This is stunning. The post Astronomers Release Awe-Inspiring Image of What Our Whole Galaxy Looks Like in Radio Waves ...

Did you know that the world around us is filled with different types of light waves ? From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action ...

Researchers at the US National Institute of Standards and Technology (NIST) have expanded by nearly two-thirds the frequency range over which a chip-scale device can generate and measure the ...

Due to the audio medium of radio, we tend to associate radio waves with sound, but they are a type of light. Just like we can ...

New methods of detecting ultra-low frequency gravitational waves can be combined with other, less sensitive measurements to deliver fresh insights into the early development of our universe, according ...

Optical frequency combs are essentially high-tech "rulers" for measuring different colors of light; they're useful for making better atomic clocks and hunting for exoplanets, among other things. Now ...

A recent preprint claims that we may someday be able to create gravitational waves in a lab. Through the use of “twisted” light, we could create powerful, high-frequency waves in a controlled setting.
