Engineering marvel: Sixth mirror cast for Giant Magellan Telescope

The Giant Magellan Telescope announces fabrication of the sixth of seven of the world's largest monolithic mirrors. These mirrors will allow astronomers to see farther into the universe with more detail than any other optical ...

Solar telescope releases first image of a sunspot

The world's largest solar observatory, the U.S. National Science Foundation's Daniel K. Inouye Solar Telescope, just released its first image of a sunspot. Although the telescope is still in the final phases of completion, ...

Scientists solve big limitation of stratospheric balloon payloads

Nearly all photons emitted after the Big Bang are now visible only at far-infrared wavelengths. This includes light from the cold universe of gas and dust from which stars and planets form, as well as faint signals from distant ...

Image: Shape-shifting mirror

This bendable space mirror can have its shape shifted to compensate for manufacturing or alignment errors within orbital telescopes or temperature-driven distortions.

Deployment test of Webb's secondary mirror

The secondary mirror—visible in the top right corner of the image—is among the most important pieces of equipment on the NASA/ESA/CSA James Webb Space Telescope (JWST) and is essential to the success of the mission.

Critical deployment of NASA Webb's secondary mirror a success

In order to do groundbreaking science, NASA's James Webb Space Telescope must first perform an extremely choreographed series of deployments, extensions, and movements that bring the observatory to life shortly after launch. ...
