Skywatchers in Portugal will have the opportunity to observe a rare planetary alignment over the coming days, as six planets become visible in the evening sky in an unusual celestial display. The phenomenon follows growing interest in astronomical events this year, including a solar eclipse scheduled for August.
According to international space agencies, the alignment is not a perfect straight line in space but rather a visual effect created Earth’s perspective. The planets orbit the Sun on slightly different planes, yet from our viewpoint they appear distributed along the ecliptic, the imaginary path across the sky that the Sun, Moon and planets seem to follow.
There is no single fixed date for the event. Astronomical publications indicate that the planetary alignment will unfold gradually from the final days of February into early March. While some references highlight 28 February as a key viewing moment, experts recommend observing the sky throughout this broader window to maximise visibility, depending on local weather conditions.
The six planets expected to be visible are Mercury, Venus, Saturn, Jupiter, Uranus and Neptune. Not all will appear with the same brightness or clarity. Mercury, Venus, Saturn and Jupiter can typically be seen with the naked eye under clear skies, particularly away from strong urban light pollution. Jupiter will be one of the easiest to identify due to its brightness. Uranus and Neptune, however, are significantly fainter and will require binoculars or a telescope for proper observation.
The best time to witness the alignment will be shortly after sunset. Observers are advised to focus their gaze toward the western or west south eastern horizon. Clear skies and minimal atmospheric haze will improve viewing conditions, especially in coastal or rural areas of Portugal where artificial lighting is less intense.
Astronomers note that while alignments of two or three planets are relatively common, seeing as many as six within the same general region of the sky is less frequent and therefore attracts greater public attention. The event provides an accessible opportunity for amateur astronomers and families to engage with night sky observation.
Safety precautions are also recommended. Anyone using binoculars or telescopes should wait until the Sun has fully set before directing optical equipment toward the horizon, as looking at or near the Sun can cause serious eye damage. Proper positioning and gradual adjustment of focus will enhance clarity once darkness increases.
With favourable weather conditions, the coming evenings offer a rare chance for residents across Portugal to witness multiple planets sharing the same stretch of sky in a visually striking display.
