What else can I help you with?
What produces a star's energy?
The nuclear fusion that goes on within the star.
How is gravity involved in the formation of stars?
Gravity pulls the star in and tries to squeeze it down to a point. Because it pulls all of the atoms of the star in to the middle, gravity speeds them up, giving them energy. Eventually gravity gives enough energy to the atoms that they move fast enough that when they collide, they sometimes stick together and nuclear fusion happens. This is what gives a star its light and what keeps a star from collapsing further.
Which form of measurement used to measure brightness can be defined as the rate at which the star gives off energy?
The form of measurement that can be defined as the rate at which a star gives off energy is luminosity. Luminosity is measured in watts and indicates the total amount of energy emitted by a star per unit time.
What happens to a neutron star that gives it the name pulsar?
the name pulsar is given to a neutron star that rotates
Does The Sun gives off more energy than any other star?
No. Sol is a mediocre star. Not too bright, not too dim. It gives off more energy than some, and less energy than some.
A star-sized object in space that gives off huge amounts of energy is a?
Quasar.
What happens as gravity increases the pressure on the matter within a star?
As gravity increases the pressure within a star, the core becomes more dense and the temperature rises. This increased pressure and temperature can trigger nuclear fusion reactions, where lighter elements like hydrogen fuse into heavier elements like helium, releasing energy in the process. This energy output helps counteract the gravitational force, maintaining the star's stability.
What happens as gravity increase the pressure on the matter within a star?
The Rate of Fusion Increases
What gives a star its energy?
A star gets its energy from nuclear fusion in its core. In this process, hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the form of light and heat. This energy sustains the star and allows it to shine brightly.
What is a supernova and what happens?
A supernova is the catastrophic death of a star, characterized by a massive output of energy.
Will you ever run out of stars?
Yes, unless you call a dead star, that gives off no light at all, a "star". Each star has its lifetime - it will eventually stop producing energy. Also, the material out of which stars are made will eventually be used up.Yes, unless you call a dead star, that gives off no light at all, a "star".

What is a body of gas that gives off tremendous amount of radiant energy in the form of light and heat?
A star is a body of gas that gives off tremendous amounts of radiant energy in the form of light and heat through nuclear fusion reactions in its core.
