What are the Phases of the Moon?

What are the Phases of the Moon?

New Moon

The side of the moon facing the Earth is not illuminated. Additionally, the moon is up through out the day, and down through out the night. For these reasons we can not see the moon during this phase.

Waxing Crescent

During this phase, part of the Moon is beginning to show. This lunar sliver can be seen each evening for a few minutes just after sunset. We say that the Moon is “waxing” because each night a little bit more is visible for a little bit longer.

First Quarter

During first quarter, ½ of the moon is visible for the first half of the evening, and then goes down, leaving the sky very dark.

Waxing Gibbous

When most of the Moon is visible we say it is a Gibbous Moon. Observers can see all but a little sliver of the moon. During this phase, the Moon remains in the sky most of the night.

Full Moon

When we can observe the entire face of the moon, we call it a Full Moon. A full moon will rise just as the evening begins, and will set about the time morning is ushered in.

Waning Gibbous

Like the Waxing Gibbous Moon, during this phase, we can see all but a sliver of the Moon. The difference is that instead of seeing more of the Moon each night, we begin to see less and less of the Moon each night. This is what the word “waning” means.

Last Quarter

During a Last Quarter Moon, we can see exactly ½ of the Moon’s lighted surface.

Waning Crescent

Finally, during a Waning Crescent Moon, observers on Earth can only see a small sliver of the Moon, and only just before morning. Each night less of the Moon is visible for less time. sources:

@iamascrambledegg Yup! So everytime you look at the moon at night, you’d instantly know the phase of it. :) Last night, I tried to get a glance on it, and I found out that it was on its Waxing Gibbous phase. Did you find out the same thing, too? :)

[diannescientist-blog]

@mrfl-hlgd-25 There’s no specific answer in this question, honestly, but Last Quarter moons come about three weeks after a New moon which comes every 29 ½ days. For some additional information, the latest Last Quarter moon rose in July 26, 2016 :)

I love your blog; it has all the information needed, with simple pictures that summarize everything. I’ve picked up new bits and pieces of information about the moon, thanks to you. Plus, it seems as if you know your topic very well! Keep writing!! :)

@k-leia awww thank youu! ☺️

The Moon lighted up the dark grey sky when the Sun gave up for a lil while and the stars sat there behind.

What is a Moon?

What is a Moon?

                  According to John Carl Villanueva, before the invention of the telescope in the early 1600’s, man just knew the Moon — a round, mysterious astronomical object that people would gaze up to in the night sky. However, as the time progressed,  astronomers discovered that the moon isn’t exactly unique to earthlings, and other planets had their own moons. So exactly what is a moon?

                   A moon (or luna) is the Earth’s only natural satellite. It was formed 4.6 billion years ago around some 30–50 million years after the formation of the solar system. The Moon is in synchronous rotation with Earth meaning the same side is always facing the Earth. The first unmanned mission to the Moon was in 1959 by the Soviet Lunar Program with the first manned landing being Apollo 11 in 1969. It was defined to be a celestial body that makes an orbit around a planet, including the eight major planets, dwarf planets, and minor planets.

                   The first moons to be discovered outside of the Earth’s moon were the Galilean moons of Jupiter, named after astronomer and discoverer Galileo Galilei. The moons Io, Europa, Ganymede, and Callisto are Jupiter’s largest and only the first four to be revealed, as to date, the planet has 63 moons. 

                    Other than the four Galilean moons, Saturn’s Titan and Neptune’s Triton are two other moons which are comparable in size to the Earth’s Moon. In fact, these seven moons are the largest natural satellites in the solar system, measuring more than 3,000 kilometers in diameter. Only the inner planets Mercury and Venus have no moons.

@mrfl-hlgd-25 Oh, this is because the two planets, Mercury and Venus are too close to the sun which makes its orbit quite unstable. Thus, only the remaining planets have a moon. :)) I hope this helped. ;)

Interesting Moon Facts!

Interesting Moon Facts!

The dark side of the moon is a myth. In reality both sides of the Moon see the same amount of sunlight. However, only one face of the Moon is ever seen from Earth. This is because the Moon rotates around on its own axis in exactly the same time it takes to orbit the Earth, meaning the same side is always facing the Earth. The side facing away from Earth has only been seen by the human eye from a spacecraft.

The rise and fall of the tides on Earth is caused by the Moon. There are two bulges in the Earth due to the gravitational pull that the Moon exerts; one on the side facing the Moon, and the other on the opposite side that faces away from the Moon, The bulges move around the oceans as the Earth rotates, causing high and low tides around the globe.

The Moon is drifting away from the Earth. The Moon is moving approximately 3.8 cm away from our planet every year. It is estimated that it will continue to do so for around 50 billion years. By the time that it happens, the Moon will be taking around 47 days to orbit the Earth instead of the current 27.3 days.

A person would weigh much less on the Moon. The Moon has much weaker gravity than Earth, due to its smaller mass, so you would weigh about one sixth (16.5%) of your weight on Earth. This is why the lunar astronauts could leap and bound so high in the air.

The Moon has only been walked on by 12 people; all American males. The first man to set foot on the Moon in 1969 was Neil Armstrong on the Apollo 11 mission, while the last man to walk on the Moon in 1972 was Gene Cernan on the Apollo 17 mission. Since then the Moon has only be visited by unmanned vehicles.

The Moon has no atmosphere. This means that the surface of the Moon is unprotected from cosmic rays, meteorites and solar winds, and has huge temperature variations. The lack of atmosphere means no sound can be heard on the Moon, and the sky always appears black.

The Moon has quakes. These are caused by the gravitational pull of the Earth. Lunar astronauts used seismographs on their visits to the Moon, and found that small moon quakes occurred several kilometres beneath the surface, causing ruptures and cracks. Scientists think the Moon has a molten core, just like Earth.

The first spacecraft to reach the Moon was Luna 1 in 1959. This was a Soviet craft, which was launched from the USSR. It passed within 5995 km of the surface of the Moon before going into orbit around the Sun.

The Moon is the fifth largest natural satellite in the Solar System. At 3,475 km in diameter, the Moon is much smaller than the major moons of Jupiter and Saturn. Earth is about 80 times the volume than the Moon, but both are about the same age. A prevailing theory is that the Moon was once part of the Earth, and was formed from a chunk that broke away due to a huge object colliding with Earth when it was relatively young.

The Moon will be visited by man in the near future. NASA plans to return astronauts to the moon to set up a permanent space station. Mankind may once again walk on the moon in 2019, if all goes according to plan.

During the 1950’s, the USA considered detonating a nuclear bomb on the Moon. The secret project was during the height cold war was known as “A Study of Lunar Research Flights” or “Project A119” and meant as a show of strength at a time they were lagging behind in the space race.

Questions about the Moon :)

Questions about the Moon :)

                 We've already heard about the moon even when we were younger. Our parents often tell us several bedtime stories about it. But what really is the moon made of? Have you ever wondered about how it was formed? How far is it from our living planet, Earth? Years ago, as a young kid, questions have already started dominating a part of our brains. Though, as years passed by, those questions suddenly drowned in just a snap. We started forgetting about those little questions which we've asked ourselves when we were younger. Thus, we stopped searching for answers because we did not start searching for some in the first place. In other words, we forgot about it. :(
