The cluster of galaxies 1E0657-56 has been the subject of intense research in the last few years. This system is remarkably well-suited to addressing outstanding issues in both cosmology and fundamental physics. In this talk I will present the new HST/WFC3 deep data on the Bullet Cluster. Using this ideally placed (in terms of redshift) and accurately focused cosmic telescope we are able to efficiently sample the bright end of the luminosity function of high redshift galaxies. Furthermore, gravitational lensing offers often the only way to confirm their redshifts purely from imaging data, and potentially also allow for (otherwise prohibitive) spectroscopic follow up. With shallower and comparable magnitude limits to UDF and GOODS (respectively), the Bullet Cluster observations, after correcting for magnification, probe deeper into the luminosity function of the high redshift galaxies and paired with deep HST/WFC3 observations will provide us with one of the first peaks at z>7 galaxies.
