A new research revealed that the Oort Cloud has a spiral arms that resemble a galaxy. Here are all the details of the discovery.
Scientists, on the borders of the solar system, consisting of icy objects Oort cloud He signed a striking discovery that deepened our knowledge. According to a new study, the structure of the Oort Cloud contains spiral arms that resemble a galaxy. This finding reveals details about the structure of the cloud and the effects of forces coming from outside the solar system.
The structure and origin of the Oort Cloud
The Oort cloud is a structure on the outermost border of our solar system, which is thought to consist of giant planets 4.6 billion years ago, especially from the remains of the formation of Jupiter and Neptune. The inner edge of the cloud begins from the sun to about 5,000 astronomical units (AU) and the outer edge extends to 100,000 AU. This distance is thousands of floors of the average distance between the Sun and the Earth.
The new study argues that the structure of the cloud has a spiral disc features similar to a galaxy. This shows that the Oort Cloud can be a window not only to the limits of our solar system, but also to understand the effect of larger forces on a cosmic scale. The research was carried out using a model created with data obtained from the orbits of comets and gravitational influences outside the solar system.
The Oort cloud cannot be observed directly because the objects in it are small and dark. However, this new model can help us learn more about the formation and evolution of the solar system by understanding the structure of the cloud. Researchers say that examining the structure of this cloud can offer important clues about the early stages of our solar system.
Although NASA’s Voyager 1 spacecraft travels one million miles a day, it will need at least 300 years to reach the Oort Cloud. This clearly reveals the size of the Oort Cloud and how much more it is to be discovered.
