NASA said Thursday that the alignment of the James Webb Space Telescope (JWST) is now complete. 

In a release, the administration wrote that the observatory has been confirmed to be capable of capturing sharp images with each of its four powerful onboard science instruments.

NASA said the Webb team unanimously agreed that Webb is ready to move forward into science instrument commissioning: its next and final series of preparations.

That process is expected to take about two months before its scientific operations begin in the summer.

In engineering photos shared by NASA, the alignment of JWST across all instruments – capturing its full field of view – can be seen. 

For the test, Webb pointed at part of the Large Magellanic Cloud, a small satellite galaxy of the Milky Way.

The sizes and positions of the images depict the relative arrangement of each of Webb’s instruments in the telescope’s focal plane.

The telescope's three imaging instruments include NIRCam, NIRRISS and MIRI. 

NIIRSPEC is a spectrograph that can take images and Webb's Fine Guidance Sensor tracks guide stars to point the telescope accurately and precisely, with sensors that can take calibration images. 

"These remarkable test images from a successfully aligned telescope demonstrate what people across countries and continents can achieve when there is a bold scientific vision to explore the universe," Lee Feinberg, Webb optical telescope element manager at NASA’s Goddard Space Flight Center, said in a statement.

Webb's mirrors are now directing focused light from space into each instrument, with the quality of each image "diffraction-limited," meaning that the fineness of detail that can be seen is as good as physically possible given the size of the telescope.

The only changes made to the mirrors from this point on will be small, periodic adjustments to the primary mirror segments. 

Notably, some telescope calibration activities remain and – as a part of scientific instrument commissioning – JWST will be instructed to point to different places in the sky where the total amount of solar radiation hitting the observatory will vary to confirm thermal stability when changing targets.

Additionally, ongoing maintenance will monitor the mirror alignment and apply corrections when necessary.

"Now, the Webb team will turn its attention to science instrument commissioning. Each instrument is a highly sophisticated set of detectors equipped with unique lenses, masks, filters and customized equipment that helps it perform the science it was designed to achieve. The specialized characteristics of these instruments will be configured and operated in various combinations during the instrument commissioning phase to fully confirm their readiness for science," NASA wrote. "With the formal conclusion of telescope alignment, key personnel involved with the commissioning of each instrument have arrived at the Mission Operations Center at the Space Telescope Science Institute in Baltimore, and some personnel involved with telescope alignment have concluded their duties."
