Paris: The European Space Agency (ESA) have released the most comprehensive map of our galaxy Milky Way, they have accurately mapped the location of 1 billion and 100 hundred million stars.
This map of Milky Way has been made by the space mission called “Gaia” during the first 14 months of constant observation of the galaxy.
If we compare this map with the previously known map which was made by the space mission “Hipparcos” we will find out that it is at least 20 times larger than the previous one.
Almost 400 million of the 1 billion stars are newly discovered and were unknown before meaning that the actual size of Milky Way is much larger than previously perceived.
More than 450 astrologers and software engineers are part of the Gaia mission, the telescope is equipped with 1 billion pixel camera, it is so powerful that you can see something as thin as human hair from 1,000 kilometers.
Previously the Hipparcos mission was considered the most powerful mission and it has calculated the distance between stars of 80 clusters almost 1,600 light years away from earth.
But Gaia mission can look further beyond, it is able to calculate the distance between stars of 400 clusters almost 4,800 light years away from earth.
According to estimates the least number of stars in Milky Way is 100 billion and the highest possible numbers of stars is 400 billion.
Milky Way is spiral galaxy and its almost 80,000 light years wide, in dark nights especially when there are no clouds Milky Way looks like a foggy cloud.
But Gaia mission has shown that the width and overall size of Milky Way is much bigger than previously thought and it will be only decided in the future by further research.
