Sequence begins with a backyard view of the Scorpius region, then zooms to the Hubble Space Telescope’s Wide Field Planetary Camera view of the M4 globular star cluster, located in the Milky Way Galaxy’s stellar halo. Circles fade in, indicating the location of the cooling white dwarf stars astronomers used to determine the age of the Universe. Credit: NASA and B. Preston (STScI and Max-Q Digital)
