Conclusion

Abstract

Space astronomy is still in the exploratory stage. The data obtained — whether pertaining to the Sun or to distant galaxies — often provide the analyst only with orders of magnitude. But this has already been enough to modify a number of opinions concerning these well-known objects. On the other hand, extension of the observations to very short wavelengths has enabled us to discover and study new objects, previously unknown. What riches may we not expect from the gain in pointing accuracy and refined photometry that space astronomy will bring, in comparison with what has already been done with ground-based telescopes? It is thus undeniable that a modern astronomer no longer has the right to ignore the potential of extraterrestrial laboratories, any more than a space astronomer can disregard the data accumulated at ground-based observatories.* New techniques can and do help us, not only to solve old problems and to refine known solutions, but also to state the old problems in a new way, and to formulate new problems. When astronomy became experimental, it gave us the pride of a poor man’s demiurge. But in becoming extra-terrestrial, it teaches us on the contrary a little more detachment; it teaches us to reject one more anthropomorphism, that of the sky… up above the roof.
