English: Larger Dark Matter Particle Size Illustration In this view, the particles (people) are bigger than the other illustration. It is shown that as the size of the people grows, they are forced to scatter farther out into Times Square using this analogy. If this were the case in the universe, then astronomers would expect that dark matter would be spread out over a larger area than if the particles were smaller in size. |

Metadata
This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.
Image title | Using Chandra's image and spectrum of this distant galaxy cluster, scientists were able to determine the mass and the distribution of the dark matter in the cluster. They found that the dark matter mass is about 4 times that of normal matter, and the relative percentage of dark matter increases toward the center of the cluster. These precise measurements of the increase of dark matter toward the center of the cluster make it possible to set limits on the rate at which the dark matter particles collide with each other in the cluster. Such information will allow scientists to better determine the nature of dark matter, which is thought to be the most common form of matter in the universe. |
