Tonight the Moon will exhibit a waxing crescent phase with about 23% of the lunar disk illuminated. With binoculars, you will see four large dark patches close together. These are large basaltic plains that formed because of ancient volcanic eruptions. The lava that erupted to the lunar surface forming the maria, settled in large impact basins that are the scars that formed during the Late Heavy Bombardment period of our solar system.
