Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to ...

We’re all taught that water is clear, so why does the ocean look so strikingly blue when we’re staring out […] ...

Quantum sensors have become important tools in low-energy particle physics. Michael Doser explores opportunities to exploit ...

That’s because dark colors absorb light, whereas light colors — like that of a pristine, white ice sheet — are reflective. If ice gets covered in dark particles, it melts faster. “2023 was a record ...

Using colored grout is a simple way to make those backsplashes and tiled kitchen walls look a little more interesting without ...

What color is moonlight typically, and what other colors can moonlight look like from our perspective on Earth?

In this state, photons behave like particles and can reflect and emit light with an intensity and order that it appears almost ‘brighter than white’—not only in brightness, but in how precisely the ...

The combo of the two can be difficult to take in with the naked eye. Did you know that beaches with white quartz sand also tend to have prettier water? Sun rays reflect light off the underwater quartz ...

The result is a mixture of steam and white or light gray smoke that contrasts sharply with the dark, carbon-rich black smoke.

The final ingredient, pine rosin, produces thick white smoke when heated—releasing tiny droplets and light-colored ash that appear whitish.

These mysterious whitish-gray glows in the northern lights might be cousins of the mauve light streak known as STEVE.
