Stargazers across North America will have a unique opportunity to view a striking celestial alignment on the evening of January 22, 2024. As twilight deepens, a crescent moon will appear just below the planet Saturn, creating a visually captivating sight shortly after sunset.
The moon will be approximately 17% illuminated, making it bright enough for easy visibility. This crescent moon will also allow for subtle “Earthshine,” a phenomenon where sunlight reflected from Earth illuminates the moon’s night side. As Saturn begins to fade from evening skies, this alignment presents one of the last chances for observers to catch a glimpse of the ringed planet before it moves closer to the sun’s glare.
To view the moon and Saturn, look towards the west-southwest horizon about 30-60 minutes after sunset. Both celestial bodies will be positioned low in the sky, making timing and a clear line of sight essential. The moon will appear approximately six degrees beneath Saturn, roughly the width of three fingers held at arm’s length.
The moon will shine as a slender crescent, while Saturn will resemble a steady, pale golden star, easily outshining its twilight surroundings. For those seeking to enhance their viewing experience, binoculars can help reveal the Earthshine on the moon’s night side.
Upcoming Celestial Events
The alignment on January 22 is the second of three consecutive nights when the moon and Saturn will appear close together, with this particular night offering the most balanced view. The two will hang in a diagonal formation, making it a picturesque sight for both amateur and seasoned astronomers.
For those using telescopes, Saturn’s rings will still be visible, although they will appear to fade as the planet drops lower in the sky. On the following evening, January 23, observers can expect to see a 26%-lit waxing crescent moon positioned above Saturn, providing another chance to appreciate this celestial pairing.
As Saturn approaches its annual solar conjunction on March 25, it will gradually recede from evening view. After this date, the planet will emerge into the pre-dawn sky before transitioning back into the evening sky, culminating in its opposition on October 4.
This series of celestial events offers a prime opportunity for sky watchers to appreciate the wonders of the universe. Clear skies and keen eyes will enhance the experience for all who take the time to observe this enchanting pairing of the moon and Saturn.
