Ver en NASA ↗Why are eclipses rare? The moon's orbit is tilted. Sometimes the moon's shadow is too high above the Earth. Sometimes it is too low. Other times, it is just right.
Ver en NASA ↗On Sept. 13, 2015, as NASA’s Solar Dynamics Observatory, or SDO, kept up its constant watch on the sun, its view was photobombed not once, but twice. Just as the moon came into SDO’s field of view on a path to cross the sun, Earth entered the picture, blockin…
