An important technique for discovering and characterizing planets beyond our solar system relies upon measurement of weak Doppler shifts in the spectra of host stars induced by the influence of ...

Researchers developed a new type of spectral shaper that can shape the spectrum of 10,000 lines of light from a laser frequency comb. The image shows the spatial light modulator they used with a 2D ...

A set of five gas discharge tubes are arranged such that when they are touched with a Tesla coil, their characteristically colored emission spectra are seen. The Tesla coil can burn your skin on ...
