The secret of the star is revealed in the heart of our galaxy

Billions of star-studded galaxies wander through interstellar space, and our own large spiral galaxy is like other similar galaxies. As we look up at the clear night sky, we see a seemingly endless dark background, a flame of distant anger shining with countless stars - if we are fortunate enough to stay away from the glare of city lights, we can observe our Milky Way as A starry sky, across the sky, tells us that we are a small part of a huge and mysterious thing. The sparkling stories of the stars provide important clues about their age, composition, and even their birthplace. a stellar prisoner living in the ancient center of our galaxy from

 It provides a treasure trove that shows how our starlight - the shape of the windmill in the shape of a windmill - is the home of the space islands of many stars - quietly telling clues about how they evolved over billions of years. On January 11, 2018, at the Winter Meeting of the American Astronomical Society held at the National Harbor in Maryland, a group of astronomers announced their new discovery of the Milky Way from

 It is a vibrant environment with stars of all ages. These stars fly at different speeds in the secret heart of our galaxy.

For a long time, astronomers thought of our galaxy from

 It is a quiet, peaceful old-fashioned star residence. These ancient stars are the first stars they lived in in our young galaxy. However, the new study has about 10,000 normal sun-like stars inhabiting this. from

  The faster stars of the younger generation may have reached the heart of the Milky Way because our Milky Way has had terrible fever on smaller, unfortified galaxies. However, young stars dance with older, slower stars. At this time, only from

Because the secret heart of our galaxy is so crowded, it has always challenged curious astronomers. This is because it is very difficult to solve the chaos of stellar movement. from

 According to the authors of the study, studying the wild, complex and chaotic heart of our galaxy may provide important new clues as to how our galaxy evolved.

Part of the galaxy

Our Milky Way has about 200 billion stars and lots of other objects. This is a majestic sight when viewed with binoculars on a dark night away from the city. Thousands of stars can be observed to perform their hot, glamorous dances in space in each field of view.

At the moment, our thoughts on the nature of the Milky Way are based on a more solid foundation based on our ancient creatures creating cute fairy tale myths and stories to explain the existence of this celestial star band. The Milky Way has been extensively studied by astronomers, turning their scientific instruments to the dazzling fireworks display in the sky.

Before the formation of the Milky Way, the universe was filled with most of the hydrogen - and a small amount of helium. Gas history has experienced oceanic changes to Mars, along with the accompanying planets, and conscious beasts, such as ourselves on Earth - and possibly elsewhere. However, before this important metamorphosis may occur, our galaxy already exists.

The Milky Way we live in is now very different from the cold gas that emerged billions of years ago. In the first few years of its existence, our Milky Way was a ball of hydrogen. However, astronomers currently using radio telescopes have been able to determine that our Milky Way is a giant spiral galaxy - a starlight windmill that spins in space - just one of many other galaxies. Despite this, astronomers are at a disadvantage. This is because we are inside the Milky Way, which makes it impossible for astronomers to observe it as a whole. All of this has a bright side - astronomers can stare at intergalactic space and study distant galaxies like ours.

- Stars, gas and dust: There are various types of stars: the elderly, the newborn, the middle-aged, and the young.

 It may be younger, and its chemical composition is richer than the heavier elements of the deaths of previous generations of stars, and they should exhibit different movements than the old ones.

The astronomers then continue to classify the stars based on their chemical composition and compare the engines of each observation group from there. They identified the stars by observing their color to obtain chemical composition and then dividing them into two main groups based on their heavy [iron] abundance. Astronomers have found that chemically enriched stars travel twice as fast as other stars.
