Solar Prominence Near Sun’s North Pole

Solar Prominence Near Sun’s North Pole:

Scientists recently observed a large prominence near Sun’s north pole

  • Large, loop-like structures on the edge of the solar disk sometimes stand out brightly against the dark background of space.
  • These enormous structures are called solar prominences.
  • Prominences are anchored to the Sun’s surface in the photosphere, and extend outwards into the Sun’s hot outer atmosphere, called the corona.
  • They are much cooler and denser than the surrounding plasma in the Sun’s corona.
  • Prominences are shaped by the Sun’s complex magnetic field, often forming loops with each end anchored to the Sun’s surface.
  • Prominences are enormous, extending out for many thousands of kilometers.
  • They can last for several days or up to several months.
  • Some prominences erupt and break apart, giving rise to coronal mass ejections (CMEs).
  • Coronal Mass Ejections (CMEs) are large expulsions of plasma and magnetic field from the Sun’s corona that propagates outward into interplanetary space.
  • The blast of a CME carries about a billion tons of material out from the Sun at very high speeds of hundreds of kilometers per second.
