这张3D地图的获得，得益于HST和XMM-NEWTON的数据，提供了直观的象网般大型分布的暗物质的影象，一个不可见却是占宇宙质量很多的物质。
地图展示了细丝状暗物质的松散网状结构，逐渐地在引力残酷的牵拉下不断坍缩，并最后变成一个团块。
盒子的3轴分别对应着太空的位置（赤经和赤纬）和距离地球的长度（从左到右依次增加）（通过宇宙学红移来测量）。记录下暗物质的凝集是如何变的更加明确，在立体地图上从右到左，从早期宇宙到近代宇宙。
This three-dimensional map, obtained thanks to HST and XMM-Newton data, offers a first look at the web-like large-scale distribution of dark matter, an invisible form of matter that accounts for most of the Universe's mass.
The map reveals a loose network of dark matter filaments, gradually collapsing under the relentless pull of gravity, and growing clumpier over time.
The three axes of the box correspond to sky position (in right ascension and declination), and distance from the Earth increasing from left to right (as measured by cos
