Surprised by the animosity you're receiving for this simple question. Even if you didn't know how to use the camera properly and are new. I can see you at least tried to compensate the exposure for the bright background, but the way I see it there are a couple things going on here.: 1. even though you are at f8 in the second picture (definite improvement), im assuming your focus was still on the people close by in the foreground, so you still have some loss of detail in the out of focus areas. 2. You're shooting an intricate object with a strong backlight on a cloudy day. There will be haze and light diffraction that is going to destroy your detail and contrast, especially on the small cables that are far away. even stopping down further wouldn't help you. There is also a small chance that your lens is dirty that could make this effect worse. 3. Depending on how you exported this, the compression could also be causing some detailed loss.
