Faint X-Ray Emission along 8 Different Directions in the Perseus Galaxy Cluster (image) NASA/Goddard Space Flight Center Share Print E-Mail Caption Suzaku explored faint X-ray emission along eight different directions in the Perseus Galaxy Cluster, shown here in false color. Bluer colors indicate fainter X-ray emission. The dashed circle marks the cluster's effective boundary, where new gas is now entering, and is 2.7 degrees wide. Credit NASA/ISAS/DSS/O.
