Before LEDs and lasers came along, video projectors would shine white light through a rotating color wheel to produce full-color images. But researchers at Dartmouth College and Disney Research Zürich have come up with a more unusual projection approach using prisms and very precise computer-generated black and white…
The science of rainbows: it’s something we’re all taught in grade school. Airborne water droplets act like little prisms, bending and splitting light. Mix enough water and sunshine, and you get a brilliant bow of color.
Better known as an iridescent cloud, a cloudbow is just what it sounds like: A cloud full of rainbows.
We're accustomed to seeing urine as yellow, or, if we're extremely hydrated, clear. That doesn't mean that pee can't have all kinds of colors. Let's explore the biochemistry of making one's pee all the colors of the rainbow.
Check out this amazingly beautiful optical effect — this rainbow-like feature, called a "glory," was recently captured by Europe's Venus Express orbiter. This is the first time the phenomenon, which also happens on Earth, has been imaged on another planet.
This is as joyous as any spiderweb is ever going to look. Either spiders are killing pixies and smearing their colorful blood on their webs (I wouldn't put it past them) or something else is going on here.
The first thing you need to know is this: I wrote "The Unicorn and the Rainbow" on a dare. Which, given that this is the one story in my new erotica collection that everyone remembers and everyone talks about, is a weird beginning. But it's a true story.
Everyone knows you don't get pictures of rainbows this beautiful, without sacrificing a few leprechauns. Like, seriously, at least 100 of the little guys.
Happy hump day, everyone! Here for your enjoyment is a whale, seen off the coast of Nova Scotia, spraying a rainbow out its blowhole. This is clearly a magical whale, and this phenomenon has absolutely nothing to do with tiny water droplets refracting light into the visible color spectrum. Do not doubt the…
Ben Masterton-Smith, recipient of the inaugural RIBA Norman Foster Traveling Scholarship in 2007, visited North Korea for a period of architectural and spatial research.
Here's a rare look at a rainbow over the skies of Ethiopia. Find out how this cloud — known as a "pileus cloud" — brightens the atmosphere.
