Este fin de semana, el cielo nocturno será el escenario de un espectáculo astronómico poco común y muy esperado: la Blue Moon of 2026. This special event, visible in various parts of the world, including Argentina, will be a unique opportunity for cosmos enthusiasts.
Blue Moon and Micromoon: A Unique Astronomical Phenomenon
The term Blue Moon can be misleading as it does not mean the Moon turns a bluish hue. In reality, it refers to the second full moon in the same astronomical season, a phenomenon that occurs approximately every two or three years.
The upcoming event will not only be a Blue Moon, but it will also coincide with a micromoon. This occurs when the Moon is at its farthest point from the Earth, known as apogee, making it appear up to 14% smaller and 30% less bright compared to a supermoon.
For astronomy enthusiasts, the combination of these two phenomena is particularly exciting and rare.
The Blue Moon will reach its fullest during the night of Saturday, May 30, and the early morning of Sunday, May 31. In Argentina, the best time to observe it will be between 6:30 PM and 10 PM, when the Moon rises high enough to offer a clear view.
This celestial spectacle will be visible to the naked eye throughout the country, weather permitting. Although no special equipment is needed, binoculars can enhance the experience by revealing additional details of the lunar surface.
To make the most of the Blue Moon, experts suggest seeking locations with low light pollution, such as rural areas or open spaces away from city lights. Looking east during the moonrise can offer a more striking image.
The rarity of this event lies in a Blue Moon coinciding with a micromoon, something that does not happen every year and makes this event one of the main astronomical highlights of 2026.
Unlike other celestial phenomena that require specific conditions or sophisticated equipment, this Blue Moon is accessible to everyone, fostering interest in astronomical observation and providing one of the most memorable images of the year.
