Lunar phase (or Moon phase) refers to the appearance of the illuminated portion of the Moon as seen by an observer, usually on Earth. The lunar phases vary cyclically as the Moon orbits the Earth, according to the changing relative positions of the Earth, Moon, and Sun. One half of the lunar

The Milky Way is the galaxy that contains our Solar System. The descriptive "milky" is derived from the appearance from Earth of the galaxy a band of light seen in the night. From Earth, the Milky Way appears as a band because its disk shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis and an observation by Edwin Hubble showed that the Milky Way is just one of many galaxies.

Model 1: “Moon phases are caused by the shadow of the Earth on the Moon”

Buckle your seatbelts, because in three shorts pages, I am going to teach you, something I learned a few days ago. So sit down, and enjoy the experience. Usually during the night the most noticeable thing in the sky is the moon and its brightness. However, the moon does not actually make any light of its own or ever change shape. The moon appears like that because it reflects light from the sun. The moon appears to be lighter or darker at different times of the month because of the positions of the moon, sun, and Earth. The moon revolves around the Earth. As the moon orbits it reflects different amounts of light due to the angle at which it receives sunlight. Which cause the lunar cycle. The cycle is made up of different stages which are new

This is caused as the moon orbits around earth. It takes the moon approximately 29.5days to travel around earth. Therefore we are limited to how much of the moon we can see. The moon gets its source of light from the sun but not directly. It does it get sunlight from the reflections of earths. Without the sun we would never be able to see the moon. As the moon is orbiting the angles will change causing the phases of the moon. Example: for a new moon half of the moon receives light but only half and that half is not visible from earth as it’s facing the opposite direction from earth(facing the sun). Another example would be a quarter moon. Half of the moon is still receiving sunlight except a quarter is visible from earth as the other quarter is facing the sun making it only a quarter moon not a full moon. Do the certain phases of the moon come at certain times during the orbiting

How does the moon change it phases? Moon phases is where the moon can change into different phases. “The moon doesn’t produce its own light, Instead it reflects light from the sun,” said a moon article. The moon change it phases by it’s between the earth, and the sun. The moon help us by providing light to our planet, but the sun help the moon glow to shine light in our planet. Do you ever wonder how old is the moon? If you don’t know I will tell you right now the moon is 4.53 billion years. All the name of the moon phases are last quarter, waning crescent, new moon, waxing crescent, first quarter, waxing gibbous, full moon, and waning gibbous they

The moon is the planet Earth’s only natural satellite and is one of the largest in the Solar System. This natural satellite was not formed long after Earth about 4.5 billion years ago. The gravitational forces continue to keep the moon in orbit of Earth. Even though it appears so, the moon does not physically produce light but it does reflect light from the sun (which is why we are able to see it). It takes our Moon 27.3 days to completely cycle through the Lunar month, which has eight phases. Through these different phases we see it lit from different angles and this depends upon the position of the Moon in its orbit. These phases include; the new moon, waning crescent, third quarter, waning gibbous, full moon, waxing gibbous, first quarter, waxing crescent and this process repeats.

The Milky Way is a galaxy. The Milky Way measure 100,000–120,000 light-years in diameter, it is home to planet Earth and the other planets that we all know. The Milky Way is warped. the Milky Way is a disk about 120,000 light years across with a central bulge which has a diameter of 12,000 light years. The Milky Way has over 200 billion stars. It also has enough gas and dust to make billions more. The Milky way galaxy was made from other galaxies by eating them and that's how they got there shape. We all have seen pictures of the Milky Way but they are either pictures of another galaxy or a talented artist. The Milky Way has a supermassive black hole at the center. The center of our galaxy is called Sagittarius A, it's a massive source

First is the New moon, the waxing crescent moon, first quarter, waxing gibbous, the full moon, waning gibbous, the third quarter, and last the waning crescent. The Moon takes about 4 weeks go orbit around earth. 27.3 days to be specific. During the new Moon, the Moon is aligned with the Earth and Sun. We see the side of the Moon that is not bright by the Sun. As the Moon moves eastward aside from the Sun, we see a little bit more of the Moon’s bright side each night. A couple of days after the New Moon passes, we slowly start to see a thin crescent towards the western night sky. Then the crescent Moon waxes starts to show wider each night. Then the first quarter moon come along. From Earth’s point of view, we start see to see the bright/sunlit side of the Moon. When more of the disc is irradiate, the shape of the Moon is starting to form called gibbous. The gibbous Moon starts to grow faster and we start to see a full Moon. This part of the phase is called the full Moon. The Moon rises almost completely as the Sun sets and sets just when the Sun rises the following day. The Moon is now finalized one half of the lunar month. Next comes the second half of the lunar month. The Moon grows more narrow each night, but the shape is still a gibbous just the Moon gets thinner each night. As the Moon reaches the three-quarter goal during the month, the Moon shows us one side of the Moon’s disc. As the Moon completes its expedition, then the Moon approaches a new Moon again, which is called a waning

The moon is a strange thing. It has fascinated people is well, as I heard it, from the start of time. The moon had not been for one man, the moon would have not have been explored, that man’s name was Wernher Von Boron. But more of him another time. This essay is all about the phases of the the moon. The moon is just a small plant that rotates around the earth. It is not classified as a planet because it rotates around a larger object that is not a star. It also has no atmosphere.

The Milky Way is the galaxy that contains our solar system. Its name “ Milky” was derived from its appearance as a dim glowing band arching across the night sky whose individual stars cannot be distinguished by the naked eye. The Milky Way is a barred spiral galaxy, which means it spiral out from the middle.

Also, looking at the diagram (and imagining it to scale), you may have wondered why, at a new moon, the moon doesn 't block the sun, and at a full moon, why the earth doesn 't block sunlight from reaching the moon. The reason is because the moon 's orbit about the earth is about 5 degrees off from the earth-sun orbital plane.

Star: A self-luminous celestial body consisting of a mass of gas held together by its own gravity in which the energy generated by nuclear reactions in the interior is balanced by the outflow of energy to the surface, and the inward-directed gravitational forces are balanced by the outward-directed gas and radiation pressures.

A star is a sparkling bundle of gas bound by gravity into a solitary object and is fueled by atomic combination at the center. There are trillions of stars in our universe and all are distinctive and extraordinary. Their mass, color, shape makes them all distinctive but mass is the only thing that makes them unique. There are numerous phases of stars life including main sequence stars, red giants, white dwarfs, neutron stars, and dark holes. All stars additionally have a lot of varieties in each one phase of life. The life of a star starts in a cloud, an incredible gathering of gas and dust. When enough mass has aggregated into a solitary item, gravity compels the mass to crumple into the middle. Because of weight and rubbing, the center gets so hot that it starts atomic combination and a protostar is made.
