Sierra Negra Volcano is situated almost 14000 feet above the sea level in Central Mexico. Next to the flanks of it a giant field of water is existing (which is almost equalling to three hundred water tanks). This is called as the High Altitude Cherenkov Gamma Ray Observatory (HAWC) and is aimed at helping the scientists to measure particles with high energy from the space. These particles are called cosmic rays and they are seen as racing towards the earth at an extreme high pace. These rays are also called as space messengers, as they are believed to carry and bring information across the space. Sometimes information is received from even billions of light years before. Similar to the studies carried out by astronauts, scientists also employ different strategies to study and understand the behaviour of these cosmic rays. The different elements or properties of these rays are studied closely such as the trajectory, radiation, velocity, radiation, energy and mass. It helps them to understand the universe in a better way along with the processes that are involved in it. Cosmic rays can also be employed by scientists to find answers to the problems and queries related to the galaxy as well as the universe as a whole. It is not really possible to understand them just by making use of visual clues.
Cosmic rays are not just messengers or information carriers, but are and cause a high amount of radiation which is extremely harmful to the human body as such. That is also the reason why the earth’s atmosphere acts like a shield protecting the whole population from these radiation. However the astronauts, in the space are unguarded and lack any form of protection. A deep understanding of these cosmic rays would also help and identify a method through which they could be protected.
