Solar Eclipses Quiz over Nova Video Shortened Version (25)

What can astronomers now predict about eclipses with more accuracy?

• The exact duration of the eclipse

• The precise path of the eclipse to the nearest hundred feet and time to the nearest tenth of a second

• The number of eclipses that will occur in a year

• The exact size of the moon's shadow on Earth

What is the purpose of deploying citizen scientists or community participants during the April 2024 total eclipse?

• To help with setting up telescopes for professional astronomers

• To observe the eclipse shadow passing over each location and gather observations into a one-hour long movie

• To provide security during the eclipse event

• To distribute eclipse glasses to the public

What was the significant discovery made by a team of astronomers studying the corona during an eclipse in the late 1800s?

• They found that the corona changes shape during an eclipse

• They discovered a new planet

• They observed solar flares for the first time

• They made a surprising discovery about the corona

What did the astronomer Young discover when he pointed a spectroscope at the corona during an eclipse?

• He discovered a new element called "Coronium."

• He found that the corona contained no known elements.

• He observed a mysterious spectral line never seen before.

• He confirmed the presence of iron in the corona.

Why is the corona's temperature a problem for scientists?

• It is cooler than the surface of the sun.

• It is the same temperature as the surface of the sun.

• It is hotter than the surface of the sun.

• It has a variable temperature that changes during an eclipse.

What was the purpose of Amir Caspi and his team flying two NASA jet aircraft fitted with telescopes above the clouds?

• To discover new elements in the corona.

• To extend viewing time and avoid clouds during an eclipse.

• To measure the exact temperature of the corona.

• To prove that the corona is made of iron.

What advantage did flying above 90 percent of the atmosphere provide to the scientists studying the corona?

• They could see the corona without the need for telescopes.

• They could access wavelengths not normally visible from the ground.

• They could directly sample the material in the corona.

• They could confirm the presence of "Coronium."

How fast were the jets traveling to keep up with the eclipse shadow, according to the narrator?

• 1,500 miles an hour

• 500 miles an hour

• 2,000 miles an hour

• 3,000 miles an hour

What is the temperature range of the solar chromosphere?

• 10 to 20,000 degrees Celsius

• 1 to 10,000 degrees Celsius

• 100 to 50,000 degrees Celsius

• 20 to 30,000 degrees Celsius

What did the infrared images collected by Amir and his team in 2017 show?

• Prominences and active regions have different temperatures

• Prominences and active regions have the same temperature

• Prominences and active regions do not glow

• Prominences and active regions are not important for the corona's magnetic field
