Researchers mapped a far-infrared landscape brimming with nearly 2,000 galaxies. There may be "hidden galaxies" lurking just out of sight.

A simple tweak to the usual setup is all that is needed to enhance a spectroscopy technique that uses waves in the terahertz ...

The terahertz region of the spectrum, which is often called the far infrared, lies between the mid-infrared and microwave regions. It has remained largely unexplored until recently because ...

Well, those wavelengths lie in the infrared region of the electromagnetic spectrum — and on April 1, NASA announced its brand new infrared space telescope, SPHEREx, has officially opened its ...

Physicists have created a compact laser that emits extremely bright, short pulses of light in a useful but difficult-to-achieve wavelength range, packing the performance of larger photonic devices ...

Short-wave infrared radiation (SWIR) is roughly the part of the electromagnetic spectrum between 1.4 μm – 3 μm, or 100 THz – 214 THz. This places it between visible light and microwaves ...
