how do supernovas help us?

Question

I hear we're all made out of supernova is that true?

Answer 1

A star produces atoms in nuclear atomic chemical fusion or fission reactions.
The lifetime of a star takes fusion:
3x4He > 12 C
4 He + 12 C > 16 O plus 2x12 C > 20 Ne + 4 He
56 Fe = Iron
(4 He + 12 C = 16 O)+(2x12 C = 20 Ne + 4 He)_20 Ne + 4 He + 2x16 O
= 56 Fe
As Iron consists to the sun's sunspots now for a magnetic field or liquid Iron of 5,000*C this gives the impression it is black against an even more hot and brighter gassy nuclear background.
But when the sun begins too end it's life the fusion reaches oxygen and then reaches Iron (Fe) and Beryllium (Be).
As the sun is completely filled with Be and Fe at the core. As metal absorbs energy and nuclear and gas forces out then the absorb from the metal core and as energy is released from the outer layers the star is unstable and is formed as a variable. The outer layers are swapped with the inners and the new outer layers are pushed off and out to a red giant until the core revs and the red giant keeps size for a while until a new process begins and the new inner layers of Oxygen from the old outer layers and the Oxygen keeps the red giant pushed out to size and then the whole star is cast as gas/plasma Iron and the star's power, heat and energy accelerates the star and with Oxygen inside, the explosion is created and a new atom is created, Gold.
The minerals create stars from 116 elementary chemicals.
The stars are made in the nebulae and new stars are made and so are planets. Thus the planets and stars create life from their chemicals and their chemicals come from the supernova.

Answer 2

Supernovas actually help us because when a supernova occurs, heavier elements are produced which in turn coalesce in to another star and solar system such as ours. Our sun is actually 3rd generation star, meaning that all of the matter in our solar system has been through 2 supernovas. We need the heavier elements to be produced in these supernovas in order to have life form on our planet. But..... if there were to be a supernova close to Earth, the radiation emitted by the supernova could actually destroy life on Earth.

Answer 3

Sort of.

The only abundant element in the Universe is the simplest - hydrogen. Its nucleus has just one proton.

More complex atoms are all made by nuclear fusion. This only happens when two nuclei collide with sufficient energy - ie at very high temperatures.

An orindary star in its core can generate high enough temperature to fuse elements up to the size of iron (26 protons).

To create atoms larger than iron requires neutron capture. Only supernovae get hot enough for this to happen (they also create the smaller elements of course). So every element heavier than iron on earth came from a supernova.

Answer 4

Most of elements on earth came from supernovas. Supernovas have high enough energy for thermal reactions like the spontanoeus combustion of oxygen to become gold. I think the elements that are heavier than iron come from outer space. So yea, one of the elements that can only come from supernovas is gold. Sorry, thats as much as i know.

Answer 5

well, stars make everything in the universe(well most of it). the take hydrogen, and then they fuse it with other hydrogen to make other elements. However, even the hottest of stars have limits. They can only make the elements up to iron. That leaves other very important elements such as gold, silver, etc. These elements are created in the immense heat of a supernova. thats how the help us.

Answer 6

Supernovas spread around the basic elements needed for life. If those elements wind up in the right places, they can be the building blocks for new life-forms.

Answer 7

We are a 3rd generation planet. The original suns in the universe were only hydrogen and helium. They had to supernova to create the heavy atoms.

Answer 8

They litter the cosmos with heavier elements that life forms like us need to survive. Like iron, is only created in supernovas.

Answer 9

Not true. We consist of elements heavier than iron. Fusion reactions producing elements heavier than Iron are endothermic. When endothermic reactions become dominant in a star, that star will collapse, and the elements heavier than iron would be found only at the centre. Material ejected from a SN only consists of elements lighter than Iron.

Here's an example: We could observe absorption lines of Iron from SN1987a, but not elements heavier than Iron. SN1987a is not visible anymore, it has completely collapsed.

Also when astronomers classify SNe, no one classifies them based on elements heavier than Fe.

Answer 10

Well .. sorta .. as a star expends its energy one of the things that happens is that lighter elements are converted into heavier elements ... when the dying star explodes it slings this matter out and eventually it again forms itself into new stars .. and planets .. and yes .. us.
