May 2026 Blue Moon and Moon‑Spica Conjunction Highlight Astronomy

A second full moon in the same calendar month will occur on 31 May 2026, known as a Blue Moon. It will reach full phase at 9° Sagittarius, closing a six‑month lunar cycle that began with a new moon in the same sign on 20 November 2025. Astrological commentary notes that this lunation emphasizes the Gemini‑Sagittarius axis, with Sagittarius, Gemini, Virgo and Pisces described as the four signs most affected. The chart also shows Mars in Taurus square Pluto in Aquarius and Venus in Cancer square Saturn in Aries, indicating potential tension in social issues and personal relationships.

Separately, from the night of 30 April to 1 May 2026 the Moon will appear very close to Spica, the brightest star of the Virgo constellation. In Spain the conjunction will be visible shortly after sunset, with the Moon rising in the southeast and both bodies staying within a few degrees of each other for several hours. The event coincides with the May full moon, traditionally called the “Luna de las Flores,” and offers a striking visual contrast between the bright lunar disc and the blue‑white hue of Spica.
