Can 'scientifically-minded' individuals lead substance-filled lives?
This depends on your definition of 'substance'.

Is it possible to believe that there is 'purpose' in life while being a 'scientifically-minded' person?
Absolutely. In my case, my 'scientifically-minded' reasoning has led me to choose my purposes in life. The default purpose for every one, of course, is to be used as a bad example for others.

Like, if you believe in the big bang, evolution, etc., is it still possible to believe that there is 'purpose' in life?
Yes. Religionists are inclined to believe in determinism or 'predestination', while science-minded people are more inclined to believe in free will. Thus, people are free to choose their purpose. Of course, they must also have the ability to realize this purpose.

I've been wondering this for a long time now, and it's been bothering me lately. I've been 'tinkering around' with astronomy for a while now, and it's hard to decide whether or not there can possibly be substance in life. It's got me quite scared to be honest with you.
You're a little vague on your concept of 'substance'. If you mean 'wealth' then professional astronomy may not be for you. If you mean 'fulfilment' then it depends on what you make of your choices. And if you mean 'spiritual enlightenment' then you'd be better off entering a monastery. As for fear...
"I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain." -- Frank Herbert, "Dune" - Bene Gesserit Litany Against Fear
