An international group of scientists under the leadership of the University (Unige) has discovered a huge spiral galaxy similar to the Milky Way, which was formed only 1 billion years after the Big Bang, but at that time it had an unexpectedly mature structure.
This detection made using the data of the James Webb space telescope changes the idea of how the galaxies have been formed and developed in the early Universe, reports Service Service High Press.
Large spiral galaxies, such as the Milky Way, will take several billion years. The galaxies of the first billions of years of space are considered small, chaotic and wrong in form.
Nevertheless, James Webb begins to reveal a completely different picture. Its deep infrared visualization shows surprisingly massive and well -structured galaxies, much earlier than expected earlier, which encourages astronomers to rethink how and when the galaxies form in the early Universe, the article says.
One of these galaxies – the most distant candidate of a spiral galaxy determined today – is observed in the field of space, which corresponds to only 1 billion years after the large explosion. Despite this early era, the galaxy has an amazingly mature structure: the central old bulge, a large star disk and spiral hands, which makes it look like our Milky Way.
The galaxy was called Zhólóng (Zhulin) – in honor of the dragon in Chinese mythology. In the “Myth of the Juline” a powerful red sunny dragon, which creates during the day and night, opening and closing his eyes, symbolizing the light and space.
What is different from Zh push is how much it resembles the Milky Way – both in shape, size, and in star mass, ”the researchers emphasize.
The ZHYLóNG disc covers more than 60,000 light years and contains more than 100 billion solar masses in the stars.
This makes him one of the most convincing analogues of the Milky Way that have ever been discovered in such an early time, raising new questions about how massive, ordered spiral galaxies can be formed so quickly after a large explosion, the article says.
