7 beautiful phenomena of the sky

The bright strip of the Milky Way. The Milky Way is a giant collection of about 200 billion stars whose sun is one of them. The Vietnamese people used to call the bright strip of the Milky Way. We are located near the edge of this galaxy so it is easy to look towards the center of the galaxy's main disc during the summer nights. If there is a small binoculars or telescope, viewers should use it to observe the light strip and see that it is a set of light spots that each spot is a star and will look much better when viewed with naked eyes.

Meteor shower. The phenomenon occurs when the Earth reaches the orbit with many small meteorites, often the result of a comet passing through Earth's orbit. The gravitational pull of the planet causes many of these asteroids to strike the earth's atmosphere, which rubs against the atmosphere and ignites into streaks of light called meteors. Many light streaks like each other create a meteor shower phenomenon (meteor shower). Meteor shower is quite common and occurs annually, each year more than 10 meteor showers are large and small. When it is not raining, cloudy conditions are easier to observe, especially for people far away from the city lights. (Photo: NASA)

Eclipse / eclipse. The earth moves around the sun, while the moon moves around the earth, which sometimes leads to the earth obscuring the light from the sun reaching the moon and darkening it (eclipse) and sometimes the moon intervenes in the middle to obscure the sun, so when the viewer looks at the sun, only the black color (eclipse) is seen. These are two popular astronomical phenomena, almost every year astronomers love to observe. (Photo: Space)

Observe Jupiter and Saturn through telescopes. Jupiter and Saturn are the most observable planets through telescopes. No need for very modern and expensive telescopes, but only for medium-grade amateur glasses, or even homemade glass (reflective glass with high quality and relatively high magnification) observer Can see pictures of those two planets. Viewers try to observe and identify four bright dots near Jupiter, its 4 Galilei satellites. In the picture are satellites Europa (smaller) and Jupiter. (Photo: free-review.net)

Observe the comet. Comets move around the sun in a long cycle, so comets are bright enough to see clearly with very little eye. However, in each person's meeting, being at least once observed is not too difficult. If there is a chance, the viewer observes a bright comet through a telescope, it is certainly an interesting thing of the universe that we should not ignore. (Photo: astronet.ru)

See the aurora. The aurora occurs because the earth is a planet with a strong magnetic field, when currents of charged particles in the solar wind collide with the magnetic field of the earth, they follow magnetic lines that strike the gas. The polarity of the earth, causing a beautiful scene of colorful bands of light (usually blue).

This is a fascinating astronomical phenomenon. However, viewers can only observe it when standing at the polar region of our planet.(Photo: National Geographic)

The sun is blue (or blue). This special phenomenon has an English name of "Green Flash". It happens when the sun is very low, only a small part emerges from the horizon, a very small part of the upper edge of the sun appears blue for 1 to 2 seconds, very different from the usual color. .

The cause of this phenomenon is due to the dispersion of light in the atmosphere when light from the sun passes through the thick air layer, light rays of different wavelengths (corresponding to different colors) are refracted with the Different corners. When the sun is in a low position, close to the horizon will have a part of red light (and the near-red colors) that cannot reach the observer's eyes while the blue part of the light is more refracted so it will reach the observer. .

The "Blue Sun" phenomenon is easier to catch on the west coast, when the sun goes down. Vietnam has an east coast, so the ability to catch phenomena is very difficult.(Photos: Wikipedia)
