Ultrathin layers of tungsten diselenide have potential applications in opto-electronics and quantum technologies. Researchers have now explored how this material interacts with light in the presence ...

This month, we’ll talk about the relationship between a star’s spectral class and its color. But first, I have a question for you: Which constellation has the most stars of spectral class K9? The ...

Stellar spectral types originally followed alphabetical order. But as astronomers observed more stars and obtained more detailed spectra, they consolidated some categories and reordered the remaining ...
