Lunar eclipses

Apollo 13, also known as (AS-508), was suppose to be the third mission to land on the moon. The crew on the spacecraft consisted of Fred W. Haise, Jr., lunar Module Pilot, John J. Swigert, Jr., command module pilot, and James A. Lovell, Jr., commander. Launched at 2:13 p.m. on April 11, 1970 from the launched from complex 39A at Kennedy Space Center. The Apollo 13 mission was planned to launched and land on the moon and return back to Earth. Unfortunately, after about 56 hours into their…

There are many theories behind why Stonehenge was built, but a main component is the application that it has to astronomy. One of the theories believes that Stonehenge is an astronomical calculator or calendar. One thing is however evident, it was no accident; every stone was placed strategically and purposefully. No one is completely certain who built Stonehenge, but it was erected in Wiltshire, England approximately 4,500 years ago. It is carefully aligned so that, if one sits at the…

We all experience day and night and every night when the sun goes down, we have a different form of light. The moon orbits the Earth, like the Earth orbits the sun. The moon we see only orbits around Earth. As the moon orbits our planet, we see that the shape of the moon changes throughout each month. This is because the amount of light that the sun that illuminates the moon changes monthly. These are called the phases of the moon. The phases of the moon are the changes in amount of moon…

Although the constellations are now used more as celestial landmarks than anything else, that wasn’t always the case. For much of human existence, the stars represented something much more spiritual. For example, many of the names for the constellations we recognize today were derived from the Ancient Greeks (http://centralastronomyclass.pbworks.com/w/page/15400605/Constellations%20of%20Different%20Cultures (Links to an external site.)Links to an external site.). But they were only…

these changes are called lunar phases. There are 8 lunar phases, it starts with new moon that waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent. Those are the 8 lunar phases and they all happen at least once in every month. An eclipse is an event when one object in space casts a shadow onto another, There are two types of eclipses. A lunar eclipse is when the moon moves through earth's shadow. A solar eclipse is when the moon is in…

1. How is the Moon dependent on the Sun? The Moon is dependent on the Sun for its different lunar phases. Although these phases may not be essential to the existence of the Moon, they would not occur without the Sun. Neither a lunar nor a solar eclipses would be possible without the Sun, again. Also, although this is not a direct dependence upon the Sun, if the Sun did not give the Earth an object to orbit, the Moon may never have fallen into orbit with the Earth. 2. How are seasons created?…

Monday marks Columbus Day for people in the United States, but did you know there was a lunar twist to the famous explorer's journey? On Oct. 12, 1492, Columbus came ashore on an island northeast of Cuba, which he later named San Salvador (Holy Savior). Over the next 10 years Columbus would make three more voyages to the "New World." On his fourth and final voyage, while exploring the coast of Central America, Columbus found himself in dire straits. He left Cádiz, Spain, on May 11, 1502, with…

the morning sky. Synchronous rotation occurs when tidal forces drag the rotation of a smaller body, until it matches the period of revolution around the larger body. A sidereal month is the amount of time it takes for the Moon to complete a full Lunar Cycle(27.3 days). A Synodic month is the amount of time it takes for the Moon to realign with the Sun(29.5 days). The sun and moon cause tides, although the moon has a much larger effect. The tides are larger when the moon and sun are opposite,…

NASA has recently discovered a new planet Yelger in the Andromeda Galaxy. It is the right distance from the sun to support life. It is the same size and mass as Earth. It takes 700 Earth days to revolve around the sun(360 on Earth), and takes 20 Earth hours to rotate around its axis(24 on Earth). It’s temperatures are about the same as on Earth, and has a tilt of 45º. It’s moon is the same distance away from Earth but it twice the mass and size. Because Yelger takes 20 hours to rotate on it’s…

Thales is believed to have anticipated the eclipse of the Sun on the 28th of May B.C. While it is unknown how Thales got to his conclusion of solstices, he was mentioned to be the first to have determined the course of the Sun from solstice to solstice. Presumably with the exploration of solstices…
