Word of the day: syzygy
In astronomy, a syzygy (from the Ancient Greek suzugos meaning, “yoked together”) is a straight-line configuration of three celestial bodies in a gravitational system.
The word is often used in reference to the Sun, Earth, and either the Moon or a planet, where the latter is in conjunction or opposition.
Such a configuration explains why this evening we will experience a phenomenon known as a “super moon” when the moon will be the closest to Earth since 1948 (the year of my birth). More information here.
