A little clever research will wow the studio, and you can dip into your writer's toolbox for the necessary skills. Ask yourself what you're typing to accomplish. If you have trouble at this point, don't worry.
Confusion is a natural part of the process.
Ask someone who knows before you spend a lot of time rooting around. If you need the temperature of outer space, call the observatory. Don't waste hours pouring through astronomy books. It is the most powerful tool you have. Network with people you know and be sure to request referrals.
