Earth’s Building Blocks Came From Within | Science News

Earth’s building blocks may have come from much closer to home than scientists once thought. New research by Paolo Sossi and Dan Bower reveals Earth’s material is almost entirely from the inner Solar System—less than 2% possibly from beyond Jupiter. Using advanced isotope analysis across ten systems, they challenge decades-old assumptions about how water and volatiles arrived here. Jupiter’s gravity likely acted as a barrier, isolating Earth’s formation zone—and may have done the same for Mercury and Venus. This reshapes our understanding of planetary origins and how life’s essential ingredients made it to our planet. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
