The galaxies, stars and planets in our universe can look very different when you view them through equipment that sees beyond the visible light our eyes can see.

Male Birds of Paradise have patches of super-black plumage that absorb 99.95 percent of light. New research identified their feathers’ microscopic structures that make them look so very dark.
Diatoms’ tricks may offer new insights that keep solar cell energy running efficiently and robustly throughout their processes.
To understand what is happening in an optical fibre, physicists can mimic a rupture of the flow of grains of light – the photons – thanks to a laser device.
The brain processes colour in more ways that just creating visual images – here’s how.
Whether you’re a night owl or a morning lark, circadian rhythms control just about every aspect of your health.
Georgina, age 5, wants to know why rainbows are round.
Study uses satellite data to add to growing evidence that nighttime light exposure raises risk of breast cancer, with the strongest link among young women.
We’re used to thinking of our eyes detecting light as the foundation of our visual system. But what’s going on in other cells throughout the body that can detect light, too?
Some people think the sky is blue because of sunlight reflected off the ocean and back into the sky. But that’s not the real reason.
We asked five design experts – what’s your favorite product of all time, and why?
Individual light-harvesting protein complexes have a remarkable ability. Light, which is normally effectively harvested, is also used to finely control how much of it should be harvested.
Gaining a better sense of what genes are involved in regulating circadian clocks could put us on a path to find better treatments and therapies to help people adjust to time shifts.
The wrong kind of light can seriously impact your well-being.
A new telescope aims to figure out what became of the universe’s original atoms once the first stars began to shine.
Freezing light in mid-air isn’t just the realm of Star Wars, as new research shows. But what do you do with the light once it’s trapped? One option is to use it to develop new forms of computers.
Flexible light-emitting screens mean you soon won’t need bulbs because your wallpaper – or even your furniture – will light up at the flick of a switch.
Eighty percent of North Americans can no longer see the Milky Way at night. But the problem with light pollution isn’t just about stargazing.
What’s the deal with fat in our foods and drinks? Should we avoid it?
The design of a new chip to detect the twisted nature of light waves could pave the way for next generation of optical communication technologies.
