What makes a supernova occur in a star's lifecycle?
A supernova occurs in a star's lifecycle when it runs out of fuel and its core collapses, causing a massive explosion.
What is a hydrogen envelope?
A hydrogen envelope refers to the outer layer of a star that primarily consists of hydrogen gas. It is the region where nuclear fusion reactions occur, converting hydrogen into helium and releasing energy in the form of light and heat. The size and properties of the hydrogen envelope can vary depending on the age and mass of the star.
What makes up a star and how does it contribute to its formation and characteristics?
Stars are made up of mostly hydrogen and helium gas, along with trace amounts of other elements. The force of gravity causes these gases to come together and form a star. As the gases compress and heat up, nuclear fusion reactions occur in the star's core, producing energy and light. This energy counteracts the force of gravity, keeping the star stable and allowing it to shine. The size, temperature, and lifespan of a star are determined by its mass and composition.
What is the verb for Phenomena?
The verb form of "phenomena" is "occur" or "happen".
Do radio waves occur naturally in the environment?
Yes, radio waves occur naturally in the environment as a form of electromagnetic radiation.
What does a neutron star form?
A neutron star is what is left behind from some supernovas, which occur when a massive star explodes.
Where would a new star most likely form?
A new star would most likely form in a region of space called a stellar nursery, found within dense interstellar clouds of gas and dust. These clouds provide the necessary materials and conditions for the gravitational collapse of the gas to occur, leading to the birth of a new star.
What reactions occur within the star in the stellar equilibrium?
In the stellar equilibrium, the primary reaction is nuclear fusion, where hydrogen atoms are fused to form helium, releasing energy in the form of light and heat. This process is sustained by the star's gravitational pressure balancing the force of nuclear fusion. Helium fusion into heavier elements can also occur in more massive stars.
What happens in the star core?
The core of a star is located inside the star in a region where the temperature and pressures are sufficient to ignite nuclear fusion, converting atoms of hydrogen into helium, and releasing a tremendous amount of heat.
Where are supernovae?
Supernovae are massive explosions that occur when a star uses up its gas and explodes so they will only occur once a star has died.
Where does nuclear fusion occur in any star?

When does fission occur in a star?
Never, only fusion
What is nature of Mercury?
Mercury do not occur in combine state (i.e. it occur in free state) and in liquid form. It is the only metal who occur in liquid form.

Where does a star form?
Stars form in a nebulae
What can occur after a high mass star explodes?
A supernova resulting in either a neutron star, or a black hole.
How many years does it take to produce a star?
Well its a 2 fold answer really. Firstly the gases that form a star take millions if not billions of years to come together. However when a Protostar is formed, this is not a true star as it produces heat via friction not fusion; once this starts to occur it only take about 100,000 years to go from Protostar to Star.
