Moon to Dance Near Antares: Watch on August 30-31
Skywatchers can look forward to a remarkable celestial event on the nights of August 30 and 31, 2023. The nearly half-lit moon will glide past the bright red supergiant star, Antares, located in the constellation Scorpius. This event offers a unique opportunity to observe two significant astronomical bodies in close proximity.
On the evening of August 30, the moon will be positioned approximately 20 degrees above the southwestern horizon at sunset. Antares will appear as a vivid red point of light, situated about 5 degrees to the upper left of the moon. For reference, the width of three fingers held at arm’s length represents about 5 degrees in the night sky, while a clenched fist measures roughly 10 degrees.
The moon will reach its first quarter phase at 2:25 a.m. (0625 GMT) on August 31. At this moment, the right side of the moon will be fully illuminated, revealing the ancient basaltic plains of Mare Serenitatis and Mare Tranquilitatis. In contrast, the left side will be shrouded in darkness, enhancing the visual interest for observers and photographers alike.
Viewing Opportunities and Equipment Recommendations
By sunset on August 31, the moon will shift to the left of Antares. This star is one of the brightest visible in the northern hemisphere and is often referred to as the “heart of the scorpion” due to its central position in the constellation. Interestingly, Antares is a binary star system, comprising a red supergiant and a white main-sequence companion, though the light from the red giant dominates its appearance from Earth.
For those eager to explore the lunar surface more closely, the Celestron NexStar 8SE telescope is an excellent choice for beginners. It offers reliable and quick views of celestial objects, making it a favorite among amateur astronomers. Enthusiasts can find in-depth reviews and further information on this telescope for optimal viewing experiences.
After passing Antares, the moon will continue its eastward journey, traversing through the constellations of Sagittarius, Capricornus, and Aquarius as it approaches its full moon phase on September 7. This full moon will coincide with a total lunar eclipse, where Earth will align directly between the moon and the sun, casting a shadow on the lunar surface and potentially creating a striking blood moon effect.
For photographers keen on capturing the beauty of the lunar eclipse, guidance on imaging techniques is available. Additionally, those considering upgrades to their astrophotography equipment can consult various roundups of the best cameras and lenses tailored for capturing celestial events.
This astronomical phenomenon promises to be an engaging spectacle for both seasoned astronomers and casual skywatchers alike, inviting everyone to step outside and enjoy the wonders of the night sky.
