Solar Experts Detect Waves in Giant Magnetic Holes the Size of the UK

The sun is perhaps the most important yet mysterious star in our solar system. Recently a team of solar scientists led by Professor Robertus von Fay-Siebenburgen, discovered massive waves in giant magnetic holes on the surface of the Sun. The team studied a magnetic region of the Sun much smaller than a sunspot, however its size was still many times greater than the size of the UK.The magnetic hole that they observed, also known as a pore, is able to channel energy generated deep inside the Sun along the magnetic field to the Sun´s upper atmosphere. The magnetic field emerging through the pore is over 1,000 times stronger than the magnetic field of Earth.

The energy being transported is in the form of a very special form of waves, known as `sausage waves´ which the scientists were able to observe using a UK-built solar imager known as ROSA (Rapid Oscillations of the Solar Atmosphere). This is the first direct observation of `sausage waves´ at the solar surface.The experts hope these giant magnetic holes will play an important role in unveiling the longstanding secrets behind solar coronal heating.
