Image: Nearly 200,000 light-years from Earth, the Large Magellanic Cloud, a satellite galaxy of the Milky Way, floats in space, in a long and slow dance around our galaxy. Vast clouds of gas within it slowly collapse to form new stars. In turn, these light up the gas clouds in a riot of colors, visible in this image from the NASA/ESA Hubble Space Telescope.

; in re: The Moon; Chang’e 5. Large Moon mares:
volcanic pits. Measure parallax of nearby stars: if you look in August and January, it’ll shift slightly. Can get precise location, but not as well from the ground; rather e, from Gaea – 1.8 billion stars ! Can map the Milky Way. Some stars move slowly toward the elliptic; others flying away fast. 100 parsecs. Large Magellanic Cloud.
