宇宙(universe)之浩渺广博,从我们脚下站着的地球(Earth)、与地球类似的八大行星(eight planet),到恒星(fixed star)太阳和太阳系(Solar System),到银河系(Milky Way Galaxy),再到千万光年之外人类未曾踏足研究的广袤世界……宇宙之中隐藏的谜题太多,在《流浪地球》中,人类与之相比不过沧海一粟。 面对浩如烟海的宇...
The new study, published inNature1, describes a novel way to define where one supercluster ends and another begins. A team led by Brent Tully, an astronomer at the University of Hawaii in Honolulu, charted the motions of galaxies to infer the gravitational landscape of the local Universe, and...

Other ideas point to consistent changes in our planet's orbital cycles, and the fact that our solar system also has a cyclical movement within the Milky Way galaxy roughly every 30 million years. No matter the cause, this study suggests that the data is conclusive: every 27.5 million years,...

The theoretical abundance of habitable worlds among the estimated 200 billion stars of our home galaxy suggests that more powerful telescopes might glimpse the faint signature of far-off planet, proving that, in size and temperature at least, we are not alone in the universe....
