I am verifying the answers generated by an automatic system to the following question: where was tycho brahe when he discovered mars
Suggested answer: Tycho Brahe was granted an estate on the island of Hven and the funding to build the Uraniborg , an early research institute , where he built large astronomical instruments and took many careful measurements, and later Stjerneborg , underground, when he discovered that his instruments in the former were not sufficiently steady.
Should I validate this answer?
