Sky Spectacles: Two Comets Light Up the Night

In October 2025, the night sky puts on a rare show with two comets visible to the naked eye. Comet Lemmon and Comet SWAN are making their closest approaches to Earth, offering a unique opportunity for stargazers. Comet Lemmon, discovered in January 2025, is expected to shine brightest around Halloween. It will be closest to Earth on October 21, but its brightness will peak later in the month. Comet SWAN, discovered in September 2025, is also visible but slightly dimmer. It is best viewed from the Southern Hemisphere. To spot these comets, find a dark spot away from city lights. Look to the northwest for Comet Lemmon and to the southwest for Comet SWAN. Both comets will be visible in the evening sky, but their exact positions will change each night. This celestial event is a rare treat. Comet Lemmon won't be this close to Earth again for about 1, 150 years. So, if you miss it this time, you'll have to wait a long while for another chance. While enjoying the comets, you might wonder about Halley's Comet, the most famous of all. It last appeared in 1986 and will return in 2061. Unlike the current comets, Halley's Comet is visible roughly every 76 years.
