Stars – Pirateering

The term "night sky" is usually related to astronomy on Earth. It refers to the nighttime appearance of stars, planets, and moons in a clear sky when the sun is below the horizon between sunset and sunrise. Stars look small in the night sky because they are far away. Items far away require us to move our heads only a little in order to be seen. This means they have a low angle of visibility. So faraway things appear small because they have a low angle of visibility. Depending on the degree of cloudiness, pollution, humidity and light pollution in the local sky, stars visible to the naked eye appear as hundreds or tens of thousands of white light points in an almost black sky, combined with some faint nebulae or light clouds. The colors of visible stars range from blue (hot) to red (cold), but due to these faint light spots, most of them appear white because they stimulate the rods and do not activate the cones. To solve this problem, constellation photographers sometimes place a diffusion filter on the lens to turn bright stars into particularly large spots. How the Earth's Atmosphere Interferes with Star Sight The Earth's atmosphere can easily disrupt the light from the point of a star. The twinkling, or "twinkling" of stars in the sky, occurs due to movements in the Earth's atmosphere. When observing a star from the surface of the Earth, we also look through the various layers of the atmosphere. When the earth rotates, the stars seem to move from east to west in our night sky. The reason is the same as the reason why our sun seems to "rise" from the east and "set" in the west. The star near the celestial pole, that is, the imaginary point in the space where the north-south axis of the earth points, has a very small rotation circle. So, if you find the North Star, the "North Star" of the earth, you will find that it moves very, very very little in the night sky. Since Polaris is close to a point in the sky above the Earth's rotation axis (North Pole), it is always visible. Why the Sun Is So Much Larger The sun appears larger than other stars because it is much closer to Earth. The stars in the sky look very small because they are either very far from Earth or billions of kilometers from Earth. But the stars are very, very far from our solar system, so they seem to us very small, although they are large up close. Although planets are much smaller than stars, they appear to be about the same size as stars because they are so close to us. They reflect sunlight in the same way that our moon reflects sunlight. Stars shine because … they are so far from Earth that even in large telescopes they appear only as dots. The stars shine because they are very hot (so the fire emits light because it is hot). The stars emit their own light, just like our Sun (the Sun is the star, the closest star to the Earth). The stars emit their own light, just like our Sun (the Sun is the star, the closest star to the Earth). The stars in the constellation seem to be on the same plane because we observe them from far, far away. Each constellation is a collection of stars, distributed in three dimensions in space, and all stars are at different distances from the earth. Constellations Are Made of Bright Stars Some of the brightest stars form clusters in the sky that we call constellations. Constellations are important because their stars tend to be brighter than other nearby stars in the sky. The hottest stars usually appear blue or white-blue, while the colder ones appear red. Sometimes the sky is very clear and dimmer stars are visible, while other times it is a little hazy and only the brightest stars are visible. Likewise, when the Earth rotates, we can see the stars in that position in orbit around the Sun at night and the Sun at the center of the course during the day. As the Earth makes half a revolution in one night, a star visible in the lower east in the early evening will appear to rise and arc in the southern sky and set in the west until morning. The rest of the stars will rise in the east all night. All the stars that can be seen are always in the sky at some time during a 24-hour day, but some rise when the sun is in the sky and are obscured by the bright light of the sky. Why Some Stars Cannot Be Seen The only stars we can't see are the stars behind the sun or the stars that are blocked by the earth below us. If I could see our so-called constellation from elsewhere in the sky (for example, Orion from a planet orbiting the Taurus star), it would look very different from what we see on Earth. The star in the sky is indeed a point, but the image of the star in the camera is not. It shines mainly in infrared light (I think this is where they found the "brown" part, in fact it appears dark red to us), and it is not as bright as other stars. After the start of nuclear fusion, a star can glow for about 10 billion years. "There are several ways to prove to yourself that the light entering the eye from the moon remains the same as the moon, changing its position in the sky. If you look through a telescope, you can think of the planets as disks, and the stars remain point. All stars and objects in space, such as constellations, can be mapped relative to the poles and equator of the celestial sphere. Stars orbit them overnight (or a year). Smaller, lighter stars produce less energy and shine less brightly than our Sun. Larger, heavier stars can produce more energy and shine brighter than the sun. For reasons that scientists are still trying to understand, the mass of most developing stars is significantly less than the mass of the Sun. Except for our Sun, the closest star, Proxima Centauri, is over 4 light years away. Now the heat and light of the star is obliterating the surrounding gas and dust, and the new star can finally be seen in the nebula. By observing the various stars in the cluster, we can see which ones ran out of fuel (and became red giants) and which ones are still glowing as usual. Because astronomers studied the night sky with modern telescopes, they were able to see stars in dark spaces around constellations that were not part of the original star images. These scientists "connected" the dimmest stars between the ancient constellations.
