These images are a composite of separate exposures acquired by the WFC3/IR instrument on the Hubble Space Telescope. Several filters were used to sample narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Cyan: F125W Orange: F164N

Bat Shadow Schematic
This illustration shows a fledgling star surrounded by a warped, saddle-shaped disk with two peaks and two dips. A planet embedded in the disk, inclined to the disk's plane, may be causing the warping. As the disk rotates around the young star, it is thought to block the light...
Flapping Bat Shadow Video
This video shows the "flapping" of the Bat Shadow's wings. This motion is most likely caused by the shadow of a saddle-shaped disk, with two peaks and two dips. The disk must also be flared, like bell-bottom pants or a trumpet. The shadow is so large—about 200 times the length...
