Unknown Lifeform Made Desert Structures Over A Million Years Ago, Should We Bring Extinct Species Back From The Dead? And Much More This Week






![This astronomical image shows thousands of galaxies across the black expanse of space. The closest thousand or so galaxies belong to the Perseus Cluster. The most prominent members of the cluster are visible in the centre of the image and appear as large galaxies with haloes around them in yellow/white, comparable to streetlamps in a foggy night. The background of this image is scattered with a hundred thousand more distant galaxies of different shapes, ranging in colour from white to yellow to red. Most galaxies are so far away they appear as single points of light. The more distant a galaxy is, the redder it appears.]](https://assets.iflscience.com/assets/articleNo/78554/aImg/82887/perseus-cluster-m.jpg)
