Dwarf planet Ceres, sitting between Mars and Jupiter, might not seem like much, but it once had conditions that could have supported microbial life. Scientists believe that radioactive decay in its core generated enough heat to create a warm internal ocean. This discovery opens up exciting possibilities about the potential for life beyond Earth and challenges our understanding of where life can exist in the universe. Ceres might be more than just a cold, icy rock; it could be a key to unlocking the mysteries of life in space.
