Use a telescope to track the stars. Illustration: IT. Stay away from lights when observing the sky When using a telescope to observe the sky, determine for yourself reasonable objects and choose the right time and place to observe them. Strong light is the enemy of the astronomical observer. Therefore, stay away from city lights. If you are in the city, you can go to the quiet suburbs if possible. Otherwise, you should choose high positions and have a wide viewing angle to limit the effects of light pollution. Which objects are best for you to observe with amateur telescopes? Many young people after completing the telescope with their own hands feel disappointed. Because you have too much hope for a dream glasses without taking into account the reality factor. Remember, even the glasses that cost thousands of dollars that you order from the world’s leading manufacturers cannot allow you to see the colors shown in the photos taken on Google. Also, pay attention only to the brightest and most observable subjects. Which objects are the brightest? Except for the Moon, readers with basic knowledge of astronomy will think of Venus, Jupiter, Mars or Sirius – the brightest star after the planets in the system. However, Venus is not a good object to observe even though it is very bright. All you see is a yellow halo due to its thick and toxic atmosphere. Stars like Sirius, Canopus, although many times brighter than that, they are just distant balloons. It is not a reasonable target for observation through amateur optical telescopes. The best observed objects are the Moon first, followed by Jupiter, Saturn, Mars and a few galaxies, remarkable nebula. Don’t Observe When The Moon Is Full To observe the Moon, adjust the position of the eyepiece accordingly and aim at the vicinity of the semi-dark area during the nights between the 6th, 7th and 11th of the 12th lunar month. The full moon is a bad subject because it is so bright that it will obscure the craters and valleys you can see. You can solve this with a thin layer of glass called a moon filter, which will reduce the light of the Moon as it reaches your face. With industrial-grade telescopes, most have this. As for the homemade glasses, you can also design it yourself using a glass or a piece of blue plastic but still clear enough to see through it. Even so, the Moon should not be observed on full moon nights. Because in addition to it covering itself, it also obscures other attractive objects of observation, except, of course, on full moon days when the lunar eclipse occurs. You should have a map of the visible part of the Moon to compare when observing. These maps are now easy to find on the Internet and simply print out with any black and white printer. To observe the planets, it is best to choose the right time for good results. Planets have a different period than Earth, so they do not have a stable position like the distant star background. The easiest way is to use computer software to check the positions of the planets, or you can use free software downloaded at www.stellarium.org. Do not forget to set the exact location of the user and when you want to observe. It is advisable to choose days that are not full moons because the planets are in relatively high positions. Jupiter is the most observable object through amateur telescopes. Push your eyepiece a little deeper than when looking at the Moon and try to orient the lens because it will disappear instantly if you don’t keep your gaze exactly. Although it is not possible to see the colors as clearly as in the photos online that have been taken with exposure techniques, and through equipment thousands of times more modern than the amateur glasses you own, the colors Basic with brown lines, dark yellow is what you will see, and moreover the 4 Galilean satellites of this planet. Saturn is like Jupiter, just determine the right direction and fix the glass and you will easily observe it. The most interesting thing to look at this planet is its ring. However, it won’t be as colorful as you’re used to seeing in the photos, both the planet and the ring appear pale yellow. Next in the Solar System is Mars. But observing this planet is not very interesting because all you see is a faint red and maybe some black patches with faint ice caps at the poles if the telescope is relatively good. Anyway, this is the only planet in the Solar System that we can see some of its surface through amateur telescopes. One type of object that is very interesting to observe with amateur telescopes or, more neatly, tubes are bright galaxies and nebulae. Remember to push your eyepiece even further towards the objective so that you can observe the celestial bodies at infinity. The first notable is the Andromeda Galaxy (M31), a spiral galaxy. At a distance of nearly 3 million light-years, it emits light strong enough to be seen with the naked eye. Even with a small binocular you can see a band of light that seems to be a combination of countless small bright dots when directed towards it. What you see is billions and billions of suns like our own. Next is the Pleiades star cluster (M45), also known as the stellar group. It is also easy to recognize with the naked eye, it is a small group of 7 brightest stars located right in the constellation Taurus. Through binoculars or small telescopes, it can be clearly seen that it is a blue star cluster with many stars, including 7 brightest stars visible to the naked eye, so it is called the Seven Stars. This is an open cluster in the milky Way located 400 light-years from Earth. Another member you should look out for is the Orion Nebula (M42), an emission nebula with the same galaxy about 1,350 light-years from Earth. The Orion Nebula, although visible to the naked eye, is quite faint.

Most planets in the universe are not suitable for us to live in. With the current environment in the planets, imagine how, if we humans lived there, the body would change. Mars Gravity is lower on Mars than on Earth and it is further away from the Sun, so if we live on Mars, we will see less sunlight. Mars also lacks a protective magnetic field due to its thin atmosphere, everything there, including humans, is exposed to radiation. Occasionally, strong winds create dust storms that fly across the planet, and dust continues to settle for months to come. So if you go to live on Mars, you may be taller, stronger body to compensate for the poor gravity. You will have big eyes for better visibility when the Sun is too far away. In addition, the main pigment in your body changes from melanin to carotenoids (carrots, tomatoes and oranges). So your skin is likely to be orange. Jupiter Living on the surface of Jupiter is challenging because the planet has no real surface. It is purely air. However, this does not mean it is just a giant cloud suspended in space. If you travel through its atmosphere to deeper parts, the gas will become dense until it turns into a liquid. In a nutshell, Jupiter is an ocean layer made up of hydrogen instead of water. With such high pressure, extreme temperatures and liquid environments, humans would have to mimic creatures that live in deep water. We would be like animals with small legs and hard shells to protect the body from Jupiter’s radiation. Saturn Saturn is also a giant cloud of hydrogen and helium, with no soil or no wind. However, inside it is much denser and much smaller than Jupiter. Its iconic belts are made of countless ice particles, so nothing can live on this planet. The Saturn rings are innumerable ice particles. Saturn’s weight is too small, so it can float in a bath if there is a tub large enough to hold. The only way to get around in the dense mist of Saturn is to hover around like a jellyfish. Your body will not have a skeleton so that it cannot be crushed by the pressure. Mercury Life on Mercury is extremely difficult. This tiny planet is closest to the Sun, so the sunlight here is seven times bigger than Earth, no sunscreen can resist. Mercury’s temperature is extremely extreme, around 430 ° C during the day and -180 ° C at night. The planet is also prone to meteor shower and earthquakes. There is no atmosphere here to breathe. How must we change to accommodate Mercury? Meat and bones can never withstand the harsh conditions here. So to live in Mercury, our bodies must be made of something similar to the refractory metal, for example, titanium. There’s no need for a respiratory system, so your pretty metal face won’t have a nose. And your eyes will be like a thick sunglasses to protect them from the sun’s light. Venus If there’s a place that’s harder to live than Mercury, it’s definitely Venus. The temperature here is a whopping 471 ° C. The atmosphere is extremely thick, creating a greenhouse effect. The planet’s surface is very dry, there are many natural disasters such as volcanic eruptions, hurricane winds and lightning. The pressure here is like you are 1 mile underwater, giving you constant headaches. Unfortunately, the only thing that can exist on Venus is bacteria. Venus corrode everything, even metal, making it impossible for human spacecraft to stop here. Venus’s atmosphere contains phosphine, which is toxic to any organism that breathes oxygen, but is very beneficial for bacterial growth. Uranus, Neptune Frozen, dark and plagued by strong winds, Uranus and Neptune are mostly made up of cold liquids – methane, water and ammonia. They do not have a solid surface, and their atmospheres slowly mix with the water around the cores of other planets. Gravity is stronger here than on Earth and puts more pressure on everything. With such a strong gravity, the human body living here would have to be shorter and muscular, muscular, and thicker in skin to resist the cold. And for the liquid environment here, the best form to live in is a cosmic dolphin or manatee, making it easier to navigate around the planet. The Pluto Pluto is the planet farthest from the Sun, covered with ice and snow. Gravity is extremely weak and the atmosphere is fragile. The sun seen from Pluto is just a dot on the horizon, like the Moon to Earth, so there won’t be much light. However, scientists believe that there may be ocean water below Pluto’s surface. If you live on Pluto, your body needs antifreeze, like some insects and fish. Low gravity causes muscles and bones to shrink, the space between the vertebrae expands and makes us taller. Human posture will also change as the spine is not doing too much. So you can be tall, thin, and somewhat spiderman with flexible limbs and a curved spine.
