Blood moon lunar tides9/27/2023 The Aurignacian Lunar calendar provided the basis for early calendars. depicting the lunar cycle have been found, indicating that the Aurignacian culture, located in Europe and Southeast Asian, charted the Moon phases, most likely to track animal migration for hunting. It takes 27.3 days for the full orbit around the Earth, but due to the way sunlight hits the Moon, it actually takes 29.5 days from one new Moon to the next.Īs a result, the Moon has long been used by man to measure time. There are eight lunar phases from the invisible new Moon (because the side facing the Earth is dark) through to the bright full Moon. We always see the same side of the Moon because it rotates at the same rate that it revolves around the Earth. It has almost no atmosphere and only one-sixth of Earth’s gravity, but as the Moon and Earth exert a gravitational pull on each other, this affects Earth’s tides causing bulges in the sea on the sides closest and farthest from the Moon, thus creating our daily high and low tides. It has traces of ice and water, but its surface is dust and rock debris marked with craters caused by collisions with comets, meteoroids and asteroids. NASA (US National Aeronautics and Space Administration) has registered 290 moons in our solar system with Earth having just one in comparison to Saturn’s 146!ĭisappointingly, the Moon is not made of cheese! Its core is iron and the crust is made of magnesium, oxygen and silicon. So, what exactly is the Moon and how did it come about? One theory is that 4.5 billion years ago, the Earth crashed into another mass and the debris that subsequently orbited the Earth became the Moon, orbiting at around 3,700 kms an hour some 384,000 kms away. For example, over half the people in the UK are denied this beautiful sight. Sadly, due to light pollution in parts of the world, the starry sky is not visible. Occurring between July 17 and August 24, they peak this year on August 13, so make sure you look up at night to see up to 100 meteors an hour. Each year we watch the Perseids meteor showers, which are made up of space debris from the comet Swift-Tuttle. There is little light pollution where we live, so it is amazing to see the Moon and thousands of stars. However, it also celebrates the Moon missions and its future exploration, with July 20 chosen as this marks the anniversary of Apollo 11’s Moon landing. July 20 is National Moon Day, created in 2021 by the United Nations General Assembly not to celebrate what was probably the 20 th century’s greatest achievement – man walking on the Moon – but for “international cooperation in the peaceful uses of outer space”.
