LucisFerrerLooking at the beautiful starry sky, people always have all kinds of reveries, just as you open this article with the same mood. Now, you can watch the starry sky on your mobile phone without leaving home. Let me introduce how to use the mobile phone star map. At present, Stellarium and star map are mostly used.
First of all, just like a map, the sky will also have its own coordinates. The latitude corresponding to the latitude on the earth is called declination in the sky, and the longitude is called right ascension. The right ascension line is defined by extending to infinity along the polar axis of the earth and connecting the two ends of the line with an arc on the spherical surface similar to the longitude. The right ascension is to expand the latitude of the earth into the sky, and the line with the expansion of the equator is called the celestial equator, and the zero degree of the right ascension in the sky will not be set on the coordinates of the Greenwich Observatory again, Therefore, people locate the vernal equinox (near Aries, but the position of the vernal equinox has changed over time) at 0 ° of the right ascension, so that we can well describe the position of stars in the sky.
As shown in the figure, Polaris is a well-known star at 90 ° declination. It does not change because it is on the polar axis. In addition, the belt Samsung is about on the celestial equator, so we can find it by understanding the coordinates or relative positions of stars (of course, the best way is to remember the positions of many major stars).
Then, one of the advantages of the mobile phone star map is that we can accurately see the attribute parameters of stars and planets, as shown in Betelgeuse 3 below. We can click it to find the magnitude, distance and star type.
Because celestial bodies are moving in a diurnal fashion, we can see different skies at different times. However, according to the current star map software, we can input different times to deduce the future celestial phenomena, so as to decide how to observe or shoot (except for the incorporation of overcast religion in the community)
Another advantage of electronic star map is that it is convenient for novices to remember and find constellations. As shown in the figure below, we can use the search function above. As long as we input the correct star name, we can find the desired stars. In addition, we can connect the stars between constellations to facilitate pictographic memory and speed up the novice's memory speed.
If you are in the wild, you can switch to the night mode of most star map software. In this mode, the page will become dominated by the red light with less strong response of human eyes, so as to prevent the stimulation to the eyes in the wild and reduce the time for the eyes to recover to the darkness due to looking at the screen.
Later, the star map can observe not only stars, but also deep space objects. The objects represented by Messier Objects are the most gorgeous scenes in the sky. Most of these objects are composed of open star clusters, globular star clusters, nebulae, galaxies and so on. They usually have gorgeous colors, but because they are far away from the earth, they are difficult to be observed by the naked eye, even with telescopes, Sprouting newcomers who are not familiar with their positions are also difficult to find their positions easily with telescopes. Some of the star maps can mark them for our observation and memory, just like the Pleiades star cluster mentioned repeatedly in previous activities.
In the star map, we can often see the magnitude of stars. Here, the magnitude represents the apparent magnitude, which is related to the absolute magnitude of stars and the distance from us. At first, people divided the brightest star and the darkest star into six grades. Later, people measured and proved that the brightest star is 100 times brighter than the darkest star. Here is the origin of the apparent magnitude. The smaller the magnitude, the brighter the star.
In addition, some star maps have ecliptic lines, which can make Mengxin convenient to find the twelve zodiac constellations. At first, people thought that a constellation could not be seen in a certain month, so they thought that this constellation came to earth. In fact, the constellation was covered because the sun moved like the sky area. Of course, as time passed, Ophiuchus was mixed into the zodiac, resulting in changes in the position of people's constellation and the current sun.
The above is the basic usage of most star maps. Finally, although the sky in the mobile phone is very beautiful, it doesn't shock and move us when we stand under the sky.
