Students discover bright lensed galaxy in the early universe

The night sky is a natural time machine, used by cosmologists to explore the origins and evolution of the universe. Reaching into the depths of the past, a class of undergraduate students at the University of Chicago sought ...

3-D-printed smart gel changes shape when exposed to light

Inspired by the color-changing skin of cuttlefish, octopuses and squids, Rutgers engineers have created a 3-D-printed smart gel that changes shape when exposed to light, becomes "artificial muscle" and may lead to new military ...

Image: Hubble sees a 'molten ring'

The narrow galaxy elegantly curving around its spherical companion in this image is a fantastic example of a truly strange and very rare phenomenon. This image, taken with the NASA/ESA Hubble Space Telescope, depicts GAL-CLUS-022058s, ...

Rogue planets: hunting the galaxy's most mysterious worlds

Most known planets orbit a star. These planets, including Earth, benefit from the star's warmth and light. And it is the light emitted from these stars which makes it possible for us to see them. But there are also "invisible" ...

Detection of gravitational wave 'lensing' could be some way off

Gravitational wave scientists looking for evidence of "lensing," in which the faintest gravitational wave signals become amplified, are unlikely to make these detections in the near future according to new analysis by scientists ...

Engineers produce a fisheye lens that's completely flat

To capture panoramic views in a single shot, photographers typically use fisheye lenses—ultra-wide-angle lenses made from multiple pieces of curved glass, which distort incoming light to produce wide, bubble-like images. ...

Anti-reflective coating inspired by fly eyes

The eyes of many insects, including the fruit fly, are covered by a thin, transparent coating made up of tiny protuberances with anti-reflective, anti-adhesive properties. An article published in the journal Nature reveals ...
