Solar eclipse
The Moon passes between the Earth and the Sun, hiding all or part of the solar disk for observers on Earth.
Discover the 7 main types of eclipses — solar and lunar — with simple explanations, clear diagrams and safe-observation advice.
Sun – Moon – Earth alignment
It all starts with an alignment between the Sun, the Earth and the Moon.
The Moon passes between the Earth and the Sun, hiding all or part of the solar disk for observers on Earth.
The Earth passes between the Sun and the Moon. The Moon then enters the shadow cast by the Earth.
Four different configurations depending on the Moon's apparent size and the alignment.
The Moon completely blocks the Sun's disk. The sky darkens and the solar corona becomes visible.
The Moon passes in front of the Sun but appears slightly smaller, leaving a bright ring visible around it.
The Moon only covers part of the Sun, which then appears as a crescent.
Depending on the observation location, it can appear total or annular.
Important: during any partial or annular solar eclipse, it is never safe to look at the Sun without proper protection.
Lunar eclipses can be observed with the naked eye, without any protection.
The Moon enters fully into the Earth's shadow and may appear red-orange.
Only part of the Moon passes through the Earth's shadow.
The Moon only crosses the Earth's penumbra, causing a slight and subtle darkening.
Your glasses stay useful for years to come: more than twenty solar eclipses are expected in the next decade.
