Over the last few decades, satellites and rockets have been launched into space, littering the cosmos(宇宙) as they go. It's estimated there are now millions of thrown-away pieces of metal and other materials in orbit-everything from old rocket pieces to accidentally dropped astronaut tools, ...
Observations made in space have contributed to our understanding of black holes and the expansion of the universe. 8 Universe It includes everything from the smallest particles to the largest galactic structures, and even the empty space between them.

What are some possible shapes of our universe? The universe's shape in multidimensional space Fate of the universe Additional resources While it's relatively straightforward to identify the shapes of planets, moons and galaxies, it's more complex to measure the shape of the universe. In ...
The shape of space plays a significant role in the future of the cosmos, determining whether the Universe will expand indefinitely or contract in a “Big Crunch.” There are three commonly discussed shapes of space: flat, spherical, and hyperbolic or “saddle.” Each shape has distinct ...
“The poem and views are both magnificent as well as healing. If everyone could enjoy the same sight, a lot of pain in the world would be ‘dissipated’,” one user comments. As the first Italian female astronaut in space, Cristoforetti carried out her first space mission on Nov 23, ...
The probability of winning is tiny. So in the game of planetary formation, forming a solar system with our Earth is like winning the lottery.获胜的可能性很小。所以在行星形成的游戏中，太阳系中诞生了地球就像中了彩票一样。Scientists are only now fitting together all the various chapters of this...
In the chemical reactor there's a vacuum very close to that of interstellar space. And the temperature is minus 200° Celsius.在化学反应堆中有一个非常接近星际空间的真空空间。温度是- 200摄氏度。We made the ice, we can see a bit here, a sort of growth on the edge of the window. The ...
