Just when scientists thought they knew everything about crystals, a Northwestern University and University of ...

Dark matter affects how stars move within galaxies, how galaxies build up over time, and how everything in the universe is ...

Fraunhofer’s goROBOT3D slashes 3D scanning time for transparent and dark materials from 15 to 1.5 seconds using thermal ...

As this type of matter can only emit, reflect or absorb light very ... is similar—visible light can be scattered or absorbed by the dark matter compact objects, causing stars to appear to ...

Inserting any material into a special maze of mirrors and lenses can make it absorb light perfectly. This approach could be used to detect faint starlight or for charging faraway devices with lasers.

For example, hot objects glow with their own light ... Different atomic elements absorb and emit light at very specific colors (the electrons zipping around the atom’s nucleus can only absorb ...

This episode is about how different objects absorb or reflect light, called albedo. We will use dark things and light things to show how it works. It all comes down to this thing called albedo.

The light pulses bounce off objects and back to the sensor, allowing the system to map the 3D environment it's in. But lidar falls short when objects absorb more of that near-infrared light than ...

We see objects by reflected light. We see colored objects because they absorb and reflect different parts of light. When light hits an object, like a flower or a car, some of the colors are absorbed ...
