Materials that bend light in unnatural ways are often touted as the path to futuristic technologies such as cloaking devices and super-powered lenses. But such materials are hard to make, but scientists have now...
So-called “fire rainbows” are neither on fire nor are they rainbows, but they sure are stunning. They are technically known as iridescent clouds, a relatively rare phenomenon caused by clouds of water droplets of...
(multimedia) The brightest planets in the solar system are converging for a beautiful sunrise sky show in early July.
(multimedia) During a powerful solar blast on March 7, NASA’s Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun. The discovery heralds Fermi’s new role as a...
Spritzing a sunscreen ingredient into the stratosphere could help counteract the effects of global warming, according to scientists behind an ambitious new geoengineering project. The plan involves using high-altitude balloons to disperse millions of tons...
(multimedia) A tiny bubble of air is manipulated through a saline solution, directed by heat produced by infrared laser light. Its creators see this most simple of robots as a potentially ground-breaking tool for...
(multimedia) (CBS News) Is there a cure for blindness near? Ask the scientists in the U.K. who have restored useful vision in two men who had previously been totally blind. During clinical trials at...
The mystery surrounding the source of the highest-energy particles known in the Universe has grown deeper. The particles, known as cosmic rays, can show up with energies a million times higher than the biggest...
For the first time, astronomers have glimpsed reflections of light from a “supernova impostor”—the so-called Great Eruption of the star system Eta Carinae, which was seen from Earth more than 150 years ago. The...
The mysteries of the universe are as vast and wide as existence itself. Throughout history, mankind has searched and struggled to find the answers tucked away inside the universe and everything we see around...
