With the help of the WebB space telescope, astronomers were able to reveal a long -standing riddle about how planets could appear in the early universe. This riddle arose after more than 20 years ago the Khabble space telescope discovered the oldest famous planet in the Universe, which was then formed in the history of the Universe, when it could not appear, as astronomers believed. The study is published in The Astrophysical Journal, Live Science writes.

Stars are created from huge gas molecular clouds. After the star appeared, then the rest of the gas, as well as dust, envelop it in the form of a protoplanetary disk in which planets are formed. Astronomers believed that one of the first stars in the universe could not have planets, because protoplanetary discs did not contain enough heavy chemical elements, such as carbon and iron. These and other heavy chemical elements are created in the nuclei of stars as a result of thermonuclear synthesis, as well as as a result of the death of a star in the form of an explosion of supernova. Astronomers believed that heavy chemical elements are necessary so that protoplanetary discs could exist for a long time and do not dissipate and thus this leads to the creation of planets. If protoplanetary discs cannot exist for a long time, then the planets cannot have the stars in the early universe.

But in 2003, with the help of the Hubble space telescope, astronomers discovered in the Milky Way at a distance of about 5,600 light years from us a massive planet, which revolves around the star in the star of the star cluster M4. Ball star clusters are one of the oldest objects in the universe, and therefore there are practically no heavy chemical elements in them. Nevertheless, astronomers found that the planet called PSR B1620-26B, which is a gas giant, has existed for about 13 billion years. For comparison, the age of the universe is estimated at 13.8 billion years. This discovery showed that the planets in such an early universe could still form, although this was considered impossible.

In order to understand the conditions in the early Universe, scientists can study objects that have similar characteristics to the most ancient galaxies. For example, such an object is the stellar accumulation of the NGC 346 in the neighboring galaxy small Magellanic cloud. This accumulation almost does not contain heavy chemical elements and consists mainly of hydrogen and helium.

Initially, scientists monitored NGC 346 using the Hubble telescope. Astronomers discovered signs that stable protoplanetary discs may exist around the stars for 20-30 million years. This is about 10 times more than the theories predicted. In order to get more data, astronomers used the Webb telescope. The new observation confirmed that even among poor heavy chemical elements, protoplanetary discs can exist for a very long time, which allows planets to form.

Thus, the riddle of the oldest famous planet and planets of a similar age found later was disclosed. That is, the existence of seemingly "

Scientists believe that in ancient stars, protoplanetary discs existed for a long time because the absence of heavier chemical elements could prevent the star from its radiation quickly dispel this disk. Thus, the planets had the opportunity to form. On the other hand, according to astronomers, the molecular cloud from which the star is created can be more, which means that the protoplanetary disk can also be more massive initially, which allows it to exist for a long time.

As the Focus already wrote, the NASA Mark Road made an unexpected discovery on Mars and have not yet seen such an astronomer.

Focus also wrote that scientists argue that the mummies of " The new data, according to scientists, indicate that unknown mummified creatures are really real, and are not a hoax.
