As frustrating as having an atmosphere can be for physicists, it’s just as bad for astronomers, who have to deal with clouds, atmospheric absorption of certain wavelengths, and other irritations. One ...

Deformable mirror using thermal actuators. Route to DIY adaptive optics for hobbyists? Maybe not, but it is an interesting demonstration project! Shoppers alarmed by what's happening at malls: "Living ...

For astronomers, it’s a magical moment: you’re staring at a monitor, and a blurry image of a cosmological object sharpens up, revealing new details. We call this “closing the loop,” a reference to the ...

Scientists have produced the finest images of the Sun's corona to date. To make these high-resolution images and movies, the team developed a new 'coronal adaptive optics' system that removes blur ...

The 5.4 km free-space quantum communication link between the University of Ottawa and the National Research Council Canada, where real-time atmospheric turbulence measurements were conducted to train ...

In the quest for ultra-secure, long-range quantum communication, two major challenges stand in the way: the unpredictable nature of atmospheric turbulence and the limitations of current optical ...
