Unreal Engine 5 UV scaling problem

Question:

I rendered a spherical texture in blender (a planet) and I baked it to a png image then imported that png file into unreal engine to use as a texture in my project, but when I try to use the texture it seems it is improperly scaled to a sphere and doesn't fully cover the sphere:

Here is what it's supposed to look like:

I am relatively new to unreal engine. How do I scale the texture properly or adjust my source file so that the image is properly scaled to the sphere in unreal engine?

Thanks!
