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.

    Images from NASA-funded telescopes aboard a Japanese satellite have shed new light about the sun's magnetic field and the origins of solar wind. Data from the Hinode satellite shows that magnetic waves play a critical role in driving the solar wind into space at speeds of almost 1 million miles per hour. Better understanding of the solar wind may lead to more accurate prediction of damaging radiation waves before they reach satellites.

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
