Venus Unclouded: Scientists Release Unique Photos of Earth's Sister Planet

Researchers used the world's largest fully steerable radio telescope, known as the Robert C. Byrd Green Bank Telescope (GBT), as well as a powerful radar transmitter at the Arecibo Observatory, located in Puerto Rico, to make detailed pictures of the planet's surface, featuring mountains, ridges and volcanoes.

Astronomers used both sets of photos to study how the planet's surface changed over time. They look for the signs of dynamic geological processes in the hope of broadening our understanding of Venus' geological history and its current state.
