Students will compare observations of visible light to develop wavelength ranges for different colors. Virtual option if you do not have a spectrometer If you do not have access to a visible ...

You can make the case that none of them are in true color. But then again, if they were, they’d be unable to reveal the true nature of objects emitting or reflecting various kinds of otherwise ...

Scientists have developed a pioneering technology capable of omnidirectional wavelength tuning, which promises to revolutionize a myriad of tunable photonic applications. Structural colors ...

The colors that wind up there are longer wavelengths of light — red, orange, yellow — which withstood the journey through "a thick slice of Earth's atmosphere," NASA said. Shorter wavelengths ...

This first light, as it's called, shows that all of the spacecraft's systems are working just as expected. "Based on the ...

NASA's SPHEREx (short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) has ...

A brand new NASA space observatory, SPHEREx, has taken its first test images a few weeks after its launch on March 11, and ...
