NASA’s Webb Reaches Alignment Milestone, Optics Working Successfully

The video discusses the Webb Telescope's high-resolution infrared images and the processes involved in achieving optimal image quality. It covers segment identification, image stacking, and coarse phasing to align mirror segments. The use of mathematical techniques, including Fourier analysis, is explained for correcting alignment errors. The final steps involve checking the alignment across science instruments to ensure optimal telescope performance.

Explain the challenges faced in achieving the alignment of the telescope.
