New research led by NASA provides a closer look at a nearby star thought to resemble our young sun. The work allows scientists to better understand what our sun may have been like when it was young, and how it may have shaped the atmosphere of our planet and the development of life on Earth.
Many people dream of meeting with a younger version of themselves to exchange advice, identify the origins of their defining traits, and share hopes for the future. At 4.65 billion years old, our sun is a middle-aged star. Scientists are often curious to learn exactly what properties enabled our sun, in its younger years, to support life on nearby Earth.
