Why are the loops in the sun’s atmosphere so neat and tidy?
Observations during the total solar eclipse may explain why the sun’s atmosphere is so organized despite arising from a tangled magnetic field.
- Astronomy
What can the eclipse tell us about the corona’s magnetic field?
The corona’s plasma jumps and dances thanks to the magnetic field, but scientists have never measured the field directly.

Can the eclipse tell us if Einstein was right about general relativity?
During the eclipse, astronomers will reproduce the 1919 experiment that confirmed Einstein’s general theory of relativity.

What can we learn about Mercury’s surface during the eclipse?
Instruments aboard twin research jets will take advantage of the total solar eclipse to make the first thermal map of Mercury.

What happens in Earth’s atmosphere during an eclipse?
The charged layer of Earth’s atmosphere gets uncharged during an eclipse, and that could have implications for everything from GPS accuracy to earthquake prediction.

What do plants and animals do during an eclipse?
A citizen science experiment will gather the biggest dataset to date of animal responses to a total eclipse.

What will scientists learn from the Great American Eclipse?
Between now and August 21, astronomy writer Lisa Grossman will explore the top questions scientists will tackle during the 2017 total solar eclipse.

Why is this year’s solar eclipse such a big deal for scientists?
Total eclipses offer scientists a way to see all the way down to the sun’s surface.
