The team of scientists based on the "Gaia" space observatory of the European Space Agency "ESA" announced the release of a new package of data through the observatory, sufficient to adopt the most accurate map possible of the Milky Way now, which will help astronomers around the world to identify our cosmic ocean With unprecedented precision.

Historical accuracy

The results, announced by the agency in an official statement, came to say that the new version of the Gaia EDR3 Space Telescope carries information about 1.8 billion stars.

Compared to previous versions, this is the largest number of objects studied by the observatory.

In 2018, it released data about 1.7 billion celestial bodies, and in 2016 the space observatory was working on about 1.1 billion stars.

But the most important thing is the degree of accuracy that has doubled compared to previous versions of the Jaya telescope, especially in determining very important parameters for astrophysicists, such as the distance between us and those stars, their movement in space, and their position in relation to us on Earth, with an accuracy similar to determining the position of a hair at a distance of a thousand kilometers.

Hipparchus was only able to track about 120,000 stars (ESA).

The legacy of Hipparchus

The "Gaia" mission was launched on board the "Suez" missile in December 2013, specifically from the French Guiana region, which is located on the northern coast of South America.

From the very first moment, the goal of the observatory was to complete previous important work launched in 1989, namely the Hipparcos observatory of the same agency, which was only able to track about 120 thousand stars.

The more stars we know in a 3D space atlas, the more accurately we can understand their nature, their past, and thus their future.

It is similar to studying the citizens of a country, so the more you can accurately identify the largest number of them and the daily movements, the more you will be able to understand the entire country.

Every time new data comes out on JIA, star physicists test a new tsunami of knowledge (ESA).

Violent history

According to the European Space Agency, these new data barely appeared until it was accompanied by new research results that open the door for more in-depth understanding of the nature of our galaxy.

For example, scientists are now better able to understand the nature and evolution of the fringes of the galaxy over the past 10 billion years.

On the other hand, these new results opened the door to the most accurate study possible of the orbit of the solar system around the center of the galaxy, and gave a huge amount of data about the two Magellanic clouds, which are two irregular dwarf galaxies close to our galaxy by astronomical standards, as they are located at a distance of only about 170 thousand light years.

And this is just a tip-off, since its launch, the Jaya observatory has contributed to enriching thousands of research results, the most important of which was several years ago when its data indicated that the Milky Way had a very violent history, as it formed through the fusion of several galaxies together.

The observatory was also able to confirm that these previous conjunctions were what triggered the galaxy to create new stars at high rates, and from those stars the sun was perhaps.

And every time new data comes out on Jaya, star physicists test a new tsunami of knowledge.
