One of the main initiatives that are promoted through this website is offering to both students and the larger audience, a better insight into the exploration of deep space and what this process entails and its outcomes so far. Since it represents the final frontier in terms of space exploration, learning more about the distant boundaries of the universe is the key to understanding more about the origins of matter and the surrounding world as it is known today.
The current, presumed extent of the universe is divided into several sections, but the two most important ones make up the known and unknown universe. The first is also divided into the visible universe and the one that is reachable only through remote sensing techniques. The race for space exploration is being carried out at the outer limit of the visible universe, where all there is to know can only be studied using remote sensing methods, which entails scanning the various light and matter specters using advanced satellites and telescopes.
By using highly sensitive machinery and sensors, scientists have been able to find out more about what is actually happening in the distant universe, by analyzing the spectrum of the received wavelengths, be it microwaves, radio waves, visible light or ultraviolet light. The spectrum reaches much farther than that and by adequately converting the spectral signatures, researchers are able to deduce if a distant planet is made out of a particular chemical composition.
Until the bases of interplanetary and even intergalactic flights are set up, the only way which humans are capable of exploring deep space is by relying on state-of-the-art machinery which serves as powerful eyes that can reach out into the most distant galaxies, star-clusters and planetary systems, retrieve information, convert it to interpretable results and yield suitable conclusions.
