This nebula was mostly hydrogen and helium until gas streamed in from a nearby exploding star. During the supernova event that marks the demise of a star much more massive than the Sun, elements much more massive than helium are created and dispersed into space. ) The turbulence created by the interacting gas caused the nebula to develop “clumps,” or condensations. Large clumps became protostars—objects that would ultimately evolve into energy-generating stars. Smaller clumps became the protoplanets.

During the late 1960s and early 1970s, nine Apollo craft carrying three men each orbited or flew by the Moon. Lunar modules carrying two men each separated from the main craft and landed on the Moon during the flights of Apollo 11, 12, 14, 15, 16, and 17. One result of these explorations was a fresh appreciation of the Earth as a life-bearing world. Another was an understanding of the Moon’s nature and origin. We now know that our Moon is a geologically dead world without the crustal movements, volcanism, and earthquakes that characterize our home planet’s dynamic geology.

There are two high tides and two low tides each day. This picture is greatly simplified because no provision is made for the effects of land or the Sun’s attraction, which complicates the tidal picture. The greatest range between high and low tides occurs at full and new Moons, when the Moon and the Sun pull in approximately the same direction. As well as oceanic tides, the Moon and the Sun produce tidal variations in Earth’s atmosphere. At high tide, the Earth’s atmosphere extends a little farther above the surface than at low tide.
