There are only two ways you can see something in the world. The first is to have an object that emits light. The light from this object then enters your eye and your brain interprets it. Examples ...

Visible light is the portion of the electromagnetic spectrum that can be detected by the human eye.

It can record 3D images of moving objects and, importantly, function as a microscope to capture holographic movies even through light-scattering materials like a mouse skull.

An invisibility cloak hides objects in visible light For the first time, invisibility rugs can hide large objects. So it goes, the impossible history of invisibility cloaks.

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 they ...

No doubt most of us have heard that black and other dark objects are more absorbant and white and light objects are more reflective, but let’s start out by clarifying just what’s being ...

Astronomers posed over the past decade that dark comets, or objects that resemble asteroids but move like comets, may exist. Now, scientists have found a total of 14 of them.

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light.

Research published in ACS Applied Materials & Interfaces describes a highly reflective black paint that could help these cars see dark objects and make autonomous driving safer.
