Though still only in the prototype stage, this flat lens could one day be used on space telescopes, and perhaps even on ...

For the first time, a flat telescope lens has been produced that represents colors accurately, offering a way to make less bulky lenses that could be sent into space cheaply. The first telescopes used ...

ESA's Euclid mission is exploring the "dark universe." The space telescope's latest images offer fascinating new insights.

The thicker and heavier the lens, the more it bends the light, and the stronger the magnification. For everyday cameras and backyard telescopes, lens thickness isn’t a huge problem. But when ...

The European Space Agency has released the first batch of large-scale images from the Euclid space telescope, which ...

For centuries, telescopes have relied on curved lenses and mirrors to capture images of the cosmos. While effective, these traditional optical elements are heavy and bulky. Large observatories and ...

For centuries, telescopes have relied on curved lenses and mirrors to observe the Universe. A team of researchers has recently developed a flat, lightweight lens capable of capturing precise color ...
