Sky Survey Detects Cosmic Magnification
The left panel shows a grid of points representing background quasars. The right panel is the same grid after being “gravitationally lensed” by the cluster of galaxies shown in the center of the panel (the magnitude of the effect is exaggerated to make it apparent by eye).

Swift Sees Pinwheel Galaxy, Satellite Fully Operational
This UVOT image of the pinwheel galaxy M101 is a 'false-color' image generated with the near-UV, the blue, and yellow filters, represented by blue, green, and red, respectively. This image shows more light from the central regions of the galaxy, where older, cooler stars dominate the emission.
