Artificial Solar Eclipse - Proba 3

December 19 , 2024 4 days 119 0
  • With Proba-3, the European Space Agency creates an artificial solar eclipse by bringing two satellites together instead of waiting for natural solar eclipses.
  • This artificial eclipse will be used to study the sun's outer atmosphere, called the corona.
  • The corona is the sun's outermost layer. It still remains one of the most mysterious parts of our star.
  • Although the sun's surface glows at about 5,500°C, the corona's temperature goes as high as 1-3 million°C.
  • Normally, the corona is visible when it is eclipsed totally during a total solar eclipse because the moon blocks some light from the sun.
  • Unfortunately, these natural phenomena occur rarely and for just short periods.
