What does it mean when a comet racing at about 130,000 miles per hour shows hydrogen signatures unlike anything seen in our ...

Astronomers have now observed the radio emission from the neutral hydrogen gas (HI) in a nearby galaxy. Hydrogen gas emits radio emission in a spectral line at a very specific frequency of 1420 MHz.

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 ...

A research team from the Innovation Academy for Precision Measurement Science and Technology (APM) of the Chinese Academy of ...

Molecular hydrogen spectroscopy continues to provide a critical testing ground for quantum electrodynamics and advanced quantum dynamics. Recent methodological advances, including the use of ...

Antimatter is matter that we don’t encounter very much in everyday life. This form of matter is different to the stuff we see around us. In simple terms, antimatter is matter that carries an opposite ...

High-pressure electron tunneling spectroscopy reveals the presence of a superconducting gap in H₃S and D₃S. Superconductors are special materials that allow electricity to flow without any resistance, ...

Taken from the March 2022 issue of Physics World, where it appeared under the headline "The woman who found hydrogen in the stars". Sidney Perkowitz delves into the work and life of Cecilia ...

JWST has detected rare silane gas in an ancient, oxygen-poor brown dwarf, revealing a key clue to why Jupiter and Saturn hide ...

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) ...

Hydrogenases catalyze the reversible splitting and production of hydrogen gas (H2), using complex catalytic cofactors ...
