"How did these form? What are the seeds of these black holes?" In addition, a major enigma of the dark ages is how dark matter — the as-yet unidentified materialmaking up about 85 percent of all matter in the universe — might have influenced the formation of the first galaxies. This...
As the mass of the clump increased so did its gravitational pull, causing it to collapse down to a smaller size and higher density. In this way, the first proto-galaxies were able to form within the first few hundred thousand years of the universe's existence, according to NASA's Goddard...

Mather, the leader of the team at NASA that built the Webb, explains how the telescope will observe the first galaxies to form in the early universe, peer behind clouds of cosmic dust and gas to reveal stars being born and uncover new details about places like Europa and Titan, which ...
根据以下资料，回答6—10题。 以3D打印技术、云计算等为代表的“第三次工业革命”正在以科技推动世界。3D打印设计的计算机和机器人或将成为灵巧的生产工厂，以全新方式进行生产制造。中科院重庆分院近日研发出国内首个3D打印并联机器人。它可完成直径220毫米的物品制造，精密度比较高，1个这样的机器人造价才10...
Our eyes have been drawn away from the heavens to our screens. We no longer look to the sky to forecast the weather, predict the seasons or plant our gardens. Most of us cannot even see the Milky Way. But First Nations Elders of the world still maintain this knowledge, and there is ...
aBut scientists have discovered many other galaxies in the universe. They are a long way away and their light has travelled for many years to reach us. it ishard to understand how large the universe is. 但科学家在宇宙发现了许多其他星系。 他们是长的路,并且他们的光移动许多年到达我们。 它...
the other parts, matter at the perimeter was pulled toward the center. whereas matter in the center, because it was pulled equally from each side, did not move at all, and thus the nebula contracted with the greatest concentration of matter occurring in a central region called the protosun....
