The vast region around the Sun extending more than twice as far as Pluto should really now be called the “helio-crescent.”
Now NASA has just announced a new five-year grant to allow the scientists to advanced their breakthrough work and investigate how the sun influences and shapes the solar system. That’s what astronomers thought our solar system was like, its heliosphere extending behind it as it orbits the center of the our Milky Way galaxy. At the edges of the heliosphere is where the solar wind meets the interstellar wind. It casts a magnetic force field around all the planets, deflecting charged particles that would otherwise get into the solar system … and destroy DNA. Tell us more about how the changing gas cloud our solar system is moving through affect life on Earth.
