  • A total solar eclipse will take place in North America on April 8.
  • 2
  • Millions of people will be able to fully experience the event, which is expected to darken the sky for more than four minutes.
  • 3
  • A total solar eclipse happens when the sun, moon and Earth perfectly line up.
  • 4
  • This results in sunlight being blocked.
  • 5
  • The quality of the observations will depend on weather and the position where people watch the eclipse from.
  • 6
  • The path of totality - meaning places where people will see a total blockage of the sun - will stretch across areas of Mexico, the United States and Canada.
  • 7
  • People in North America who are outside of this path will still be able to see a partial eclipse.
  • 8
  • The American space agency NASA says the eclipse will begin over the South Pacific and reach Mexico's Pacific coast at around 11:07 a.m. Pacific Time.
  • 9
  • It will then enter the United States in Texas.
  • 10
  • The path of totality will then pass through a series of states before heading out from the northernmost state of Maine.
  • 11
  • The eclipse will enter Canada in Ontario and move across the nation before leaving northeastern Canada into the Atlantic.
  • 12
  • An estimated 44 million people live inside the 185-kilometer-wide path of totality, with about 32 million in the U.S.
  • 13
  • The eclipse is expected to last four minutes and 28 seconds, about twice as long as the one that darkened skies in 2017.
  • 14
  • The U.S. is not set to see another coast-to-coast total solar eclipse until 2045.
  • 15
  • NASA's eclipse watch program is led by Kelly Korreck.
  • 16
  • She told The Associated Press the eclipse will permit many people to experience the "wonder of the universe without going very far."
  • 17
  • People outside the path of totality will still be able to see a partial eclipse.
  • 18
  • The farther these people are from the path, the less the sun will be covered.
  • 19
  • For example, experts say Americans farthest from this path - such as in the northwestern cities of Seattle and Portland - will see about one-third of the sun blocked.
  • 20
  • As was the case with past eclipse events, people are being warned about the dangers of looking directly at the sun during the event.
  • 21
  • Since normal sunglasses are not considered effective protection, special eclipse glasses are suggested for eclipse watchers.
  • 22
  • The glasses should only be removed during moments when the sun's face is covered during complete totality.
  • 23
  • A total solar eclipse develops in several different parts, or stages.
  • 24
  • The event starts with a partial eclipse as the moon begins to pass between Earth and the sun.
  • 25
  • During this stage, a partial blockage leaves the sun looking a bit like a banana.
  • 26
  • During the next stage, called Baily's Beads, points of light from the sun shine around the moon's edges.
  • 27
  • This effect is produced by the moon's differing landscapes.
  • 28
  • NASA notes this stage is quite short and "may not last long enough to be noticeable to all observers of the total solar eclipse."
  • 29
  • In the Diamond Ring stage, a single bright spot appears along the lunar edge even as the sun's atmosphere leaves a ring of light around the moon.
  • 30
  • This effect - which comes right before totality - looks similar to a diamond ring.
  • 31
  • After totality, the other stages then repeat as the moon keeps moving along its path until the end of the eclipse.
  • 32
  • Total solar eclipses generally happen every few years, often in the middle of nowhere like the South Pacific or Antarctic.
  • 33
  • The next total solar eclipse will arrive in 2026. It will be observable along the northern edges of Greenland, Iceland and Spain.
  • 34
  • North America will not experience totality again until 2033, with that one only passing over Alaska.
  • 35
  • It will happen next in 2044, with totality limited to Western Canada and the U.S. states of Montana and North Dakota.
  • 36
  • The next coast-to-coast total solar eclipse in the U.S. is expected to happen in 2045.
  • 37
  • NASA says that one will stretch from Northern California to Cape Canaveral, Florida.
