The James Webb Space Telescope has transformed how scientists study the universe. With its unmatched ability to detect near-infrared light, it reveals details of distant galaxies once thought ...

THE colour of the light which is emitted from the capillary of a vacuum tube containing pure hydrogen is the familiar vivid, deep pink, the prevailing tint being due to the predominating ...

The light from each star is directed through a prism to produce a spectrum. Each of the spectra has a set of absorption lines created by the presence of hydrogen in the stars' atmospheres.

"We were thrilled when we first observed the strikingly clear methane spectrum in a tiny droplet of liquid hydrogen," said Dr. Hatsuki Otani, who conducted the work while a Ph.D. student in ...

When a gas is very hot, it doesn’t emit all wavelengths of light. Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the ...
