The James Webb Space Telescope is a massive collaborative project between NASA, the ESA, and the CSA. After decades of work, the observatory was ready for launch, and did so on Christmas of last year. That then began a months long commissioning process. The telescope needed time to get to its final location, Lagrange point 2, and then time for the main mirror and instruments to cool down.<\/p>\n

The 18 different mirror segments also needed to be aligned and focused. The very first calibration image showed 18 smudgy versions of one star. These needed to be aligned, stacked, and focused. By late February, the images were stacked, but the teams still had to work on fine phasing to get a single, focused image. <\/p>\n

The teams have come a long way since then, with that fine phasing allowing them to bring that first calibration star, HD 84406, into focus back in March.<\/p>\n
