Solar Storms May Have Been Key to Life on Earth
Our sun’s adolescence was stormy—and new evidence shows that these tempests may have been just the key to seeding life as we know it.
Some 4 billion years ago, the sun shone with only about three-quarters the brightness we see today, but its surface roiled with giant eruptions spewing enormous amounts of solar material and radiation out into space. These powerful solar explosions may have provided the crucial energy needed to warm Earth, despite the sun’s faintness. The eruptions also may have furnished the energy needed to turn simple molecules into the complex molecules such as RNA and DNA that were necessary for life. The research was published in Nature Geoscience on May 23, 2016, by a team of scientists from NASA. (by
