How to create planet material like alien isolations MM

Hello, and thankyou so much in advance for your time. I’m currently creating planets and would love to gain the knowledge required to create a similar planet dust storm material and “bending light effect” that brightens the edge; one that is seen in alien isolations main menu.
I have searched around and haven’t been able to learn enough to create the swirl while the texture pans, The feeling is its probably some work outside of unreal but honestly unreal surprises me time and again in the hands of a capable developer. again thankyou so much especially if I missed an obvious source.
