The main differences between the two is that a brown dwarf is a failed main sequence star which due to its inadequate mass, is unable to convert hydrogen to helium whereas a black dwarf is the stellar remnant of a white dwarf (which itself is a remnant of a dead star) when it goes completely … Read more
The universe is filled with a plethora of different-sized stars, the biggest of which we term “hypergiants.” These stars dwarf our Sun, which seems tiny when compared to the size and mass of these colossal entities. And these hypergiants possess some truly strange characteristics. Continue reading to answer all your questions about these “monsters” of … Read more
Quasars are active galactic nuclei that can be found in the accretion disc of supermassive black holes, propelling jet particles angled towards and generating light more luminous than everything in the known universe. On the other hand red giants are the penultimate phase in a stars life where they bloat up exponentially in preparation for … Read more
The hot, fiery atmosphere of the Sun creates an array of remarkable and intriguing features. Two of these are solar prominences and solar flares, but while the former is an unthreatening loop of plasma, the latter is a dangerous burst of energy that has the potential to affect life on Earth. Continue reading to find … Read more
Black holes form when matter is condensed so densely only a dark disc that allows no light to escape remains whereas magnetars form when a large star that dies is unable to become a black hole. Magnetars are essentially the strongest form of a neutron star producing magnetic fields stronger than most in the cosmos, … Read more
Red dwarfs are the smallest and coolest kind of true stars, able to sustain nuclear fusion of normal hydrogen in their cores. Brown dwarfs, on the other hand, are substellar objects that lack the mass needed to fuse regular hydrogen, instead briefly burning deuterium (heavy hydrogen). This fundamental difference is why brown dwarfs are often … Read more
The main difference between a white dwarf and the Sun is that the Sun is still an active star in its main sequence star phase that is stil able to convert hydrogen to helium via nuclear fusion whereas, white dwarfs are the dead remnants of small to medium sized stars (like the Sun) that are … Read more
Red dwarfs and red giants are both red stars that can be spotted in outerspace but, besides their similar color being and temperatures, around 2,200 – 3,200 degrees celsius, both stars are very different. The main differences between the 2 are that red giants are 10000 times bigger than your average red dwarf, have masses … Read more
The main difference between novas and supernovae is that a nova explosion only transpires on the surface of white dwarfs when an abundance of hydrogen is gathered from a companion red giant. In contrast, a supernova is a grandiose explosion brighter than most galaxies that only happens when a larger star or a 1.44 solar … Read more
The Sun and neutron stars are stars at different stages in their life. The sun is an active main sequence star going through the motions of nuclear fusion whilst a neutron star is the remnants of a star much bigger than the Sun after a supernova explosion has occurred. Neutron stars are far dimmer than … Read more
