The excellence of the "Gaia" detector is that itEquipped with a super camera called the "billion pixel array", which is described as "Gaia's Eye"It is a digital imaging system created by the European Space Bureau, with unprecedented observation resolution.
In the future, the "Gaia" space detector will continue to scan the sky until the fuel is exhausted in 2025.
It is understood that the data released this time covers "Gaia"The latest data of about 2 billion stars collected include its chemical composition, temperature, color, quality, age, and radial speed (the stars are close or far away from us).
