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.Understanding what conditions were necessary for life on our planet helps us both trace the origins of life on Earth and guide the search for life on other planets. Until now, however, fully mapping Earth's evolution has been hindered by the simple fact that the young sun wasn't luminous enough to warm Earth.\"Back then, Earth received only about 70 percent of the energy from the sun than it does today,\" said Vladimir Airapetian, lead author of the paper and a solar scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. \"That means Earth should have been an icy ball. Instead, geological evidence says it was a warm globe with liquid water. We call this the Faint Young Sun Paradox.

So, in effect, Hinode has the same perspective as Earth-bound observers since the angle subtended is very small between the Earth and Hinode relative to the moon. However, Hinode's unique orbit has the spacecraft sweaping through the area occulted by the Sun once per orbit, and did so 4 separate times.An annular eclipse occurs when the moon, slightly more distant from Earth than on average, moves directly between Earth and the Sun, thus appearing slightly smaller to observers' eyes; the effect is a bright ring around the silhouette of the moon. || ", "hits": 21 }, { "id": 3595, "url": "https://svs.gsfc.nasa.gov/3595/", "result_type": "Visualization", "release_date": "2009-07-27T00:00:00-04:00", "title": "Sentinels of the Heliosphere", "description": "Heliophysics is a term to describe the study of the Sun, its atmosphere or the heliosphere, and the planets within it as a system.
