“Certain astronomers have suggested that the whole phenomenon of novae is due to collapse of the star, and that the energy released in the explosion was produced by compression within. They argue that the nova is a stage in the star’s evolution, the outburst marking one last splurge before it settles down to enjoy a lengthy old age.
The second outburst of T Coronae, however, clearly proves that the collapse theory is wrong.”
It is true that the nova on T Coronae Borealis which is a recurrent nova was not due to gravitational collapse of the star. However the other supernova they talk about, “Tycho’s Star“, is actually a type Ia supernova and was caused by the collapse of a white dwarf.
When Suns Explode
Ours seems sturdy, but bursting stars reveal illness of others.
By DONALD H. MENZEL
Professor of Astrophysics, Harvard University AN EXPLODING star is not news. Dozens of stars blow up each year, increasing: their brilliance 10,000 times or more. Most of them, however, are extremely faint before the outburst, and even at peak brightness are not visible to the naked eye. Really bright objects are rare. But when a star bursts twice in a century-that is astronomical news! It gives us significant scientific information about such stars.

There is a lot of really interesting, important science on this one page. We have cosmic expansion, nuclear fission, Kaluza–Klein theory, proto-computing, the advancement of fluoroscopy, an incorrect model of planetary formation, and um… a way to identify criminals by their sinuses.

TO ATTEMPT ATOMIC DISINTEGRATION BY MAGNETS
BY the use of atomic protons, or nuclei of hydrogen atoms, Drs. Ernest O. Lawrence and M. Stanley Livingston, of the University of California, expect to bombard atoms of other substances and, by breaking up their nuclei, to achieve transmutation, or conversion of one metal into another.
