What Is a Supernova? Simply Explained A supernova is the most spectacular kind of explosion in the universe — a dying star releasing an unimaginable amount of energy. #supernova #star #physics #space #astrophysics #science #universe | Academic Avengers

"Supernova: A stellar death that sparks new beginnings! When a star reaches the end of its life, it undergoes a dramatic collapse, resulting in one of the most luminous events in the universe. These explosions scatter elements across space, fueling the cycle of star formation and creating the very matter we are made of.

A star exploded – and for the first time, we got a good look inside. When a massive star 2.2 billion light-years away reached the end of its life and exploded in a brilliant burst of light, astronomers analyzing the debris didn’t see the usual outer layers of hydrogen, helium, or oxygen. They saw silicon. Sulfur. Argon. Elements that normally lie buried deep inside a star’s core. This wasn’t supposed to be possible. According to stellar models, massive stars are built like onions.

Supernova supernova is a powerful and luminous stellar explosion. This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion. The original object, called theprogenitor, either collapses to a neutron staror black hole, or is completely destroyed. The peak optical luminosity of a supernova can be comparable to that of an entire galaxy before fading over several weeks or months. | Free AstroScience
