Scientists were shocked by their discovery that our galaxy is twisted and distorted. The oldest badumption was that the Milky Way galaxy around our world was relatively stable and flat, but for the first time, astronomers could accurately map the galaxy to reveal that it had become distorted and increasingly twisted at the approach of the edges, reported The Independent.
It was difficult for scientists to see the shape of our galaxy at a time when they were able to map out other galaxies and why our world was stuck in the middle of our galaxy and hard to see. Scientists compare measurements of the Milky Way to a person standing in the garden of his house and tries to determine the shape of his country.
Researchers have now used 1339 stars to map the actual shape of our galaxy and discover that the star disc rotates upward as it approaches the edge, in contrast to the flat shape observed by scientists from other galaxies.
Astronomers generally regard helical galaxies as flat galaxies such as Andromeda, which we can easily see at the telescope, said Professor Richard De Grace, a member of the team of researchers and astronomers of Macquarie University in Australia, quoted by The Independent.
If we look at our galaxy from the outside and far, we will see a thin disk of stars orbiting a central area for several hundred million years. There are hundreds of billions of stars and a huge amount of dark matter blending into a mix.
However, the further one gets from the interior of the Milky Way, the more the force of gravitational attraction decreases, so that the hydrogen atoms forming the gas disk of the Milky Way are twisted in the form of the outer disk and are no longer related to each other.
Scientists have speculated for decades on the fact that the removal of hydrogen in our galaxy may have a strange shape, but the new study shows that the deformed disc contains young stars and confirms that the twisted spiral of the Milky Way comes from the torque or strength of the wicks that appear when the gigantic internal disk rotates.
The head of the Xiaodian Qin research team of the Chinese Academy of Sciences of Beijing said that it was difficult to determine the distance between the sun and some parts of the gas disk outside the path milk without the scientists having a precise idea of the shape of the real dance.
Astronomers have already observed similar galaxies in their fringes, although they are rare but unknown until our galaxy belongs to this group of galaxies of extraterrestrial form.
