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.
Exposure
Pointing
Band
H-band; a core survey filter.

All products in this field →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.
