Key Takeaways:

The James Webb Space Telescope has successfully sent its initial images to Earth, including a "selfie" of its primary mirrors and an 18-segment mosaic of a single star.
These early images are crucial for the ongoing calibration and alignment of the telescope's 18 primary mirror segments, a process that is currently proceeding successfully.
Once fully cooled and calibrated, the telescope is expected to begin sending back higher-quality scientific images by this summer.

The James Webb Space Telescope sent its first two images back to Earth—a single star and a kind of outer-space selfie.

Friday morning, NASA released the two images as part of the telescope’s calibration process. The black-and-white photo serves as a selfie of Webb’s primary mirrors. In its reflection, the secondary mirror is visible in the center segment. Since Webb’s decades-long development racked up a bill of $10 billion, the telescope surely holds the unofficial title for the world’s most expensive selfie taken.
