Answer

Nicolaus Copernicus was an astronomer who discovered a heliocentric system, that the planets orbit around the Sun; that Earth is a planet which, besides orbiting the Sun annually, also turns once daily on its own axis; and that very slow changes in the direction of this axis account for the precession of the equinoxes

in other words he discovered  that the sun was stationary in the center of the universe and the earth revolved around it.

The heliocentric model was generally rejected by the ancient philosophers for three main reasons: If the Earth is rotating about its axis, and orbiting around the Sun, then the Earth must be in motion. However, we cannot ``feel'' this motion. Nor does this motion give rise to any obvious observational consequences

Brahe showed irregularities in the Moon's orbit and discovered a new star in the Cassiopeia formation. Brahe invented many instruments such as the Tyconian Quadrant which were widely copied and led to the invention of improved observational equipment

The New Star. Tycho made his first significant discovery on November 11, 1572. Observing the night sky from an uncle's home, Tycho was amazed to see a new light brighter than Venus in the sky

could not figure out who some challenges they faced

He did not accept the heliocentric theory

He vehemently rejected the Copernican model because he had no sense that the earth moved and, more importantly, he could not detect parallax in his observations. He proposed a variant in which the earth is fixed, the moon and sun orbit it, and all the other planets orbit the sun.

Hope this helped :)

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
