A rare and fascinating event is currently taking place in the skies over Australia, as a green comet that hasn’t been seen in over 50,000 years makes its way through our solar system. This is a once-in-a-lifetime opportunity for astronomers and stargazers alike to catch a glimpse of a celestial object that has been long forgotten.

The comet, known as C/2019 Y4 (ATLAS), was first discovered in December 2019 by astronomers using the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Hawaii. Initially, it was predicted to become one of the brightest comets in decades, visible to the naked eye from Earth. However, the comet has since gone through unexpected changes, and it is not as bright as originally predicted.

Despite this setback, the green comet is still visible in the night sky from parts of Australia, and it is a sight to behold. The green color of the comet is caused by the presence of diatomic carbon (C2) molecules, which fluoresce in sunlight and give off a green glow. This is a relatively rare phenomenon for comets, making C/2019 Y4 (ATLAS) all the more special.

This is a last-chance opportunity to observe the green comet, as it will not be seen in our solar system again for another 50,000 years. Astronomers and stargazers are encouraged to take advantage of this rare event and observe the comet while they still can.

In conclusion, the sighting of the green comet C/2019 Y4 (ATLAS) is a rare and exciting event that is currently taking place in the skies over Australia. This comet hasn’t been seen in over 50,000 years and is a once-in-a-lifetime opportunity for astronomers and stargazers to catch a glimpse of a celestial object that has been long forgotten. With its striking green color, this comet is a fascinating sight to behold and a reminder of the vast and mysterious universe that surrounds us.
