Swift‘s first light!

NASA posted Swift’s first-light images today, along with a press release about a slew of bursts that the BAT (Burst Alert Telescope — Swift’s GRB watchdog) observed during instrument calibration last month.

The image is the BAT’s “first light” gamma-ray image showing Cygnus X-1 (top) and Cygnus X-3 (bottom).
