Venus, often called Earth's twin, hides extreme conditions and secrets. It is the solar system's hottest planet due to a dense atmosphere. Its atmosphere rotates faster than the planet itself. Venus also rotates backwards and is covered in volcanoes. The atmospheric pressure is immense. It shows phases like the Moon and is the brightest planet in the night sky.

Two massive, unusual structures, dubbed low shear velocity provinces, have been discovered deep beneath Africa. Scientists believe these formations, hundreds of kilometers thick, are composed of ancient oceanic crust that subducted into the mantle millions of years ago. Their unique composition and density cause seismic waves to slow, influencing volcanic activity and heat flow on the surface.
