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 first recognized that supernovae come in multiple flavors more than 60 years ago. In 1941, German physicist Rudolph Minkowski proposed a two-level scheme based on the absence (type I) or ...

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 ...

THE recent investigation by Dr. Merton of the effect of an admixture of helium on the intensity distribution in the hydrogen spectrum appears to have given a very strong clue towards the elucidation ...

A group of researchers who are antimatter enthusiasts has claimed big success in measuring antimatter atom on the optical spectrum by triggering hope that the breakthrough can fast track ...
