NASA Facts: Hinode

Solar flares are sudden releases of energy on the solar surface lasting several minutes to a few hours. They occur when magnetic fields on the sun's surface get tangled and 'reconnect,' causing nearby plasma to become superheated.

    Using new information from Hinode, an international mission to study the sun, scientists have found that the dim areas at the edges of active regions may hold the key to understanding how the sun converts vast amounts of energy from its surface into the solar wind. Understanding the origin of solar wind will improve our forecast of space weather and help astrophysicists understand the nature of stellar wind blowing from the surfaces of many other stars.

Overview: Hinode - Mission to the Sun

    Hinode is an international mission to study our nearest star, the sun. To accomplish this, the Hinode mission includes a suite of three science instruments -- the Solar Optical Telescope, X-ray Telescope and Extreme Ultraviolet Imaging Spectrometer.

    Together, these instruments will study the generation, transport, and dissipation of magnetic energy from the photosphere to the corona and will record how energy stored in the sun's magnetic field is released, either gradually or violently, as the field rises into the sun’s outer atmosphere. > Read more
