Australia will be able to see a blue supermoon on Monday evening.
A supermoon happens a few times a year when the moon reaches its closest point to Earth in its orbit, making it appear bigger and brighter.
Blue moons are rarer – occurring once every two or three years – when we see two full moons in a calendar month.
Full moons happen roughly every 29 days when the Sun’s light hits the side of the moon closest to Earth. A blue supermoon is when both of these phenomena happen at the same time.

The moon will appear at its biggest and brightest on Tuesday, around 4:30am (AEST). This is when the moon’s orbit will reach its closest to Earth.
NASA says this will also be a good viewing time for Saturn as it nears its “closest and brightest night” which is in early September. With a telescope, Titan (Saturn’s largest moon) will be visible alongside Saturn’s rings.
According to NASA, the blue supermoon will be visible in Australia until Wednesday evening. The next blue supermoon will be in May 2026.
