A solar eclipse occurs when the moon comes between the earth and the sun, and the moon casts its shadow on the earth. During totality the sun’s corona becomes visible as a white halo around the black disk of the sun. The sky darkens, but the entire horizon is lit with sunset colors.
In this photograph the horizon appears to curve upwards due to the distortion of the fisheye lens. The bright planet Venus is visible, and Jupiter and Mercury can be faintly seen between Venus and the sun.
