This “selfie” was created using a specialized pupil imaging lens inside of the NIRCam instrument that was designed to take images of the primary mirror segments instead of images of space. This configuration is not used during scientific operations and is used strictly for engineering and alignment purposes. In this case, the bright segment was pointed at a bright star, while the others aren’t currently in the same alignment. This image gave an early indication of the primary mirror alignment to the instrument.

NASA has released both the first image captured by the James Webb Space Telescope and even a selfie snapped by one of the telescope's cameras.

This is an artist’s concept of a glow surrounding a drone at Mars during flight. The glow, exaggerated for visibility, might happen if the drone’s spinning rotor blades generate an electric field that causes electric currents to flow in the Martian air around the craft. Although the currents generated by the drone in the atmosphere are small, they might be large enough to cause the air around the blades and other parts of the craft to glow a blue-purple color.

Future Mars helicopter flights could make the air glow blue
