 The image shows the six phases of a solar eclipse. The phases, from left to right, are:

1. First contact: The Moon begins to move in front of the Sun.
2. Partial eclipse: The Moon covers part of the Sun.
3. Annular eclipse: The Moon covers the entire Sun, but a ring of sunlight is still visible around the Moon.
4. Total eclipse: The Moon completely covers the Sun, and the sky darkens.
5. Partial eclipse: The Moon begins to move away from the Sun, and the Sun's light begins to reappear.
6. Last contact: The Moon moves completely away from the Sun, and the eclipse is over.
