Again, Ames, what are you setting out to learn? The positions of the stars? Their brightness and even their composition? Or their supposed origins?
Only the last can be spiritually damaging, and even that is not a given if all you want to find out is how we understand the way Hashem created them. The Torah is not meant to give us the technical details of creation, only to make it clear Who created the world and for what purpose. Parshas Bereishis is hard enough to listen to on Simchas Torah; would you like to hear a series of chemical reactions as well? (The only chemical reaction that matters on Simchas Torah is the reaction of ethanol with various human cell structures….)
The problem is only found in cases of brainwashing by those who use their findings to deny Hashem and the authenticity of the Torah.
