Rare celestial alignment offers a chance to observe the Red Planet at its most brilliant

On 16 January, Singapore residents will have the rare opportunity to see Mars at its brightest and closest for the year, weather conditions permitting. The Red Planet will be in “opposition,” a celestial event where Earth aligns directly between Mars and the Sun, providing optimal viewing conditions.

What Happens During Mars Opposition?
Mars opposition occurs when the three celestial bodies form a straight line, placing Mars at its nearest point to Earth for the year. Fully illuminated by the Sun, the planet appears larger, brighter, and distinctly red in the night sky, making it a prime time for observation.

When and Where to Watch?
Mars will begin its ascent around 7:30 PM on 16 January, reaching an optimal height for viewing by 8:30 PM, according to the Observatory at Science Centre Singapore. The planet will peak at its highest point in the sky around 1:00 AM on 17 January.

Clear skies are essential for viewing, and open areas like Marina Barrage, East Coast Park, and Southern Ridges are ideal spots to catch the planet unobstructed. Mars will be visible to the naked eye as a reddish “star,” though a telescope will reveal finer details such as its polar caps and surface features.

However, the Meteorological Service Singapore forecasts thundery showers on 16 January afternoon, which could hinder visibility. For enthusiasts, Mars may also be observed during the Science Centre’s Stargazing and Digital Planetarium event on 17 January, held at the Omni Theatre.

A Rare Opportunity
Mars oppositions occur approximately every two years due to the varying orbital periods of Earth and Mars. After this event, the next opportunities to witness Mars at opposition will be on 19 February 2027 and 25 March 2029. The last occurrence took place on 8 December 2022.

This celestial event offers an extraordinary chance to marvel at the Red Planet, making it a highlight for astronomy enthusiasts in Singapore.
