About this field

A dense window toward the Galactic centre, imaged every fifteen minutes during six-week seasons. Microlensing here is expected to yield thousands of cold exoplanets, including free-floating worlds bound to no star at all.

Product status

A pre-flight simulation product. Generated on the ground to build and test the calibration pipeline before launch — useful for developing analysis code, but it is synthetic, not sky.

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.
