The newly discovered system is 100 light-years from Earth, or about 600 trillion (万亿) miles. That’s close, in space terms. Astronomers are calling the system a “golden target” for further study. It could offer an example of how systems across the Milky Way were formed. All solar ...
Studying the Milky Way used to be notoriously difficult. Astronomers sometimes compare the effort to attempting to describe the size and structure of a forest while being lost in the middle of it. From our position onEarth, we simply lack an overview. But two ground-breaking space telescopes l...

If our solar system were the size of a U.S. quarter, the sun would be a microscopic piece of dust and the Milky Way would be about the size of the United States.[1] The Milky Way rotates at a speed of 168 miles per second. So, the actual place in space where you were an hour...
It must not be assumed that all the secrets of the Milky Way have been laid bare; so much still remains to be done that it would be true to say that our knowledge of the Galaxy as well as of the extra- galactic systems is very limited, and many years of patient research will be ...
to a 7-year-old, I’d say that the Milky Way is the galaxy in which we live. It’s a gigantic barred spiral galaxy whose diameter ranges somewhere between 100,000 to 120,000 light years. And let me tell you, one light year equals 9.461 trillion kilometers (5.878625 trillion miles)!
