Everything else in the galaxy revolves around this powerful gateway to nothingness. In its immediate surroundings is a tightly packed region of dust, gas and stars called the galactic bulge. In the case of the Milky Way, this bulge is peanut-shaped, measuring 10,000 light-years across,accordi...
It lies on the far side of the galaxy from us and is heavily obscured by the intervening gas, dust and stars. It is approximately 78000 light years away and about 10000 light years in diameter. It is orbiting our galaxy in a period of about 1 billion years but it cannot be expected ...
The Milky Way Galaxy is an immense and very interesting place. Not only does it measure some 120,000–180,000 light-years in diameter, it is home to planet Earth, the birthplace of humanity. Our Solar System resides roughly 27,000 light-years away from the Galactic Center, on the inner ...

Milky Way plane means that dust obscures those that are more than a few thousandlight-yearsfrom the Sun. Byanalogywith open clusters in external galaxies similar to the Galaxy, it is surmised that they follow the general distribution ofintegratedlight in the Galaxy, except that there are ...
Thegalaxyis surrounded by a huge hot-gas halo that is several hundreds of thousands of light-years in diameter. Astronomers estimate that the halo's mass is about the same as that of all the stars in the Milky Way. Many of the Milky Way's stars, however, are tough to view. That is...

The diameter(半径) of the Milky way is about 100000 light years. It is so big that light takes100000 years to cross from one side to the other.The Milky way galaxy is a spiral galaxy(旋涡星云). It is called a spiral galaxy because it haslong arms. The sun is a star in one of ...
The Milky Way is a barred spiral galaxy 100,000–120,000 light-years in diameter containing 200–400 billion stars. It may contain at least as many planets.[7] The Solar System is located within the disk, around two thirds of the way out from the Galactic Center, on the inner edge of...
Just over half-way through its five-year mission, Gaia's two telescopes have located a billion stars. That's still only one percent of the Milky Way's estimated stellar population, scattered over an area 100,000 light years in diameter. ...
