There is a deep connection between some of the largest, most energetic events in the universe and much smaller, weaker ones powered by our own Sun.

The results come from a long observation with NASA’s Chandra X-ray Observatory of Abell 2146, a pair of colliding galaxy clusters located about 2.8 billion light years from Earth.

Galaxy clusters contain hundreds of galaxies and huge amounts of hot gas and dark matter and are among the largest structures in the universe. Collisions between galaxy clusters release enormous amounts of energy unlike anything witnessed since the big bang and provide scientists with physics laboratories that are unavailable here on Earth.

这些结果来自NASA钱德拉X射线天文台Abell 2146的长期观测,Abell 2146是一对距离地球约28亿光年的碰撞星系团。

星系团包含数百个星系、大量的热气体和暗物质,是宇宙中最大的结构之一。 星系团之间的碰撞释放出巨大的能量,这与自大爆炸以来所见的任何情况都不同,并为科学家提供了地球上无法获得的物理实验室。
