Caption: The Magellanic Clouds and the Auxiliary Telescopes at
the Paranal Observatory in the Atacama Desert in Chile. Only 6 of the
9 newly discovered satellites are present in this image. The other
three are just outside the field of view. The insets show images of
the three most visible objects (Eridanus 1, Horologium 1 and Pictoris
1) and are 13x13 arcminutes on the sky (or 3000x3000 DECam pixels).

Caption: The Magellanic Clouds and the stream of neutral
hydrogen. The insets show the image of the largest satellite
discovered (Eridanus 2) as well as the smallest one (Indus 1). The
insets are 13x13 arcminutes on the sky (or 3000x3000 DECam pixels) for
Eridanus 2 and 6.5x6.5 arcminutes (or 1500x1500 DECam pixels) for
Indus 1. |
