Knowledge of the universe latest !! 1. Tell me that I will definitely give a reward for wealth

Recent research has shown that there may be other universes.

The phases of the moon cause bio-tides.

1. The geography textbook of the first year of high school says that there are 1 billion.

In 1995, astronomers used the Hubble Space Telescope to observe outer space in the north and estimated that there are about 80 billion galaxies in the universe. Three years later, in October 1998, observations were made in outer space in the south, and the number of galaxies in the universe was estimated to be 125 billion.

The reason why the figures for the two observations differ so much, explained by Harry Furguson of the American Space Telescope Science Institute, is due to the fact that the observation distance of outer space in the south is greater than that of outer space in the north.

From this, we can know that there are more galaxies in the universe than 125 billion, because the Hubble Space Telescope does not see the edge of the universe.

2. The size of a galaxy is not measured by the number of stars, but by its mass or extent.

On October 30, 1990, American astronomers observed a galaxy 6 million light-years away from the Milky Way, about 60 times the size of the Milky Way. This is the largest galaxy ever discovered.

According to the American magazine Science, this galaxy is located at the center of a galaxy cluster and is called: "Abell 2029". It has more than 100,000 trillion stars, compared to 200 billion stars in the Milky Way.

Minimal mass. According to Science ****, American scientists recently found the smallest galaxy in the universe, with a mass of about 10 million times the mass of the sun.

A professor of astronomy at the University of California, Irvine, recently successfully found the least massive galaxy in the universe by observing the light emitted by galaxies, which is about 10 million times the mass of the sun and belongs to white dwarf galaxies. According to scientists, we have found a group of white dwarf galaxies, which are made up of dozens of smaller galaxies, and although these galaxies vary in size and brightness, the mass of these galaxies is surprisingly consistent, each 10 million times the mass of the Sun. of galaxies, the mass is about 10 million times the mass of the Sun.

The range is minimal. These galaxies were once listed as Ultra Compact Dwarfs (UCDs), which are 1 or 2 orders lighter than the mass of ordinary dwarf galaxies, and their size fits perfectly between the solar system and the constellation Orion, i.e. it is about 500 light-years in diameter. Most likely, these small galaxies were formed from ordinary dwarf galaxies, whose outer stars had captured neighboring larger galaxies.

3 How many there are are difficult to say.

A new study says there could be at least 100 billion planets in the Milky Way galaxy alone, a number far beyond what people previously thought.

This means that on average, there is at least one planet around each star in the Milky Way, according to a report published in the new issue of the British journal Nature. Therefore, the presence of planets around stars should actually be a common phenomenon, not an uncommon phenomenon as it was thought in the past.

There are more than 200 billion stars in the Milky Way.

Countless unknowns unknown.

Unknown Unknown Unknown.

The universe is like the earth, how many deserts there are on the earth, how many grains of sand there are in the desert, then there are as many planets... The rest, you can imagine.
