said the bright moon affected observations, the images still showed the glowing comet as it passed by the Earth.

The “green comet” was last in orbit 50 thousand years ago and after its orbit close Earth, it likely won’t come back into orbit for several million years. So here’s what you need to know if you want to try and see the comet between now and February 1: The darker, the better! First things first, you need to get to get away from city lights. Try and find a dark place away from light pollution. Have the right gear While you may be able to see the comet from the naked eye if conditions are just right, your best chance to see it is through binoculars or a telescope. Timing is everything The comet will be competing with the moon’s brightness so look up after the moon has set…which means after midnight, in the video published on Jan 24, 2023, by WUSA9, as “The Green Comet: How it got named and how to see it“, below:
A green-hued comet that has been lurking in the night sky for months is expected to be the most visible to stargazers this week as it gradually passes Earth for the first time in about 50,000 years. It will pass by our planet at a distance of about 26.4 million miles per hour. Nicknamed “dirty snowballs,” comets are balls of ice, dust and rocks typically from the ring of icy material called the Oort cloud at our solar system’s outer edge.

A recently discovered green comet passed Earth for the first time in 50,000 years. It was last visible in the night sky during the Stone Age.
