To illustrate the size of the number 23 zeros after 3, Conroy said that each person has about 50 trillion human cells, and there are about 6 billion people on the earth, and the product of the two is exactly 23 zeros after 3. In other words, the stars in the sky are comparable to the total number of human cells on earth.

Anonymous users2024-02-10The universe is boundless, with countless galaxies. There are more than 120 billion slag stars in the small Milky Way galaxy alone. Even if a person starts counting from birth, he can't count 120 billion until he dies of old age.
According to incomplete statistics in 2005, there are more than 50 billion stars in the Milky Way, in addition to stars and comets, there are also super-large giant clusters.
People always say that there are too many stars in the sky, but in fact, all the stars that can be seen with the naked eye can still be counted.
Astronomers divide the stars in the sky into 88 constellations according to their regions. Among them, the northern sky (bounded by the celestial equator) has 29 constellations; There are 46 constellations in the southern sky and 13 constellations in the north and south of the celestial equator. As long as we have patience and count the stars in one constellation, we can count the stars that can be seen with the naked eye.
According to the calculations of astronomers: 6 stars of magnitude 0; 14 stars of 1st magnitude; 46 stars of 2nd magnitude; 134 stars of 3rd magnitude; 458 stars of 4th magnitude; 1476 stars of 5th magnitude; 4,840 ...... of 6th magnitudeNo more than 7,000 in total.
If we use a telescope, the situation is different, and even with a small astronomical telescope, more than 50,000 stars can be seen. The largest astronomical telescope in modern times can see more than 1 billion stars.
In fact, the number of stars in the sky is much more than that. The universe is endless, and what modern astronomers see is nothing more than a tiny, tiny part of the universe.

Anonymous users2024-02-09How much do you know about the starry sky.
About 3 after 23 zeros.
Peter of the American astronomer at Yale University. Fan. Dokun and Charlie, an astrophysicist at Harvard University. Conroy analyzed the intensity of light from galaxies and concluded that there were far more red dwarfs in galaxies than previously thought.
Previously, astronomers estimated that the number of stars in galaxies was about a trillion times that of 100 billion.
Fan. After observing distant galaxies in Hawaii with the help of electron astronomical telescopes, Dokun and his team found that the stars of these distant galaxies were many times or even dozens of times larger than previously thought, and that the size of 3 was followed by 23 zeros. For the sake of the image, Conroy said that there are about 50 trillion human cells in each person and about 6 billion people on the earth, and the product of the two is exactly 3 followed by 23 zeros.
In other words, the stars in the sky are comparable to the total number of human cells on earth.

Junk goods
There are around 6,000 stars visible to our naked eye. But only a small part of the universe. >>>More
On a clear night, when we look up at the sky, we will see dense stars all over the sky, can we count the twinkling stars with the naked eye? There are more than 6,900 stars in the sky that can be seen with the naked eye. However, because it is at night, only half of the sky can be seen, so only about 3,000 can be seen with the naked eye on the earth. >>>More
Is it a popular science problem? If you look at it with the naked eye, you can see more than 6,000 of them, but half of them are in the other hemisphere, so you can see about 3,000 of them with the naked eye at night. >>>More
Some of the stars in the sky are stars, some are planets, or some other celestial bodies. Stars naturally emit light, while others do not. >>>More
The only galaxies that can be seen are the Andromeda Galaxy, M51, and the Large and Small Magellanic galaxies. Most of the sky is filled with Milky Way stars and solar system planets, as well as a few nebulae and star clusters in the Milky Way. Because we are inside the Milky Way, there are not many extragalactic galaxies that can be seen with the naked eye. >>>More
