If I were you, I wouldn't attempt to form anything spherical by hand; the shape is much too perfect and imperfections are really obvious without spending a lot of time. Instead, you should try looking for hollow plastic spheres that you can modify (i.e. plastic ball bit balls, ping pong balls, etc...).

Off the top of my head, I would try to find three balls:
Two balls that are identical size.
One ball that is slightly smaller.

You would need some small fine files, a craft knife, and maybe a small fine hand saw.

1) Cut a section out of the large ball. This will be the front window.
2) Cut a section out of the same large ball, on the back side. This will be the access hole where you will work from.
3) The image you have shows that there is some thickness to the white shell; you want to represent that properly or the prop will look flimsy. The plastic balls you find will most likely have thin shells. Cut some thickish plastic strips to line the inside of the large ball's window. Use the access hole on the back of ball.
4) Cut a section out of the small ball, fit and glue the section into the large ball from the access hole.
5) Finally, cut a small section from the other large ball and use it to patch up the access hole if you want to hide it.
6) Finish and paint it.

If you manage to find a small ball that is transparent, you could even put LEDs inside the prop and light it up. Use a light pass of blue spray paint on the INSIDE surface of the small ball. Paint the face on with white acrylic paint. It might not even need to be transparent. A blue plastic ball pit ball might be thin enough that lighting it from within will make it glow.
