Black Rain is falling on Tehran and it doesn't stop there. Oily, toxic, and flammable. Roads turn to ice rinks, planes fall from the sky, your tap runs brown, and crops die in the ground.

What If You Explored Every Kepler Planet?
Some planets might look promising from a distance, but stepping onto them could turn them into the most dangerous places in the universe. In this episode, we explore the extreme worlds discovered by the Kepler Space Telescope and imagine what would happen if a human explorer tried to survive on them. From crushing gravity and toxic atmospheres to molten lava oceans and massive gas giants, these alien planets highlight the hostility of the universe. What would it be like to land on Kepler-10b, a blazing lava world hotter than most metals can survive? Could anyone breathe on Kepler-62f, a planet with an atmosphere loaded with carbon dioxide? And what happens if you fall into the endless storms of the gas giant Kepler-16b? Even worlds that seem potentially habitable, like Kepler-22b or Kepler-452b, may hide deadly conditions that render survival nearly impossible. Ever wondered what would actually happen?
