This image shows a smoothed reconstruction of the total matter distribution in the COSMOS field based on telescope data. The color coding indicates the distance of the foreground mass concentrations, as inferred from gravitational lensing distortions. Structures shown in white, blue and green are typically closer to us than those indicated in orange and red. Click on the picture for a larger version. |
