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 differences between the Sun and Jupiter is that the former goes through nuclear fusion, which allows it to create light, is roughly 10 times the width of Jupiter, is hotter and far heavier than Jupiter, weighing roughly 1000 times more than the gas giant. Both celestial objects are similar in how they are … Read more
A blazar is in essence a quasar that is pointing directly towards Earth, ejecting different radio waves and even gravitational waves towards us, whereas a black hole, particularly supermassive black holes are what power blazars to shine as bright as they do and eject said particles towards Earth. For a more thorough breakdown of what … 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 main differences between spiral and irregular galaxies would include their shapes. The former has a spiral shape and the latter has no discernable shape, spiral galaxies are larger than the Milky Way roughly 5 – 10 times that of your average irregular galaxy and that spiral galaxies make up 60% of all galaxies in … Read more
Quasars and Blazars are one in the same as the latter is simply a subcategory of a quasar. The main thing that differentiates them is the direction at which they point where blazars specifically propel jet particles in the direction of Earth whereas your average quasar’s jet particles are only slightly angled towards Earth. Although the … 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
The main differences between elliptical and irregular galaxies is that elliptical galaxies have a discernable elongated disc like shape whereas irregular galaxies have no discernable shape, elliptical galaxies are up to 1 million light years in size whilst irregular galaxies are 20,000 light years and that elliptical galaxies are the older of the 2 galaxy … Read more
