[Ben Bartlett] recently got engaged, and the proposal had a unique bit of help in the form of a 3D-printed hexagonal mirror array, whose mirrors are angled just right to spell out a message with the ...

The James Webb Space Telescope (JWST) generated considerable excitement when its first test images were released earlier this year: they proved that the instrument was working and helped its engineers ...

The James Webb Space Telescope has reached a new milestone: “Fine-phasing” calibration is now complete, which means all 18 hexagonal submirrors are acting as a single unit, and are now focused and ...

The James Webb Space Telescope hit another milestone this week; NASA announced that the $10 billion observatory's 18 hexagonal mirror segments and its secondary mirror have been fully deployed. "Just ...

We won’t be seeing any stunning images of space from the James Webb Space Telescope just yet, as the telescope is still undergoing the months-long process of aligning its mirrors. However, there are ...

The James Webb Space Telescope finished the first major stage in its long process of aligning the observatory's 18-segmented primary mirror. A single star that the observatory looked at was ...

It takes two unique types of mirrors working together to see farther back in time and space than ever before, and engineers at NASA’s Goddard Space Flight Center have just received one of each type.

Jul. 13—The James Webb Space Telescope looks farther back in time than any telescope thus far — more than 13 billion years, nearly to the beginning of the universe. The images provided by Webb would ...
