solar street lighting system What are the Wonders of the Universe?

Anyone can look up at the night sky and appreciate the magnificent splendor of the sky, but if you can identify some planets, how interesting it would be, you can see stars and constellations at different times of the year, know where to find them.It is not difficult to do this;You don't even need any special equipment, although it will be convenient for a pair of binoculars or small telescopes.The torch is also useful for viewing your chart in the dark, but be sure to choose a clear night and try to find a place to stay away from the bright lights of the street lights.
Our world is one of the nine planets spinning around the sun, the nearest star.The Earth is 93 million miles from the sun, and it takes a year to go around the sun.Some planets spend less time than this;Venus and Mercury are closer to the sun than we are.
It will take longer for laymen to complete their journey, and Pluto, the farthest planet in the solar system, will take about 250.When you look at a planet with meat, it looks the same as a star, but stars always keep their set patterns in the night sky, and planets don't.The word "planet" actually refers to "wanderers ".
If you watch planets frequently every few weeks, you can quickly tell the difference.If the Earth is still, the stars always seem to be fixed in the same place.But the Earth rotates on its axis once a day and moves in orbit around the sun.
This means that the whole sky seems to move in the opposite direction.If you like, you can do an experiment to prove this: put a camera with a shutter open for a few hours at night near the open window (make sure it is in the right position, pointing to the clear night sky --You can find an adult to help you solve this problem.) When the movie is released, you will find that you have a photo of the star footprint showing how far each star has gone.
If you see a bright star in the southwest, usually separate, before the real star appears, it is Venus, called our sister planet, because it is as big as the Earth.For about seven or eight months it looks like a night star and then after a short absence it can be seen again in the SouthIn the same time, East is the morning star.Sometimes on spring nights, if you have a clear view of the western horizon, you can also see Mercury.
Mars is only half the size of the Earth, and the eyes look rather disappointing, but when viewed through a telescope, it can be identified in red due to the desert that covers its surface.It is also possible to see the polar ice caps.Jupiter, the largest planet in the solar system, can see the whole night, from east to south to west, shining in any position.
If you look at Jupiter through a telescope, it looks like a shiny silver coin.You can even see four small spots nearby, which are the main moons of Jupiter.Thanks to Saturn's Halo system, it can look beautiful through a telescope.
Titan, Saturn's largest satellite, can also be seen through small telescopes.Aside from Saturn, Uranus, Neptune and Pluto are three smaller worlds.Uranus can only be seen by the naked eye, and Neptune is shown as a blue disk through a telescope.
Pluto is so far away, it is only a faint spot;A cold and lonely world so far away that some astronomers no longer consider it a part of the solar system.The sun is the source of all life.It's like a huge melting pot that lights up our world.Without its warmth and energy, there is no living thing on our planet.
You can't watch the sun directly.
No permanent eye damage even at sunrise or sunset.You can't look at a telescope or a telescope because it's more dangerous.Instead, you can make a small hole camera, just poke a hole in a piece of cardboard and let the sun's light fall on another card directly behind it;Then you will see the disk of the sun.
The moon is our nearest neighbor.
It's 250,000 miles away.
Only because the sun reflects light, it looks shiny.Look closely and you can see the crater without the help of a telescope.When the moon is half full, try to look at it, and then you will see the mountains that extend from the middle, because the flash light from the sun makes them stand out more clearly.
The moon has many features that are easy to observe.The caldera and mountains have names and are easy to find on clear nights.Sometimes in the months of August, November and December it is possible to see meteor showers, and you rarely see a comet with the naked eye that will appear for a few days traveling towards the sun in a broad orbit, reach the sun from the outer area of the solar system before returning to the deep space of the sun.
The comet is the true nomadic people of the Milky Way.Constellation is a group of stars named long ago;They are given the names of animals or Greek heroes.The most easy to find constellation is probably the Big Bear and The Little Bear, sometimes also known as the Big Dipper and the Big Dipper.
No matter what time of the year, they are always visible from the countries of the North.Polaris is known as Polaris because it is located directly above the Arctic.It is also easy to find because of its brightness.
Another easy-to-find constellation in the winter sky is Orion, which all stars are very bright and looks like a big belt dress.On a clear night, you can also see the Orion Nebula, which is a blurry spot to the naked eye.Further south, Sirius is undoubtedly the brightest star in the sky, sometimes called the Dog Star.
The colors of the stars are also different.Blue is hotter than red or yellow.Our own stars are small and yellow, and they are quite common compared to some of the stars in the universe called red stars.Sometimes in spring and autumn, the Milky Way extending from east to west can be seen;It looks like a dull band with different brightness.
The Milky Way is the galaxy we live in.
All the stars we see in the night sky are part of our own galaxy, but if you look between the constellations in the back seat of the fairy (which is easy to spot, because it looks like a big flying horse, you will find the most distant object our eyes can see --This is the neighboring galaxy of Andromeda.If you look directly above your head on a dark night in November or December, you can imagine it as a hazy spot.The light you see from this galaxy takes 2 million years to reach you.
There's a lot to discover about our universe, and we 've been learning new things.From our nearest neighbor, the moon, to the most distant objects known in the universe, such as meteoroids, there will always be new discoveries.Maybe you can start a document and fill it out with all the information you 've learned when you're looking for a way out in heaven.
