The collective umbrella term for all scientific disciplines (xenobiology, xenochemistry, xenoarcheology, etc.) that are fundamentally reconfigured to study phenomena of unequivocally extraterrestrial origin. These are not Earth sciences applied elsewhere; they are entirely new frameworks built from the ground up after the paradigm-shattering discovery of "The Other." Their core principle is that Earth is just one data point, and our terrestrial rules may be the exception, not the universal law.
Example: Once we confirm the discovery of a complex alien ecosystem, biology splits into Biology (the study of Earth life) and Xenobiology (the study of that life). The same would happen for geology, chemistry, and physics. The Xenosciences represent the colossal, revolutionary academic project that would begin the day after First Contact, requiring us to rewrite all the textbooks.
