What is the story about?
What's Happening?
Two newly discovered comets, C/2025 R2 (SWAN) and C/2025 A6 (Lemmon), are set to become visible in the night sky this October. Comet SWAN, discovered by amateur astronomer Vladimir Bezugly, will make its closest approach to Earth on October 19, while Comet Lemmon, discovered at the Mt. Lemmon SkyCenter in Arizona, will follow closely on October 21. Both comets are expected to be visible to the naked eye as they pass by Earth. SWAN will be visible in the Southern Hemisphere, while Lemmon will be best viewed in the Northern Hemisphere.
Why It's Important?
The appearance of these comets provides a unique opportunity for both amateur and professional astronomers to observe and study these celestial bodies. Comets are remnants from the early solar system, and their composition can offer insights into the conditions and processes that existed during its formation. The visibility of these comets to the naked eye also presents a rare chance for the general public to engage with astronomy and witness a cosmic event firsthand.
What's Next?
As the comets approach, astronomers will continue to monitor their brightness and trajectory. Observers in the Southern Hemisphere should look towards the western sky after sunset to spot SWAN, while those in the Northern Hemisphere can find Lemmon near the Big Dipper before sunrise. The comets' visibility will peak around their closest approach dates, providing optimal viewing conditions for skywatchers.
