How Does Studying Comets Help Science Hi,moncler outlet online Nintend, my name is Eylene Pirez and I'm an astrophysicist and this is how does studying comets help science. So comets are a really,moncler outlet online Great A, really important part of our solar system. They've been around since the beginning of the solar system 4.6 billion years ago and I will kind of briefly explain what are comets and what are they made and I will talk about the importance for science. So a comet is made out of a nucleus and a nucleus is between a hundred meters to 40 kilometers in size. Now this is generally gases and ice and sort of embedded rock. It also can be found carbon dioxide, methane ahs been found in them, ethane has been found in it, oxygen has been found in it. A lot of type of amino acids and so forth. So it has a lot of trapped gases and each one is different than the other so they're each comet is unique. The other one is that the other part of the comet is the coma and the coma is like the atmosphere of the, it's just the cloud of gas surrounding the nucleus. Now the comets also have the two types of tails. It has the dust tail and the ion tail and these two are only this little only once they orbit the sun which is another important fact about comets. Comets actually have stable order to round the sun and their orbits can range from a short period which is less than 200 years to a long period which is over 200 years. Now why are they important. Why do we want to look at this comet. Well the reason is that this composition can give you an insight of what was the actual abundance of elements at the beginning of the solar system because they been around for 4.6 billion years, they actually have the primordial gases, the primordial composition the solar system as it was 4.6 billion years ago so it gives us a clue of what was the solar system really made out of. Now another important thing is that they contain,woolrich outlet International, many of them contain the building blocks of life that can be responsible for bringing water into planets for creating lift. As you have collisions with these comets they can actually bring in some of the important gases or some of the important elements that can constitute, that can be responsible for the creation of life. A really important discovery was the Wild 2 comet and the Wild 2 had these amino acids that have been though to have been responsible for the reason of life here on Earth so there's a possibility that we had some impacts with comets and comets brought all these building blocks that are responsible for life.
