Astronomers are excited about a rare opportunity to witness a group of planets aligned in the night sky at the same time. According to Dr. Rebecca Allen, co-director of Swinburne University’s space technology and industry institute, this alignment is only possible due to the unique positions of the planets.
The most visible planets will be Venus, Mars, Jupiter, Saturn, and Neptune, which are aligned on the same side of the sun within the same degree in the sky. This rare event allows viewers to see multiple planets at once, especially those farther away from the sun like Neptune.
On January 21, stargazers can expect to see these planets clearly in the night sky. Venus will be visible as a bright and easily seen “morning star” or “evening star,” while Mars will appear particularly clear due to the alignment with the sun behind it.
With a telescope, viewers can also observe Saturn’s rings and Jupiter’s surface features. The Astronomical Society of Victoria notes that four of the planets are like beacons, easily visible on a clear night around 9:45 pm, including Venus and Saturn, followed by Jupiter and Mars later.
The alignment is also an excellent opportunity to spot satellites, which appear as bright stars moving in the sky. Stargazers can see up to six satellites within an hour of observing the planets.
Additionally, astronomers are keeping an eye on a comet, C/2024 G3 (ATLAS), which recently survived an encounter with the sun. The comet’s visibility will depend on its trajectory and brightness, but enthusiasts may spot it around January 18.
Dr. Allen recommends using a basic sky map or downloading a phone app to help locate the planets in the night sky. With clear skies and binoculars, viewers can enjoy this rare “planet parade” during school holidays, offering an unforgettable experience for families and stargazers alike.
