A vertical matrix X-ray detector for multi-energy discrimination

There are three types of cone cells in the retina that are called L-cones (sensitive to red light), M-cones (sensitive to green light), and S-cones (sensitive to blue light). The coordinated response of cone cells to visible ...

Is Europe entering a golden age of astronomy?

Groundbreaking discoveries about gravitational waves, black holes, cosmic rays, neutrinos and other areas of cutting-edge astronomy may soon become more frequent due to the convergence of two major communities of astronomers ...

Image: Hubble uncovers a burst of star formation

NGC 4666 takes center stage in this image from the NASA/ESA Hubble Space Telescope. This majestic spiral galaxy lies about 80 million light-years away in the constellation Virgo and is undergoing a particularly intense episode ...

Image: Hubble snaps speedy star jets

This striking image features a relatively rare celestial phenomenon known as a Herbig-Haro object. This particular object, named HH111, was imaged by the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 (WFC3).

Color-changing coatings triggered by temperature changes

The changing of color can influence our perception of objects, be used to warn us against dangers or hazards, or help to conserve energy. Ph.D. candidate Weixin Zhang has developed organic "photonic" coatings that change ...

New NASA data sheds light on climate models

Have you ever worn a dark T-shirt on a sunny day and felt the fabric warm in the sun's rays? Most of us know dark colors absorb sunlight and light colors reflect it—but did you know this doesn't work the same way in the ...

Thin, large-area device converts infrared light into images

Seeing through smog and fog. Mapping out a person's blood vessels while monitoring heart rate at the same time—without touching the person's skin. Seeing through silicon wafers to inspect the quality and composition of ...
