Why does supernova explosions in space be seen but not heard on earth?
Supernova explosions are incredibly bright and release vast amounts of energy, making them visible across great distances in space. However, sound requires a medium, like air or water, to travel through. In the vacuum of space, there are no air molecules to carry sound waves, so while we can see the light from a supernova, we cannot hear it on Earth.
Does gold come from space?
Yes, gold can come from space. Gold is thought to have been formed in supernova explosions billions of years ago and then brought to Earth through meteorite impacts. However, the majority of gold on Earth is thought to have been created through geological processes within the Earth's mantle.
Elements after iron are made how?
In the universe they are initially made in supernova explosions. These then become parts of other stars, planets and celestial bodies. Some are radioactive and decay into daughter elements which are usually after iron.
Where did iron come from?
The element iron was created in massive stars, and then released through supernova explosions. over time, it was bound up in rocky material and helped to form planets.
What are the two primary sources of matter?
The two primary sources of matter are stars and supernova explosions. Stars produce elements through nuclear fusion in their cores, while supernova explosions distribute these elements into space, where they can form new stars and planets.
What stellar event produced elements with atomic masses greater than iron?
Supernova explosions are responsible for producing elements with atomic masses greater than iron through nucleosynthesis processes. During these violent events, heavy elements are forged from lighter elements through rapid fusion reactions.
Where are the heaviest nuclei of all formed?
Elements heavier than iron are formed through the fusion reaction in stars when a supernova occurs. The lighter elements up through iron are formed in "regular" stellar fusion, and this is what powers most stars throughout their lives. A lot of energy is created in the fusion reactions, and this is why stars "burn" the way they do. But after iron, fusion switches from exothermic to endothermic. That means energy must be put into the fusion reaction to create these heavier elements, and only when a super abundance of energy is available, like during the collapse of a star in a supernova, is there sufficient energy to drive those fusion reactions. All the trans-iron elements up through uranium are created in the supernova.
What happened first big bang or supernova?
The Big Bang happened first. It is the beginning of the Universe as we know it - we don't know what happened before that.During the Big Bang, hydrogen and helium were formed; other elements were created later, through nuclear fusion - and some of those were ejected in supernova explosions.
What layer did oxygen form?
Oxygen is thought to have formed in the core of massive stars through nuclear fusion processes, particularly during supernova explosions. However, oxygen can also be produced through various nucleosynthesis processes in different stellar environments.
Why do younger stars have more heavy elements?
Younger stars have more heavy elements because they form from the remnants of older stars that have already produced and dispersed these elements through processes like supernova explosions.
Where are naturally occurring elements manufactured?
Naturally occurring elements are created through nuclear fusion in the cores of stars through a process called nucleosynthesis. These elements are then dispersed into the universe through supernova explosions and stellar winds, eventually forming into planets.
What are majority of the elements made of?
The majority of elements in the universe are made of hydrogen and helium, which are the two lightest and most abundant elements. Other elements are formed through nuclear fusion processes in stars or during supernova explosions.
