The European Space Agency post Zooming into the Sun with Solar Orbiter (3/24/2022) says:
One of the images, taken by the Extreme Ultraviolet Imager (EUI) is the highest resolution image of the Sun’s full disc and outer atmosphere, the corona, ever taken.
In total, the final image contains more than 83 million pixels in a 9148 x 9112 pixel grid. For comparison, this image has a resolution that is ten times better than what a 4K TV screen can display.
Ok, no data here and I don’t have any ideas on how to connect this to a math class, but if you go to the article you will be treated with a zoomable image of the sun (way more detail than the one copied here). I’m posting this because it is so cool. The article itself provides some tips on what to look at:
At the 2 o’clock (near the image of the Earth for scale) and 8 o’clock positions on the edges of the Sun, dark filaments can be seen projecting away from the surface. These ‘prominences’ are prone to erupt, throwing huge quantities of coronal gas into space and creating ‘space weather’ storms.
Enjoy.
