The Milky Way\u2019s elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars. Spanning more than 100,000 light-years, Earth is located along one of the galaxy\u2019s spiral arms, about halfway from the center. Credit: NASA

ALT A close-up view of the Moon, filling most of the frame. Along the left side of the image, the terminator divides the illuminated and darkened sides of the Moon. Just before the terminator, the lunar surface transitions from the smoother near side to the bumpier, more cratered far side. From this perspective, the distinction between the two is clearer. The craters on the far side create a bumpy, textured surface. Near the lower right hand corner of the image, a large circular basin has darker mottling near its center. Credit: NASA

Two white solid rocket boosters are on either side of the orange core stage. White plumes emit from the rocket engines. The sky is blue in the background. Credit: NASA/Michael DeMocker
