Three times the amount of water in the Earth's oceans.  Discovery in a nearby system

Most of our planet is covered by water, and Earth's oceans are really vast and contain a lot of water. Meanwhile, astronomers found it in much larger quantities in a very nearby system containing a young star very similar to the Sun. Initial observations revealed his presence there Several times more than water on Earth.

Let's start with the fact that HL Tauri is not a new discovery. This young, sun-like star is located About 450 light-years away. It's not very close, because we're about 4.2 light-years away from the nearest star (Proxima Centauri), but in terms of cosmic distances it's still in our backyard. After all, the radius of the entire galaxy is 105.7 thousand. Light year.

HL Tauri is located in the constellation Taurus, and the current appearance of this system is well reflected in the video released by the European Southern Observatory a decade ago, which you can watch below. When you zoom in, you can see what looks like rings. this Protoplanetary disk It orbits a star, which will eventually form into planets. There astronomers found something very interesting.

Close examination of the protoplanetary disk (inner) revealed its presence Three times the amount of water compared to all of Earth's oceans. And then The form of water vapor It especially occurs during a disc fracture. why there? Scientists suspect that he is infected with it Relationship with planet formation.

Astronomers say that this fracture may be caused by the formation of a planet. The object needs a lot of material during the creation process and this creates disk space. This discovery is very important for better understanding the history of the solar system.

z HL Tauri system It is similar to the early solar system about 4.5 billion years ago. The star there resembles a young sun, and similar conditions may exist in our region of space. Scientists want to take a closer look at this area and try to answer questions about the role of water in the formation of the planet. Similar phenomena may have accompanied the formation of the Earth.

A network of radio telescopes was used to make this discovery Atacama Large Millimeter/Submillimeter Array (ALMA) is located on the Chajnantor Plateau in the Chilean Andes. The facility is managed on behalf of Europe by ESO (European Southern Observatory), to which Poland also belongs.
