This week, stargazers are in for a treat as a remarkable celestial display is set to unfold in the evening skies. The trio of the waxing crescent moon, the dazzling planet Venus, and the bright star Spica will be visible to those willing to glance upwards at the right time. This celestial spectacle begins on Monday, August 17, and continues to delight until the moon shifts away from its companions by August 20.

Observers are advised to look for the cosmic trio about 40 to 50 minutes after sunset. During this time, the crescent moon, approximately 30% illuminated, will conveniently position itself in close proximity to Venus and Spica. All three objects will be visible low in the western sky as the twilight deepens. EarthSky.org suggests that viewers will be treated to an enchanting sight as the trio will soon set after nightfall.
As the week progresses, the moon will gradually move eastward. On Tuesday, August 18, the crescent moon will increase in illumination to approximately 40% and will have shifted slightly further away from Venus. Spica will remain nestled between the two celestial bodies, creating a picturesque view that is well worth the effort of stepping outside.
By Thursday, August 20, the moon will have ventured away from Venus and Spica to align with the prominent star in the Scorpius constellation. Stargazers should take note, as this nearly 60%-illuminated moon will sit close to the deep red star, generating a gorgeous sight shortly after sunset. These pairs of celestial bodies will be especially close together before vanishing below the horizon in the middle of the night.
It is important to highlight that while the Perseids meteor shower may have recently stolen the limelight, residual meteor activity could still grace the skies until approximately August 24. NASA has praised the Perseids as “the best meteor shower of the year,” known for producing bright meteors that often leave behind colourful wakes.
For those hoping to enjoy this stunning display, it is essential to find a location that offers a clear view of the western horizon. Observers in the Northern Hemisphere will have the best experience, as Venus continues to shine brightly throughout August. However, vegetation, buildings, or mountains can obstruct visibility, making it crucial to seek unobstructed vantage points away from urban light pollution.
The moon, Venus, and Spica can be viewed with the naked eye, although binoculars may enhance the sight of Spica, which may be less prominent against the backdrop of the twilight sky. To make the most of this celestial event, skywatchers should be prepared to look skyward during the golden moments just after sunset.
As this week unfolds, the stars will continue to captivate enthusiasts and casual viewers alike. Whether you are a dedicated astronomer or simply a curious bystander, this celestial event promises to be a show not to miss. So be sure to don your outdoor attire and set aside a few moments to gaze upon the wonders of the universe that will grace the skies.
