Level: B1 Scientists using the Hubble Space Telescope made an interesting discovery. For the first time, they found a strange object that is mostly dark matter. This object has gas, but it has no stars. Astronomers call it Cloud-9. It may be a very old part of the universe that never became a normal galaxy. Cloud-9 is different from other objects. It contains gas and is held together by the gravity of dark matter. But there are no stars inside it. This makes it very unique. Scientists think that Cloud-9 could help them learn more about dark matter, which is usually invisible and hard to study. Dark matter does not emit light, so we cannot see it directly. However, it affects other things through gravity. Because of this, astronomers can find it by watching how gas and light behave near it. Cloud-9 is like a rare window into the hidden world of dark matter.
Перевод: This discovery is important. It shows that not all structures in space become real galaxies with stars. Some remain dark
