This weekend promises to be a spectacular one for stargazers, as the planets Venus and Jupiter align in the evening sky. With both heavenly bodies becoming increasingly prominent, this celestial event is set against a backdrop of darkening skies, thanks to the waning Flower Moon. This unique combination will create ideal conditions for astronomers and casual sky watchers alike.

As dusk falls, both Venus and Jupiter will be visible in the western sky, with Venus emerging as a particularly bright presence. Known as the “Evening Star,” Venus is rapidly increasing in brightness, while Jupiter continues to shine as one of the most luminous objects after sunset. For those eager to witness this planetary event, the conjunction of these two planets is due to take place on June 9, making it a must-see attraction for astronomy enthusiasts.
This weekend presents an excellent opportunity for stargazing due to the lesser illumination from the moon. The Flower Moon, which reached its full phase recently, is now in its last quarter, resulting in darker skies that will enhance visibility for observing celestial phenomena. Therefore, whether one is stepping outside for a brief glance post-dinner or planning an extended evening of stargazing, the cosmos is truly putting on a show.
The northern lights, or aurora borealis, may also make an appearance during this time, particularly in higher latitudes such as Alaska, Canada, and parts of the northern United States. Geomagnetic storms, resulting from charged particles emitted from the sun interacting with the Earth’s atmosphere, can produce these stunning displays of light. The best opportunities to catch a glimpse of the auroras are expected late on the night of Friday, May 8, and into the early hours of Saturday, May 9, when geomagnetic activity is anticipated to peak.
According to the National Oceanic and Atmospheric Administration (NOAA), conditions for viewing the northern lights are expected to reach “active” levels during this time, as effects from a coronal hole high-speed stream impact Earth’s magnetic field. Although the intensity of these storms is not expected to reach severe levels, there may be intermittent bursts of activity that produce visible displays, especially during the darkest hours of the night.
For optimal viewing of Venus and Jupiter, observers should head outdoors approximately 30 to 45 minutes after sunset. The best locations will be those with a clear, unobstructed view of the western horizon, away from city lights. Venus will feature a more striking brightness, while Jupiter will shine nearby with its steadier golden-white glow. Fortunately, both planets are easily visible to the naked eye, though binoculars can enhance the viewing experience by providing clearer and more vivid detail against the darkening twilight.
In addition to the conjunction of Venus and Jupiter, this weekend provides an excellent opportunity to stargaze for spring constellations such as Ursa Major, Boötes, Leo, and Cancer. Clear skies will significantly enhance visibility, making this an ideal weekend for both novice and experienced stargazers.
Should the northern lights become visible, viewers are advised to find a secluded dark area with a clear view of the northern horizon. The darker the environment, the more vibrant the colours of the auroras will be. Real-time forecasts, such as NOAA’s 30-minute aurora predictions, can also be helpful in tracking solar wind patterns and magnetic field changes that influence auroral visibility.
In summary, with Venus and Jupiter drawing closer together in the evening sky, and potential displays of the northern lights enhancing the experience, this weekend is set to be a breathtaking showcase of cosmic beauty. Whether a passionate astronomer or a curious casual observer, the skies are inviting you to look up and enjoy a spectacular weekend of stargazing.
