Eclissi totale di Sole, 8 aprile 2024

An extraordinary event visible from Mexico, the United States and Canada, the only “black sun” of the year.

The much-anticipated total solar eclipse of 8 April 2024 began at 12:39 local time on the Cook Islands in the Pacific Ocean and partially started on the coast of Mexico near the city of Mazatlan, where thousands of people gathered.

The total eclipse of the sun

More than four minutes of total darkness were experienced in Texas, starting at 14:40 (20:40 in Italy), plunging the landscape into a darkness akin to night. Temperatures in the area dropped dramatically. In a matter of minutes, the area went from oppressive humidity to cold.

The perfect alignment of the Earth, Moon and Sun caused the lunar disc to completely obscure the Sun’s photosphere (the region where the vast majority of solar radiation originates). This allowed us to observe the Sun’s corona, the outermost part of its atmosphere, with the naked eye. In the following images it appears as a whitish halo around the darkened disc.

Against a dark background, the Moon slowly moves in front of the orange Sun. The Sun appears smaller until it’s a thin crescent. A bright flash of light appears, then white streams of light fill the image around a dark circle. The Moon then slowly moves off the Sun again. Photo: © NASA
