If you're in the path of totality for the April 8 total solar eclipse, you'll experience a brief period of darkness — totality — for a few seconds or minutes. This is the only safe time to look directly at the sun without solar eclipse glasses. If you observe the sun's corona during totality, you may see dark-pink towers and loops of electrically charged plasma stretching many times the diameter of Earth into space. During the last total solar eclipse, in Australia on April 20, 2023, these "prominences" were spectacular — and vast.
These prominences will almost certainly be on show during totality in North America on April 8, because the sun is likely at the peak of its 11-year solar cycle, known as solar maximum.
