This picture is a composite of 31 different images, taken in the shadow of the solar eclipse that passed over Asia and parts of the Pacific back in July for 6 minutes and 39 seconds. That’s the longest solar eclipse anyone on Earth will witness this century; a longer one isn’t coming until 2132.
The photo shows the solar corona that make up the sun’s “atmosphere” in glorious detail. It's whorls and loops extend millions of miles into space, are nearly 200 times hotter than the visible surface of the sun, and yet aren’t nearly as bright (by a factor of something like a million), hence, we can only see them during eclipses.
