Solar activity would not necessarily be fatal if you pop up the atmosphere density a bit to trap and reflect incoming radiation.

In fact, we can imagine a world where life on it is very partial to high frequency radiation and thrives on it. Such a life would simply need to have component elements with greater atomic complexity than just hydrogen, carbon, etc.

Uranium might be a simple element when compared to some which we have not yet discovered. Life is still a mysterious thing which we cannot say only evolves like us.

In fact it is preposterous for us to make any calculations or projections with a test sample of one - us - to base our guesstimates upon.

I will go out on a limb and say that life in some form likely exists in EVERY solar system. Whether this is intelligent life or amazingly ignorant life is all open to interpretation.;-)
