Sometimes, looking at the night sky, wonder whether the limits of outer space and how many stars in the Universe. Scientists around the world are trying to answer this question. But over time, it becomes clear that the number of stars in the Universe, more than previously estimated.

Therefore, we can only trace the chronology of beliefs and assumptions about them, including the latest knowledge and research.

Our knowledge of the Universe

Once upon a time, in the time of Plato, the scientific world assumed that the number of objects in the Universe is not different from what we see with the naked eye.stars and constellations Acitively three to four thousand stars. And the idea of space was radically different from the modern interpretation.

During the middle ages there was the first telescope invented by John Lippershey in 1608. Since then it has made possible the observation of remote objects. The scientific community and philosophers of that time sent telescopes into the night sky. From that moment it became clear that the number of stars in the Universe, does not correspond to normal visual observation. They turned out to be much more part of the invisible objects became available to scientists and philosophers, armed though primitive (consisted of two lenses), but more effective than the human eye, telescopes.

Despite this, stars and galaxies on the time taken for one and the same object. Understanding that the galaxy may contain billions of stars, did not exist. And it is strongly distorted understanding of the total number of stars in the Universe.

Technologies and capabilities

One hundred years Later, in the eighteenth century, the power of telescopes has increased tenfold. This has allowed scientists to observe new, previously unseen objects in the Universe. By the time it became available to the observation of the order of a hundred thousand stars. It is the ability to see is always limited to knowing how many stars in the Universe in different period of knowledge of our civilization.

Today the resolution of the optical equipment increased thousands of times. In comparison with the initial thirtyfold telescope Galileo Galilei.

The launch of the space telescope "Hubble" gave the opportunity to increase this figure in 7-9 times.number of stars in the universe Before the eyes of astronomers around the world have opened new spaces of the Universe. According to scientists, to determine how many stars in the Universe need to understand, how many galaxies in it and what are its dimensions. The reason for this is the presence of gravitational forces that hold the stars in the galaxies.

The Visible part of space

According to preliminary calculations, in the field of the visible Universe (about 14 billion light years) there are more than seven trillion galaxies. But scientists believe that nebula and space dust closed about 90% of the objects. Therefore, the figure can easily turn into seventy trillion.stars and galaxy At the same time, each galaxy contains billions of stars. Depending on its size, from a few million to a trillion.

At the moment, the scientific world believes that the visible Universe about 10 to 24 degrees stars. But specifically to say that this is the exact figure, it is impossible. The reasons for this are quite compelling. We can't see all of the objects and don't know the exact size of the Universe, if any. Modern optical technique thoroughly studying the stars and constellations observable space. Allocated and classified the new galaxy. The study performed for each object separately.

The Search for the truth continues

Previously a favorite of astronomers optical method of observation was not able to detect all the objects in the observed region of space.how many stars in the universe Therefore, further studies in the infrared and x-ray range. This work takes a lot of time scientists around the world. And the catalogue is replenished with new objects. The number of detected objects is growing steadily.

For example, in 2014 a new telescope Ultra Deep Field was investigated 1/13000000 part of the observable sky and found about ten thousand galaxies in this area. All of this information requires careful handling and analysis. For further, more complete understanding of the Universe.

Maybe we will understand that our knowledge about the number of stars in the Universe, is wrong. The space is boundless or has a different structure of space. And it may well be that we live in one of the many Universes. Whatever the truth, the human desire for knowledge sooner or later will lead to the answer to the question.
