He explained that if the mass of the axion is about 1 electronvolt (eV)/c 2 (where "c" is the speed of light), then those emitted photons are in the infrared wavelength range, and JWST could see them.

The origin of highest-energy gamma radiation in the nearby radio galaxy Centaurus A could now be localised for the first time ...

An electronvolt is a unit of energy close to that of visible light, so Fermi will catch photons with energies thousands to hundreds of billions of times greater than those we see with our eyes (1 keV ...

"Finding dark matter would unlock an entirely new chapter in our understanding of the universe." As the hunt for dark matter, the universe's most common yet most mysterious "stuff," continues ...
