These are names for some of the stages of stellar evolution.
- molecular cloud, a stellar nursery where cool clouds of molecular gasses begin collapsing at various point to form protostars.
- stellar nebula, a nebular region of collapsing gas in the process of collapse star formation.
- average star, a star of mass not exceeding 3 solar masses that is on the main sequence of the H&R diagram.
- massive star, a star of 3 solar masses or greater.
- red giant, a star beginning to die, it has run out of hydrogen to burn collapsed enough to ignite helium burning, the resulting large increase in energy release has made its outer shell expand enormously.
- red super giant, a very very large red giant.
- planetary nebula, the cloud of hot gasses surrounding an average star in the process of dieing or that has died. they were initially called planetary nebula because astronomers frequently mistook them for planets before realizing they were really nebular clouds of gas.
- supernova, a massive explosion of a dieing massive star (many times larger than a nova) that completely disrupts a dead star. it is driven by a rebound effect as inwardly collapsing matter of the dead star collides with the surface of the newly formed neutron star. the rebound shockwave blows away most of the infalling gas and drives formation of all elements more massive than nickle and iron. if the supernova is powerful enough it causes the neutron star to implode, becoming a black hole.
- white dwarf, the final visible stage of an average star that has died, after this it cools until it becomes an invisible black dwarf.
- neutron star, one of the final stages of a massive star following a supernova. if the massive star was able to eject enough mass as it died so that the mass of the neutron star formed in the supernova does not exceed 3 solar masses the neutron star is stable. neutron stars consist of nothing but neutrons bound by gravity (not the strong force that holds them together in atomic nuclei).
- black hole, the other of the final stages of a massive star following a supernova. this star failed to eject enough mass as it died to be able to form a stable neutron star. it continues collapsing until its escape velocity exceeds the speed of light. as now even light cannot leave the resulting object is called a black hole. however unlike the cold undetectable black dwarf, black holes because of their enormous mass can be detected by their effects on visible matter surrounding them.
What else can I help you with?
Can a star less massive then the sun become a supernova?
No, stars less massive than the Sun do not have enough mass to undergo a supernova explosion. Instead, they may end their lives as a white dwarf or, if they are even less massive, a planetary nebula. Supernovae are events associated with more massive stars.
Why won't our Sun end in a Supernova explosion?
Our Sun is not massive enough to end in a supernova explosion. When it nears the end of its life, it will shed its outer layers as a planetary nebula and eventually collapse into a white dwarf. Supernova explosions typically occur in massive stars that have exhausted their nuclear fuel and undergo a catastrophic collapse.
What damages can a supernova cause?
A supernova can release massive amounts of energy and radiation, potentially damaging any nearby planets or celestial bodies. The intense radiation from a supernova can strip away a planet's atmosphere and cause disruption to its magnetic field. The shockwave from a nearby supernova could also trigger star formation or disrupt existing planetary systems.
A massive stars terminate in a brilliant explosion called a?
it is Supernova
Does a supernova form a new nebula?
Yes, a supernova can form a new nebula. When a massive star ends its life in a supernova explosion, the explosion can create shockwaves that compress surrounding gas and dust, triggering the formation of a new nebula. This new nebula can eventually give birth to new stars and planetary systems.
What does a supernova provide for the universe?
A supernova provides several important things for the universe. It creates and disperses heavy elements like gold and uranium into space, contributes to the formation of new stars and planetary systems, and releases massive amounts of energy that can influence the surrounding galaxy.
What is a supernova and what happens?
A supernova is the catastrophic death of a star, characterized by a massive output of energy.
Is a supernova a type of galaxy?
No. A supernova is a massive explosion, usually from a dying supermassive star.
Where does a supernova fit into a star's lifecycle?
A supernova occurs at the end of a massive star's life cycle.
What type of supernova will Betelgeuse be?
Betelgeuse is expected to end its life in a supernova explosion, likely as a Type II supernova due to its massive size and age. This type of supernova occurs when a massive star exhausts its nuclear fuel and collapses under its own gravity.
Huge explosion that forms a nebula?
A huge explosion, such as a supernova, can release massive amounts of energy and matter into space. As the expanding debris cools and interacts with surrounding gas, it can form a nebula - a large cloud of dust and gas. Over time, this nebula may give rise to new stars and planetary systems.
Will our sun become a red giant then will it become a supernova then a black hole?
No, our sun is not destined to become a supernova and/or a black hole. It will become a red giant, but it is not massive enough to cross the threshold and become a candidate for a fate like either of those last two.
