IN 1896 Prof. E. C. Pickering discovered a series of lines in the spectrum of the star ζ Puppis which has been attributed to hydrogen in consequence of numerical relationship to the Balmer series ...

Japan is pushing solar hydrogen into a new phase by teaching its materials to drink in colors of sunlight that used to go to waste. Instead of relying only on the most energetic visible wavelengths, ...

WHILE making experiments on the apparent production of neon and helium during electric discharges, I have noticed an effect which may be of interest to spectroscopists. A powerful oscillatory ...

Hydrogen, the lightest element on the periodic table, is a master of escaping almost any container it's stored in. Its ...

Astrophysicists can now analyze the vast molecular clouds of gas and dust where stars are born more accurately. New research has solved equations of quantum mechanics to describe more precisely the ...

Supernovae are classified primarily based on their spectral characteristics, notably the presence or absence of hydrogen lines, leading to type I (no hydrogen) and type II (hydrogen present) ...

Green hydrogen has long been billed as the clean fuel that could decarbonize heavy industry, shipping, and long‑distance ...

A University of Delaware-led research team reports an advance in the June 1 issue of Science that may help astrophysicists more accurately analyze the vast molecular clouds of gas and dust where stars ...

Hydrogen is considered a key energy source that is becoming increasingly popular in today’s energy-conscious world. It must be in liquid form for both transport and use. At 298 K, molecular hydrogen ...

Twelve colors and counting. The terminology associated with hydrogen—specifically, the use of color descriptors such as green, blue and gray—has become widespread in discussions about renewable energy ...
