Type II Supernova Stars exist in a delicate balance between their owngravityand the fusion engine they ignite. The sheer mass of a star is enough to crush lighter elements together into heavier ones, which rele
A supernova is the explosion of a massive star. There are many different types of supernovae, but they can be broadly separated into two main types: thermonuclear runaway or core-collapse. This first type happens in binary star systems where at least one star is a white dwarf, and they'...
What is a supernova explosion? Star Life Cycles: Stars are formed when parts of dense clouds of interstellar gas (called a nebula) collapse in on their own gravity. The star begins to emerge from this, producing its own energy through the process of nuclear fusion. Stars will continue to ...
This is because the supernova explosion that follows a Wolf-Rayet star enriches the cosmos with material forged by the nuclear furnace at the star’s heart during its lifetime. Advertisement - Continue Reading BelowThis material becomes the building blocks of the next generation of stars, ...
In the case of a planetary nebula, the formation of this deep sky object occurs when a white dwarf star explodes during asupernova. The explosion sends interstellar materials into space that can eventually form into a nebula. Stellar objects that can be called Nebula come in four major classes...
While gravity is always trying to crush a star, what keeps most stars from collapsing is either ongoing fusion, or in cores where fusion has stopped, the fact that you can’t pack the atoms any tighter. In an electron capture supernova, some of the electrons in the oxygen—neon—magnesium...
Compared to the sun, a star whose spectrum peaks in the infrared is: 1. cooler 2. hotter 3. larger Which star is hotter: Vega or Pollux? What type of star is the Sun? What is the temperature of the star Vega? How hot is Rigel?
A supernova is a massive star explosion that occurs when a star burns through its fuel at the end of its lifespan, resulting in a brilliant burst of fiery plasma in vibrant colors radiating with the brightness of a hundred million suns. As described in the journal Nature, the team used ...
Supernova Explosions By scientific standards, the origin of iron is one of the most violent processes imaginable. A type of star known as a red giant begins to turn all of its helium into carbon and oxygen atoms. Those atoms then begin to turn into iron atoms, the heaviest type of atom...
Supernova remnant: The Crab Nebula Exactly as the name says, this is all that remains of a star that has exploded as a supernova. (Image credit: ESO) Dark nebula: Barnard 68 A giant cloud of dust that blocks light from anything beyond it, looking like a "hole in the sky". The ...
