"Milky Way"

Further research shows that this mysterious force accounts for 68.3% of the total mass energy of the universe, and it is because of this that it is able to overcome gravity and become the dominant force controlling the operation of the universe

Scientists using modern observation equipment have determined the size, position, distance and other data of most of the objects in our galaxy

In the Milky Way, the closest stars to the Sun are 4.22 light years away

The solar system is located in a region with a stellar density of only 72 million parts per million of the highest stellar density region in the Milky Way, which is a remote and inhospitable part of the galaxy.

An in-depth analysis of the light from these quasars using the Hubble telescope has shown that the Andromeda galaxy's "halo" has two nested gas shells, with the "inner shell" extending outward by about 500,000 light-years and the "outer shell" extending by up to 2 million light-years

Ever since humans began to look up at the stars, they have been curious about the vastness of the universe, and this is still the case today. With the help of various observation devices, modern humans can take a large number of photos of the deep space of the universe, which are updated almost every day.
