The final full moon of 2025 treated stargazers to a high-flying lunar spectacle as the "Cold Moon" glowed among the stars of the constellation Taurus on Dec. 4.
December's full moon was the third in a string of "Supermoons" — full moons that occur when the moon reaches its closest point to Earth in its monthly orbit. Around this time, it can appear up to 14% larger and 30% brighter than the smallest moon of the year, sometimes known as a "micromoon".
