What is a Total Solar Eclipse?
According to the Adler Planetarium, a solar eclipse can only occur at the New Moon Phase, when the arrangement in space is a line between the Sun, Moon, and Earth.
The moon, directly between the sun and Earth, casts a shadow on the planet, darkening the daytime sky. Those in the dark part of the moon’s shadow (the umbra) will experience a total eclipse, while those in the light part (the penumbra) will see a partial eclipse.
What Does "The Path of Totality" Mean?
The period of totality refers to the time during a total eclipse when the moon completely obscures the sun. The period of totality is usually brief, lasting just a few minutes. Astronomy.com says the maximum period of totality for the April 8, 2024, solar eclipse is four minutes and 28 seconds.
The longest period of totality for the 2017 solar eclipse was quite a bit shorter, just about two minutes and 40 seconds, according to NASA.
