But there is one ancient light we can see that we shouldn’t be seeing at all.As part of the James Webb Space Telescope Advanced Deep Extragalactic Survey (JADES), NASA’s James Webb Space Telescope ...

The ability to control the color, or emission wavelength, of light from quantum sources is central to the development of ...

This luminous object, aka a kilonova, shines this brightly because of the emission of large amounts ... Temperatures this ...

Much like the traditional scanning electron microscope (SEM), the field emission scanning electron microscope uses electrons to illuminate a sample, instead of visible light as is used in optical ...

The emission of radiation can be analysed by an ‘emission spectrum’. The different coloured lines show the frequencies emitted by electrons in atoms.

This means that conduction electrons have higher energies inside diamondoids than outside them, which immediately suggests that diamondoids will have excellent electron-emission properties.

Vacuum sealed chamber that contains the field emission gun. A pneumatic valve seals the gun chamber in the event of an accidental vacuum vent. This prevents dust and debris from reaching the tip.
