Astronomical Events

The astronomical calendar is full of recurring spectacles, each driven by the predictable motions of the Earth, Moon, Sun, and planets. Knowing what causes each event — and when it peaks — is the key to catching it at its best.

Eclipses

A solar eclipse occurs when the Moon passes between the Earth and the Sun, casting its shadow on our planet; a total solar eclipse briefly turns day into twilight along a narrow path. A lunar eclipse happens when the Earth slips between the Sun and a full Moon, tinting the lunar disk a deep coppery red — the so-called "blood moon." Unlike solar eclipses, lunar eclipses are safe to view with the naked eye and visible from an entire hemisphere at once.

Meteor Showers

Meteor showers occur when Earth plows through the debris trail left behind by a comet or asteroid. Tiny grains burn up in the atmosphere as "shooting stars" that appear to radiate from a single point in the sky. Major showers like the Perseids (August) and Geminids (December) can produce dozens of meteors per hour under dark skies, peaking on predictable dates each year.

Supermoons and Conjunctions

A supermoon is a full Moon that coincides with perigee — the point in its slightly elliptical orbit closest to Earth — making it appear marginally larger and brighter than usual. A conjunction is a close apparent pairing of two or more bright objects, such as two planets or a planet and the Moon, gathered within a small patch of sky. These events need no equipment and are among the easiest to observe from anywhere.
