Eclipses show wrong physics can give right results
Math for making astronomical predictions doesn’t necessarily reflect physical reality.

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.
- Astronomy
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.

Moon had a magnetic field for at least a billion years longer than thought
The moon’s magnetic field could have lasted until about a billion years ago.

Nostalgic Voyager documentary relives first exploration of the solar system
A new TV documentary is a tender tribute to Voyagers 1 and 2, which launched 40 years ago and were the first spacecraft to visit the outer solar system.

The solar system’s earliest asteroids may have all been massive
A team of astronomers says the original asteroids all came in one size: extra large.
