Applications of Astronomy and space sciences could be easily found in every single day of your life. Islam encouraged and still stimulates its believers to explore the space which was created by God.
“Do they not look at the sky above them, how We have built it and adorned it, and there are no rifts in it.” (Surat Qaf: 50:6).
“(God) created the heavens without any pillars that you can see…” (Surat Luqman: 31:10).
Moreover, “God is the One Who raised the heavens without any pillars that you can see, then He firmly established Himself on the throne and He subjected the sun and moon . . .” (Surat Ar-Ra`d: 13:2).
