SPLITTIN’ IMAGE The GOES-13 satellite captured this full-disk image of our planet at 7:45 a.m. ET on March 20, just after the 7:02 a.m. ET equinox. The satellite image shows how Earth’s two hemispheres receive equal amounts of sunlight during the equinox; in this image, the sun is artificially created to enhance the picture.
