NASA's view of deep space just got sharper.

The James Webb Space Telescope finished its alignment phase after demonstrating it can capture "crisp, well-focused images" with all four of its science instruments, the agency announced Wednesday (April 28).

The milestone, which NASA showcased with some new Webb images, allows the mission team to proceed with science instrument commissioning. The telescope will thus enter a new phase of preparation after several months of mirror and instrument alignments. This next step will take roughly two months, with Webb remaining on track to finish in June if everything goes to plan.

"These images have profoundly changed the way I see the universe," Scott Acton, Webb wavefront sensing and controls scientist at Ball Aerospace, said in the NASA statement. "We are surrounded by a symphony of creation; there are galaxies everywhere. It is my hope that everyone in the world can see them."
