Nova or Supernova. The word "nova" means new, because the star's increase in brightness caused it to be seen for the first time. A nova occurs when a small, dense star feeds on a larger, less dense star so quickly that it bursts. A supernova occurs when a really massive star (this will never happen to the Sun; it's too small) collapses in on itself.

If a star becomes a red gaint when all its hydrogen is used up and later becomes a nebula How can a nebula star form without hydrogen?
The key to this is that NO star uses up ALL of its hydrogen. In fact, they only use up the Hydrogen in their cores, where pressure and temperature are highest. In the case of a red giant, the star is at the stage of burning Helium into Beryllium, Boron and Carbon, which requires much more heat (the heat is "borrowed" from the previous collapsing of the star at the end of the main sequence phase) and continues with a much denser core. When a star expands into a red giant, it blows some of its Hydrogen mass into space. Later, when it simply cannot sustain any fusion reactions in its core, it still contains a considerable amount of hydrogen in the outermost layers, and the subsequent collapse causes a rebound (supernova) that blows about 50% of the original star's mass - most of the hydrogen plus some of the heavier elements into space. When that blown away material collides with a large gas cloud in space which is mostly hydrogen, and compresses that cloud enough that the material can then collapse and form another new star.
What is the of a large compound formed by combining monomers?
The large compound formed by combining monomers is called a polymer. Polymers are made up of repeating units of monomers linked together through chemical bonds. This process is known as polymerization.
What is it called when water soaks up in a paper towel?
Capillary action is the process where water is absorbed and travels through a paper towel due to the interaction of the liquid with the towel's fibers. This phenomenon is driven by the combination of adhesive and cohesive forces.
An electric discharge between two oppositely charged surfaces called what?
An electric discharge between two oppositely charged surfaces is called static electricity. This phenomenon occurs when an excess of electrons is transferred from one surface to another, resulting in a build-up of charge that can discharge in the form of a spark.
What happens when a star burns up all of its hydrogen?
When a star runs out of hydrogen fuel in its core, nuclear fusion slows down and the core contracts while the outer layers expand. The star becomes a red giant as it fuses heavier elements in its shell, until eventually it sheds its outer layers forming a planetary nebula, leaving behind a dense core known as a white dwarf.
What is it called when wind blows sand?
When wind blows sand, it is called a sandstorm. Sandstorms can occur in desert regions where loose sand is easily picked up by strong winds, creating a phenomenon that can reduce visibility and impact the environment.
What is a shell of a star?
The nebula that remains after it blows up.
What will the sun turn into when it blows up?
It will turn into a white dwarf star, after being a red giant star.
What is it called when a star suddenly flares up?
A Nova. The colossal explosion of a very large star at the end of its life is a Supernova.
What star blows up in a super nova explosion?
That will happen to stars that are very massive.
What is the main conflict in star wars trilogy 4?
Luke Skywalker starts Jedi training, and blows up the Death Star.
What do you call a star that blows up because of it's size and heat?
A star that blows up due to its size and heat is called a supernova. This explosive event occurs when a massive star exhausts its nuclear fuel, leading to a collapse of its core followed by a dramatic explosion. Supernovae can outshine entire galaxies for a short period and play a crucial role in dispersing elements into space, contributing to the formation of new stars and planets.
How does a black hole's powerful gravitational pull result in the phenomenon of spitting a star out?
When a star gets too close to a black hole, the black hole's strong gravity can pull the star apart. This process is called "tidal disruption." The star's material gets stretched and heated up, causing it to be ejected in a powerful burst of energy and matter. This phenomenon is known as a "tidal disruption event."
Did the sun blow up?
Why not? It blows after few millions after. That called the death of a star .when all the fuel the sun contains is used up by it, the balance between its gravity and the outward radiation prressure is disrupted (gravity will win) then the sun collapses 3o become a red giant. Thats how sun blows off.
How does Commander data die in Star Trek nemesis?
He blows up the enemy ship with himself on board.
What starts a supernova explosion?
it starts when the star runs out of its supply of gas (i cant remember the name) then the star collapses on its self and then....well blows up
What does a star look like when it dies?
it looks like on tv when a black hole blows up but with a bright light
