Diary Entry 4: 21/08/15
On my final day in the modern world i decided that i would view the modern technologies that helped discover the universe. In this modern day there are organisations that are entirely dedicated to measure, discovering and viewing the cosmos, one of these being NASA.
NASA is a government organisation that envisions reaching for new heights and reveal the unknown so that what the find will benefit all humankind, the way they find these "unknowns" is through methods such as human exploration, imaging of the farthest reaches of the galaxy, measurement of radiation from the sun, etc.

Human exploration is about the focuses on International Space Station operations, development of commercial spaceflight capabilities and human exploration beyond low-Earth orbit allowing first hand experience of low gravity or viewing the vastness of space itself.








Satellites are innovative and extraordinary pieces of technology that are sent to space, these satellites can range from sending signals to different places on different sides of the world, or to view and record the radiation and heat being omitted from the sun the satellites measure the suns radiation means its light intensity. The satellite will collect data on the sun's light output, UV radiation and irradiation. Irradiation is a measure of the amount of light energy incident on a unit area of surface per unit of time. The sun's radiation data collected by the satellite will be much more accurate because the Earth's atmosphere will not interfere. Not only are the results of the measurements much more accurate that measuring it from Earth it also helps enhance the validity of the big bang theory.



One of the most impressing pieces of technology is the Hubble space telescope. With the early developments of the telescope by Galileo it was made possible to view space from Earth giving scientist an improved source of technology to help understand the universe. However back in the day i tinkered around with my own telescope and create my own version of a telescope, my telescope was made with reflecting mirrors rather than refracting lenses like in Galileo's telescopes. A large mirror would capture the image, then a smaller mirror would bounce it into the viewer's eye. Not only does this method produce a clearer image, it also allows for a much smaller telescope design allowing for easier travel.












However, our telescopes compared to the Hubble space telescope were mere toys, planks of wood, antiques. The Hubble space telescope is a powerful telescope able to observe in the near ultraviolet, visible, and near infrared spectra and produce the most detailed images allowing deep view into space and time. Its success is present by the fact that it has made 1.2 million observations since its launch in 1990.
