How long does it take for a massive star's core to become iron from silicon?
from silicon to iron, about a day.
Does Jupiter have an iron core?
Scientists believe that Jupiter's core may contain both iron and nickel. The core also contains water, ammonia and methane ice layers.
How does gravity effect stellar evolution?
Gravity effects stellar evolution by pulling down force on the stars while they are forming. Mass will determine how long the star stays alive and burning.
What is inside of all of the planets?
Different for each planet. Earth has a core of molten iron and rock. The Moon appears to be solid to the core, having cooled a long time ago. Venus is probably still molten at the core; heck the SURFACE is nearly molten. Mars is smaller and further away, so may have a small molten core or may be solid iron and rock. The gas giant planets may have small rocky cores, or may be gasses compressed to metallic solids by the immense pressure. We will have to do more studies to find out.
How long does a star stay as a stellar nebula?
until the date is 420 and then the star moves to earth to get baked

What stars originated in the same stellar nursery as Sol?
We don't know. The Sun has been around for a long time, and has orbited the galactic core a number of times, while its orbit around the core has undergone many chaotic perturbations. Stars born from the same stellar nursery might be right around the corner, or they might be at the opposite side of the galaxy. Currently, we can't even tell which stellar nursery the Sun was born from, or whether it still exists.
Why is iron special in stellar evolution?
Energy is liberated through fusion reactions, producing heavier and heavier elements. There are two transient elements heavier than iron which are produced by standard stellar nucleosynthesis, but these are short lived and decay into lighter elements. Iron is the heaviest element forged in the heart of a star via standard stellar evolution. All elements heavier than iron are the byproduct of a supernova, wherein atomic nuclei are smashed together with such force energy is consumed in the nuclear reaction. This is why there tends to be an abundance of stable isotopes as light as iron, but elements heavier than iron are much more rare. Lead is an exception to this general rule as it is the end product of a long radioisotope decay sequence.
How many km is the Earth's core?
The Earth has a liquid core containg iron (Fe) and nickel (Ni).
Will the sun become a white dwarf neutron star or a black hole?
The long-term fate of the sun according to current theories in stellar evolution, is to become a white dwarf. It lacks the mass to further collapse into a neutron star or black hole.
How is earths core apparently similar to some iron meteorites?
The Earth's core contains a lot of iron and nickel like a meteorite, it's why we have a magnetosphere which protects us from the sun's solar radiation (most of it)....As long as the core remains molten and in motion it'll continue to generate magnetism, otherwise we'll end up like Mars.
How can you turn a piece of iron into a magnet?
To turn a piece of iron into a temporary magnet, wind a coil of (insulated) copper wire around it and run a DC current through the wire. The iron will become the core an electromagnet -- the one you just constructed. As long as direct current flows through the coil, the iron core will attract ferromagnetic materials.jkghyjy Wrap many coils of lacquered copper wire round an iron nail. When electricity is sent through the coils, the nail becomes magnetised. The iron is an electromagnet as long as the power is on. When a piece of iron is brought near the magnet it also becomes a temporary magnet.
How long did it take for wtc1 to collapse after strike?
It took around an hour for it to collapse.
How long did it take for the South Tower to collapse?
It took 102 Minutes for the North Tower to Collapse.
What do scientist believe causes earths magnetic field?
The center core of the earth is solid iron surrounded by molten iron. The center is solid due to the great pressure and the spinning mass of molten iron around the solid iron core creates the electrodynamic effect that causes Earths magnetism. Our moon has little or no magnetic field because its core has long since cooled.
What would happen if you dig to the inner core?
If someone was to dig into the inner core, the planet would be hurdled towards the sun and doomed to destruction in less than 3 seconds.totally legit.You can't just dig to the inner core, since any hole that you dig would collapse long before it gets that far, however, I can imagine that with sufficient technological support, you could dig a hole and install a very durable and heat resistant pipe to keep the hole open. If you could get all the way to the inner core you would have access to a virtually unlimited source of valuable nickel and iron. It would be a fantastic mining opportunity.
