Questions & Answers

Q: What is the difference between an annular and a total solar eclipse?

In an annular solar eclipse, the moon is further away from the Earth, resulting in the moon not completely blocking out the sun and leaving a "Ring of Fire" in the sky. In a total solar eclipse, the moon is closer to the Earth, completely blocking the sun, allowing us to see the solar corona.

Q: How can we safely view the solar eclipse?

During totality, it is safe to look directly at the sun without any protection. However, before and after totality, eclipse glasses or proper solar filters should be used to protect eyes from harmful radiation. Indirect viewing methods, such as pinhole projectors, can also be used.

Q: What science experiments will be conducted during the eclipse?

NASA will be conducting various experiments, including using the WB 57 high altitude research jet to study the solar corona and dust around the sun. Other experiments will focus on measuring changes in the upper atmosphere and studying radio waves coming from the sun.

Q: Will the eclipse affect the International Space Station?

The International Space Station will not be affected by the eclipse. Astronauts on the space station will be able to view the moon's shadow moving across the Earth's surface, providing a unique perspective.

Summary & Key Takeaways

  • The total solar eclipse will cross Mexico, the United States, and Canada, offering a unique chance for millions to witness the moon completely blocking the sun.

  • This will be the last total solar eclipse to cross the contiguous United States for the next 20 years.

  • An estimated 31.6 million people live within the path of totality, making this a special event for a large number of individuals.
