Planet Earth is made up of four overlapping subsystems that contain all of world’s land masses, water sources, living organisms, and gases. These four subsystems are known as spheres. Geographers break down the Earth’s systems into four spheres that make up the world’s air (atmosphere),...
After decades of searching, astronomers have uncovered some of the strongest evidence yet of exoplanets orbiting Barnard’s Star, the nearest single star system to Earth. The four planets are classified as sub-Earths because each one is about 19% to 34% the mass of Earth, according to new r...
