Skywatchers will have a rare opportunity to witness a once-in-a-lifetime comet passing by Earth this week. Comet Tsuchinshan-ATLAS was first spotted by astronomers in China at the Tsuchinshan Observatory on January 9, 2023, and later observed in South Africa using the ATLAS telescope. Comets, which are composed of dust and ice and have long tails, originated from the formation of the solar system billions of years ago. Most comets are not visible without a telescope, but Comet Tsuchinshan-ATLAS, coming from the Oort Cloud on the outer edge of the solar system, may be bright enough to be seen with the naked eye. This comet may not return to the solar system, as it could be propelled out by the gravity of other objects as it moves away from the sun. To catch a glimpse of Tsuchinshan-ATLAS, experts recommend looking on the night of October 9 when the comet will shine brightest due to forward scattering of light."Nichols emphasized that observing Comet Iibility is a rare opportunity not to be missed as they are not frequently visible. The comet will be visible to the naked eye starting from October 9 until the end of the month. For the best viewing experience, experts recommended finding a dark location with a clear view of the western horizon. If you prefer to observe the comet after sunset, it will be low in the sky near the setting sun. While it may appear faint during this time, using a telescope or binoculars can enhance the viewing experience. Although the comet may decrease in brightness after October 9, it will still be observable. Don't pass up the chance to witness this stunning comet, as it may not be visible again in your lifetime."
