Deformable mirror using thermal actuators. Route to DIY adaptive optics for hobbyists? Maybe not, but it is an interesting ...

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 ...

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 ...

SANTA CRUZ, CA–Adaptive optics technology can remove the blurring effect of the Earth’s atmosphere that has long plagued astronomers, allowing ground-based telescopes to achieve a clarity of vision ...

SANTA CRUZ, CA--The same technology that astronomers are using to sharpen the images from ground-based telescopes is also giving eye specialists better techniques for studying and correcting human ...
