                           Astronomy Picture of the Day   
      
       Discover the cosmos! Each day a different image or photograph of our   
         fascinating universe is featured, along with a brief explanation   
                       written by a professional astronomer.

                           A Solar Prominence from SOHO   
                   Image Credit: NASA, ESA, SOHO-EIT Consortium   
      
      Explanation: How can gas float above the Sun? Twisted magnetic fields   
      arching from the solar surface can trap ionized gas, suspending it in   
      huge looping structures. These majestic plasma arches are seen as   
      prominences above the solar limb. In 1999, this dramatic and detailed   
      image was recorded by the Extreme ultraviolet Image Telescope (EIT) on   
      board the space-based SOHO observatory in the light emitted by ionized   
      Helium. It shows hot plasma escaping into space as a fiery prominence   
      breaks free from magnetic confinement a hundred thousand kilometers   
      above the Sun. These awesome events bear watching as they can affect   
      communications and power systems over 100 million kilometers away on   
      planet Earth. In late 2020 our Sun passed the solar minimum of its   
      11-year cycle and is now showing increased surface activity.
