Studying astronomy

Q: "Is astrological study forbidden for us." I mean can we study it just to gain some new knowledge, not meant to use it for fortune telling... Just for getting knowledge about the effect of heavenly bodies on our natural behaviour.

Winning a prize from a bank

Q: I have recently opened a bank account and the bank has a scheme for all its customers where one account number will be chosen in a lucky draw... The account holder will receive some price money.

There is no payment required to be a part of this lucky draw.

My question is, if someone wins the prize money... Is it halaal to use this money?
