The Fermi Paradox, named after physicist Enrico Fermi, highlights the contradiction between the high probability estimates for the existence of extraterrestrial civilizations and the lack of evidence or contact with such civilizations. Given the immense size and age of the universe, and the relative ubiquity of the physical and chemical laws that govern life on Earth, many scientists and thinkers have argued that the Milky Way galaxy should be teeming with alien life.
NASA's Kepler exoplanet-hunting space telescope ended its mission in 2018, but its contribution to exoplanet science is ongoing. It generated a huge dataset, one that astronomers are still working through. Researchers found a new candidate exoplanet in Kepler's data named HD 137010 b that's orbiting a Sun-similar star nearly 150 light-years away. The new exoplanet is only slightly larger than Earth, and its orbit is about as long as Earth's.
