Sixth of the Sunday on Our World. Look up to the night sky and share Carl Sagan's fascination with the stars. The number of stars we can see is only the tiniest fraction of the number of stars that are. From the way the first astronomers saw the constellations, to how they are seen today by different cultures. The mystery, the beauty of the cosmos. What wonders are waiting for us on the planets of the nearby stars? Sixth of the Sunday on Minds Our World.
