what if we went to other planets and saw a fascinating creature? can we take its picture for research purposes?
It is not lawful to take photograph of living beings though for the purpose of research, you can take the photographs of nonliving things. There is stern warning in hadith for those who make the picture of living beings. Hence it cannot be allowed except in severe compulsion.
Allah (Subhana Wa Ta’ala) knows Best
