Type Ib’s are formed after a large star collapses under its own core gravity where the outer region of the stars hydrogen is stripped away, leaving behind only the second layer of helium. Type Ia’s have a strong silicon absorption line near its maximum luminosity whilst producing no hydrogen at the same time. These are theorised to form after a white dwarf, likely in a binary star system, exploding due to the over consumption of energy from its companion. Type 1’s are then further split into 1 of 3 subcategories, Ia, Ib or Ic.Ī type 1a supernova is the most commonly observed in outer space and acts like a candle light to help us observe distance across the deep unknown.

It can either be via a white dwarf in a binary star system that accumulates too much energy from its companion star causing it to explode or when a larger star runs out of nuclear fuel and collapses under its own gravity, leaving behind the bright and grandiose remnants of this explosion many times brighter than even its own galaxy.Īs stated above supernovae are generally split into 2 types, a type 1 supernova or a type 2. There are two ways that a supernova explosion can form. Supernovae are classified under 2 different types where a type 1 supernova is an explosion that leaves no hydrogen line emissions in the spectra and a type 2 supernova is distinguished where a star 15 times the mass of our sun explodes and does produce hydrogen line emissions.

Therefore, not only are these enigma’s extraordinarily powerful but they can even be used as time capsules to observe how our universe came to be, relatively close to when the theorised big bang occurred. Some light gets drawn in whilst other particles jet out at a tremendous pace, which is how the erratic and powerful light of Quasars form.Īt this moment in time we have discovered roughly 750,000 unique quasars extending across various ages, with the farthest from us roughly 13 billion light years away. Quasars were initially called quasi-stellar radio sources however, this name isn’t entirely consistent with the type of waves quasars generate as only around 10 percent of all quasars that have been discovered produce strong radio waves.Īs for how bright they can be, quasars have been observed to exceed levels that are upwards of 100 times the brightness of the galaxies that hold them.Īlthough not an absolute, many scientists believe these bright objects are formed when light escapes at the edge of a supermassive black hole just before reaching its event horizon. They are also referred to as an active galactic nucleus.

Quasars are the extremely bright celestial objects powered by supermassive black holes, that are found in the center of galaxies. Differences Between A Quasar And A Supernova.Similarities Between A Quasar And A Supernova.Are Quasars More Powerful Than A Supernova?.
