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 ...

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 ...

One of the persistent mysteries about our Universe is the extreme imbalance between matter and antimatter. Antimatter and matter were both generated during the Big Bang, but the Universe is now ...

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.

Coherent anti-Stokes Raman scattering (CARS) spectra are reported for flavin adenine dinucleotide (FAD) and glucose oxidase (β -D-glucose:oxygen 1-oxidoreductase; EC 1.1.3.4), in resonance with the ...

We can now report success in observing this line. A micro-wave radiometer, built especially for the purpose, consists mainly of a double superheterodyne receiver with pass band of 17 kc., the band ...
