according torecent NASA estimates. The galaxy's visible matter is distributed between its 200 billionstars, their planets and the massive clouds of dust and gas that fill the interstellar space. Astronomers aren't quite sure how many planets are in the Milky Way, given we have only found a ...
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...
The Milky Way is a barred spiral galaxy with a visible diameter between 150,000 and 200,000 light-years. It is estimated to contain 100-400 billion stars and at least that number of planets. The dark matter halo around the Milky Way may span as much as 2 million light years. The ...
这个超大质量黑洞距离太阳系约2.7万光年,质量超过太阳质量的400万倍。 Chinese scientists have contributed to the global effort that captured the world's first image of Sagittarius A, the supermassive black hole at the center of the Mil...
What you’re seeing is a portion of the Milky Way, our home galaxy, which measures 100,000 light-years in diameter. (A light-year is the distance light travels in one year — almost 6 trillion miles, or 9.5 trillion kilometers.) Its core hosts a supermassive black hole — a giant gr...
The Milky Way is 100,000 light-years in diameter, which is small compared to M87, an elliptical galaxy 980,000 light-years in diameter. Bigger still is the galaxy Hercules A, which is 1.5 million light-years across.[5] The central bulge of the Milky Way is about 10,000 light-years ...
At the center of our galaxy lies the supermassive black holeSagittarius A*, often abbreviated Sgr A*. This giant is about 4 million times the mass of the sun and about 14.6 million miles (23.6 million kilometers) in diameter. Around Sgr A* swirls a ring of debris known as anaccretion ...
If I was telling this 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 (...
The MW Galaxy has an approximate diameter of 87,400 light-years, and is 1000 light-years wide across the spiral arms. Our solar system is situated in the Orion Spur, approximately 28,000 light-years from the galactic center. The Great Rift, often referred to as the Dark Rift, is the ...
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...
