The Sun
From Yohkoh And From Nso (Comparison)

These images of the Sun were taken from two sources, the joint ISAS/NASA spacecraft Yohkoh and the National Solar Observatory at Sacramento Peak in Sunspot, New Mexico. The images from Yohkoh are all in soft x-rays and the ones from NSO are the K emission line from Ca II. They are shown side-by-side for images taken the same day (but not necessarily the same time) for comparison. These are only selected images from the selected days and are only intended to be representative images.
