The European Space Agency’s Solar Orbiter recently took 25 images of the Sun from a distance of 46 million miles that, when stitched all together, form the highest resolution photo of the Sun (and its corona) ever created.
The high-resolution telescope of EUI takes pictures of such high spatial resolution that, at that close distance, a mosaic of 25 individual images is needed to cover the entire Sun. Taken one after the other, the full image was captured over a period of more than four hours because each tile takes about 10 minutes, including the time for the spacecraft to point from one segment to the next.
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.
You can zoom in on the image here to see how remarkably detailed it is.
