地球可能被毛状暗物质包围着
The solar system might be a lot hairier than we thought.
This illustration shows Earth surrounded by theoretical filaments of dark matter called “hairs.”
Dark matter is an invisible, mysterious substance that makes up about 27 percent of all matter and energy in the universe. The regular matter, which makes up everything we can see around us, is only 5 percent of the universe. The rest is dark energy, a strange phenomenon associated with the acceleration of our expanding universe.
The data on hairy dark matter is based on a study by NASA’s Jet Propulsion Laboratory Gary Prézeau that appeared in a 2015 article in the Astrophysical Journal.

太阳系可能比我们想象的要毛茸茸的多。
这幅插图显示，地球被理论上称为“毛发”的暗物质细丝所包围。
暗物质是一种不可见的神秘物质，约占宇宙所有物质和能量的27%。构成我们周围所能看到的一切的常规物质，只占宇宙的5%。剩下的是暗能量，这是一种与我们膨胀的宇宙加速有关的奇怪现象。
关于有毛暗物质的数据是基于NASA喷气推进实验室加里·普雷佐（GaryPrézeau）的一项研究得出的，该研究发表在2015年的《天体物理学杂志》上。
