As Heidelberg scientist Dr. Camilla
Hansen searches for the origin of elements, discovers that silver came to be
during the explosion of special types of starts. These starts are different
from the ones which form gold. We found this out by measuring high-mass stars
with some help.
Other elements like hydrogen, helium
and lithium came to this planet a little bit after the explosion Any other
heavier elements came to be later on the inside of the stars or during star outbursts,
each age group of stars pitched in to add chemical elements to the planet.
A
star can’t create a huge amount of elements in the same time. The amount of
elements a star can create during its life relies on its mass the most. At the end of a stars life, the star
is 10 times the size of our sun explode creating different elements, some
heavier some lighter which are made from the explosion. Silver and gold can
also appear in this way however depending on the weight of the star.
When more than one star of the same
weight blows up, the proportion of the elements which are created from the
explosion are exactly the same.
“The investigations by Dr. Hansen
and her associated scientists have now demonstrated that the amount of silver
in the stars measured is completely independent of the amounts of other heavy
elements like gold. “ This shows that silver is formed in a completely different
way as gold. The scientists explain that silver can’t have appeared in the same
time as gold. The stars they cam from must be a different weights.
I choose this current event again because it is about what we are learning now. Also because I didn't know that elements came from stars. I found that very interesting. Also that different types of stars with different masses create different elements.
