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 ...

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.

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 ...

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) ...

Hot, dense and blue: the white dwarf Giclas 29-38. (Courtesy: Sloan Digital Sky Survey) Just as you don’t expect snow while hiking through a hot desert, astronomers never thought they would find ...

Astronomers now understand that water-rich planets can form internally, even close to stars. A new study reveals that ...
