Celestial Transition: Embrace the Autumn Equinox!
Mark your calendars for 2:19 PM EDT, when the autumnal equinox graces the skies! This magical moment signals the end of summer in the Northern Hemisphere, launching us into the vibrant colors and crisp air of fall. Simultaneously, our friends in the Southern Hemisphere bid farewell to winter and welcome the rejuvenating spirit of spring!
Gaze Up: The Double Cluster in Perseus Awaits!
As autumn unfolds, the night sky reveals one of its most dazzling displays: the Double Cluster in Perseus. This breathtaking celestial duo consists of NGC 869 and NGC 884, nestled just half a degree apart. To spot these stars, set your sights 4.5° west-northwest of the bright 4th-magnitude Eta Persei. Catch them around 10 PM local time as they stand 40° high in the northeastern sky.
Both clusters shine with a magnitude of around 4, making them perfect candidates for an enchanting night of stargazing. Whether you're using binoculars or a telescope, you'll find a stunning view. NGC 869, the richer of the two, boasts more visible stars, while NGC 884 is home to the magnificent RS Persei — a fluctuating red supergiant that varies in brightness from 8th to 10th magnitude, truly a sight not to be missed!
