Changes to the Sun

There have also been some recent dramatic changes to the sun. The Ulysses spacecraft sent by NASA to measure the magnetic field of the sun found the magnetic fields of the poles enormously diminished. The magnetic poles of the sun usually reverse at the end of an eleven-year sunspot cycle. At the end of the most recent cycle, the poles only moved to the sun’s equator and did not completely invert. This behavior alters everything that was previously believed about the sun’s magnetic field. Effectively, the sun no longer has a single north or south magnetic pole; instead, it has four poles located in the equatorial regions.
