Two scientists discovered a new type of 'whistler,' an electromagnetic wave that carries a substantial amount of lightning energy to the Earth's magnetosphere.
Two scientists discovered a new type of 'whistler,' an electromagnetic wave that carries a substantial amount of lightning energy to the Earth's magnetosphere.
"We as a society are dependent on space technology," Sonwalkar said."Modern communication and navigation systems, satellites, and spacecraft with astronauts aboard encounter harmful energetic particles of the radiation belts, which can damage electronics and cause cancer. Earth's magnetosphere is a region of space surrounding the planet and created by Earth's magnetic field. It provides a protective barrier that prevents most of the solar wind's particles from reaching the atmosphere and harming life and technology.
They developed a wave propagation model that, when considering specularly reflected whistlers, showed the doubling of lightning energy reaching the magnetosphere. "This implies that specularly reflected whistlers probably carry a greater part of lightning energy to the magnetosphere relative to that carried by magnetospherically reflected whistlers," Sonwalkar said.

Lightning sparked all of life on Earth, say Harvard scientists: 'One of the great unanswered questions'Historically experts have theorized that complex life began on our planet around 635 million years ago, as the first organisms evolved in the primordial ooze. However, experts now say that new evidence challenges that timeline and that complex life could have begun more than a billion years before that.
