Apollo 12 astronauts took this dramatic photograph of the Sun emerging from behind the Earth. From this distant perspective, part of the solar disk peers over the Earth's limb, its direct light producing the jewel like glint while sunlight scattered by the atmosphere creates the thin bright crescent. Today at 10:24 pm Eastern Daylight Time is the Summer Solstice. From an earthbound perspective, the solar disk will climb to its greatest northern declination marking the Northern Hemisphere's first day of Summer and creating the longest day -- with over 15 hours of daylight near latitude +40 degrees.
