About this field

A thousand-galaxy cluster at the Galactic north pole, and the field where astronomers first inferred dark matter from galaxy motions in 1933.

The image above is procedurally generated. Source positions, colours and crowding are derived from the field's galactic latitude and character and from the band's pivot wavelength, and every exposure of a field draws the same sky so dithers line up — but none of it is data from the telescope.
