Eclipses

Solar and lunar eclipses explained — the types, the geometry, and how to watch them safely. Specific eclipse dates and paths are prepared for published NASA predictions; none are fabricated.

Night SkyReference data

Solar eclipses

A solar eclipse happens at New Moon, when the Moon passes between Earth and the Sun. Solar eclipses in detail →

Total Solar Eclipse
The Moon completely covers the Sun's disc along a narrow path of totality, revealing the corona. Only safe to view with the naked eye during the brief total phase.
Annular Solar Eclipse
The Moon is near apogee and too small to cover the Sun, leaving a bright 'ring of fire'. Never safe to view without a solar filter.
Partial Solar Eclipse
The Moon covers only part of the Sun. Requires certified solar filters throughout.
Hybrid Solar Eclipse
A rare eclipse that shifts between annular and total along its path.

Lunar eclipses

A lunar eclipse happens at Full Moon, when the Moon passes through Earth's shadow. Lunar eclipses in detail →

Total Lunar Eclipse
The Moon passes fully into Earth's umbral shadow and often turns coppery red (a 'blood Moon'). Completely safe to watch with the naked eye.
Partial Lunar Eclipse
Only part of the Moon enters Earth's umbra, leaving a dark bite on the lunar disc.
Penumbral Lunar Eclipse
The Moon passes through Earth's faint outer shadow, producing only a subtle shading.
