The most ancient spiral galaxy in the Universe is found out


With the help of space telescopes like Hubble, astronomers are trying to penetrate deeper and deeper into the universe's cosmic network. After all, the more you look, the greater the time, and this allows you to see how the universe looked billions of years ago. With the launch and introduction of other more sophisticated technologies, telescopes and observatories, scientists can study the history and evolution of outer space in more detail.

Recently, an international group of astronomers, with the help of the Northern Gemini Telescope from the Gemini Observatory on Mount Mona Kia on the island of Hawaii, discovered a spiral galaxy about 11 billion light-years away.

Using a new method that combines gravitational lenses and spectrum testing, scientists have been able to see an object that existed 2.6 billion years ago at the time of the Big Bang. The galaxy is called A1689B11 and is currently the oldest helical galaxy ever found. Astronomers have made their common discovery on the pages of the latest issue of the journal Astrophysics.

Found a very galaxy A1689B11 allowed the gravitational lens method. This method is often used by astronomers and involves the use of very large objects (eg, galactic clusters) as a type of lens that allows the light of the object behind the lens to bend around. Astronomers watch this light.

In a press release from Swinburne University of Technology, astronomer Tiantian Yuan, head of the research group, wrote:

    "This method allows you to study ancient galaxies with very high optical accuracy and an unprecedented level of detail." We have been able to observe the galaxy, like 11 billion years ago, and have become direct witnesses of the first primitive formation.

Next, scientists used the NIFS spectrometer (the infrared integrated infrared meter), which was installed on the Northern Gemini Telescope, to confirm the structure and nature of the oldest spiral galaxy. This tool was created by Astronomer Peter McGregor of the Australian National University. The world is responsible for calibration and correct operation.

Thanks to the latest discoveries, scientists have received additional information on how galaxies acquire their shape. According to the classification of galaxies created by the famous astronomer Edwin Hubble (Hubble sequence), there are three main types of objects - oval, lenticular and spiral - and also the fourth additional category, called irregular galaxies.

According to this classification, all galaxies begin to form elliptical structures, then are modified and take the shape of spiral, lenticular or irregular galaxies. The discovery of such a very ancient spiral galaxy is especially important to understand when and how the first galaxies began to change their shape from elliptical to modern galaxies.

    "The study of ancient spiral galaxies such as A1689B11 is an important link in understanding how and when the Hubble sequence began." The spiral galaxies were very rare early in the universe, and this discovery opens the door for us to study how the galaxy moves from an extremely chaotic discord to a quieter tablet Like our Milky Way Galaxy, the co-author of the study, Astronomer at Princeton Renwa University, commented.

The most interesting thing about the discovery of the A1689B11 is that this spiral galaxy shows some very amazing features that reveal more details and at the same time force you to ask new questions about this period of cosmic history. As Yuan says, these features contrast sharply with the background of more recent galaxies of the same species.

    "In comparison to the smaller galaxies of the same type, in the old galaxy the new stars are formed 20 times faster, which is almost the same level as in the young galaxies with similar mass that existed in the early universe," says Yuan.

    "Unlike other galaxies of the same era, the A1689B11 has a very good and very high disk that goes very quietly with a very low level of turbulence, a similar kind of spiral galaxies of that era that we have not seen before."

In the future, the team of astronomers hope to conduct further studies of this galaxy to understand its structure and
