Compass and scale image of MACS J1149+2223

The large image on the left is dominated by the many galaxies of the massive cluster MACS J1149+2223. Gravitational lensing by the giant cluster brightens the light from a newfound galaxy, known as MACS1149-JD, some 15 times. The upper right shows MACS1149-JD in more detail, and a deeper zoom appears to the lower right. This newfound galaxy is thought to be the most distant galaxy ever observed and opens a window onto the deepest, most remote epochs of cosmic history
