artificial suns [Q&A]

Vibha of Poornaprajna PU College asks, can we make an artificial Sun? There are many ways this question can be interpreted. If the question is whether we can produce energy in the same manner that the Sun does, then yes, that is what a thermonuclear fusion bomb is. There are some differences, of course. The […]

Supernova [Q&A]

Krishna of Canara College asks, how do supernovae occur? There are two kinds of Supernovae. One that occurs due to the build-up of accreting matter on the surface of a white dwarf, and another that occurs due to a collapse in the core of a giant star. The former is thought to occur as a […]

the erstwhile solar neutrino problem [Q&A]

Yoshita of Poornaprajna College asks, what is the solar neutrino problem? A byproduct of the nuclear fusion reactions in the core of the Sun are neutrinos. Because neutrinos don’t react with much, they escape from the core as soon as they are formed. The number of neutrinos produced is a very sensitive indicator of the […]

successful planets [Q&A]

Rakshit of Vidyodaya Public School asks, what are failed stars? I am not familiar with the term, but my guess is that it refers to objects that are just below the mass threshold necessary to compress the core sufficiently to set off nuclear fusion. It is the onset of nuclear fusion that marks an object […]

mass lost by the Sun [Q&A]

Tilak of SDM College points out that there is a continuous flow of energy from the Sun, and that needs an expenditure of some mass as a result, and thus the gravitational pull of the Sun should decrease and all the planets should move away from the Sun; is this correct? There is an extremely […]
