Skywatchers could be treated to a rare double feature this October as two comets — C/2025 R2 (SWAN) and C/2025 A6 (Lemmon) — are forecast to brighten around the same time.

That coincides with the peak of the Orionid meteor shower and the new moon, setting the stage for potentially one of the most impactful celestial displays in years.
