How many galaxies are there in the universe and how many galaxies are there in the universe

Uranus, Neptune, Mercury, Venus, Jupiter, Mars, Saturn, Pluto, ·· There are about 5 billion extragalactic galaxies that have been discovered, and together with our own Milky Way, collectively known as total galaxies, represent all the cosmic ranges that humans have come into contact with so far. But the universe itself is infinite and expanding, so there should be an infinite number of extragalactic galaxies that we don't yet know. There is no exact number of how many galaxies there are in the universe, some say more than 80 billion, some say more than 100 billion, some say 1000 200 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.

The final result should be unknown!!

In addition to the Milky Way,+ there are many star systems that resemble the Milky Way in large and small, called galaxies. There are at least 100 billion planets in the universe.

The universe is endless. Only a small fraction of the galaxies have been discovered now. It's infinitely many.

Humanity is still inconclusive.

There are more than 100 billion galaxies in the universe. According to their shape and structure, they can be divided into: spiral galaxies, barred spiral galaxies, elliptical galaxies and irregular galaxies.

The total number of extragalactic galaxies is estimated to be more than 100 billion. The most common classification of extragalactic galaxies was proposed by Hubble in 1926. The discovery of extragalactic galaxies has expanded human understanding beyond the Milky Way galaxy for the first time, and is an important milestone in the process of human exploration of the universe.

Galaxies, also known as extragalactic galaxies, are galaxies that are made up of a large number of stars outside the Milky Way. Because of the distance, it appears as a vague point of light on the surface, so it is also called the "extragalactic nebula". Extragalactic galaxies, like the Milky Way, are made up of a large number of stars, star clusters, nebulae, and interstellar matter.

About 1 billion galaxies similar to the Milky Way have been observed.

Since the invention of telescopes in the early 17th century, human vision has expanded to the depths of the universe farther and farther, and astronomers have discovered some cloud-like objects, known as "nebulae". Some "nebulae" are gaseous, while others are thought to be cosmic islands of many stars, like the Milky Way.

Because they are so far away from Earth, they can't distinguish the hazy objects made up of a large number of stars. In the 18th century, the German philosopher Immanuel Kant and the British astronomer Wright and others speculated that these nebulae were cosmic islands composed of asterisms like the Milky Way, and they were too far away to distinguish individual stars. The discovery of extragalactic galaxies dates back more than 200 years.

Hello dear. There are more than 100 billion galaxies in the universe. In the observable universe, the total number of galaxies may reach more than 100 billion (Zhizhen 1011).

Most galaxies are between 1,000 and 100,000 parsecs in diameter and in the order of millions of parsecs from each other. Intergalactic space (the space that exists between scattered galaxies) is filled with extremely thin plasma, with an average dense impulse of less than one atom per cubic meter. Most galaxies are organized into larger groups, known as groups or clusters, which in turn aggregate into larger superclusters.

These larger groups, often referred to as large-scale fibrous structures, are distributed around huge holes in the universe.
