Islamic view of space exploration
Question

                As-salam-alaikum
With all this talk of space exploration and "whether there is life" outside 
our beautiful planet, what does the Quran have to say about alien beings? 
Furthermore, should we discover life on another planet, how should we 
react to this new discovery? This may sound as a strange question, but the 
thought is in my belief an interesting one, which brings into question 
science that does not always work side by side with any religion. 
Salams.
Praise be to Allah.
Islam does not prevent man from attempting to explore space and the wonders it 
contains, or from looking at the dominion of Allaah and what He has created in heaven 
and earth, as He has commanded us to do in His Book. But we should pay attention to 
two things:
We should weigh the time, effort and money spent on this purpose against the 
benefits which we expect to gain from it.
Man should first learn how to walk and behave on earth before he tries to go into 
space.
May Allaah bless our Prophet Muhammad.
