PROBA-2 and Comet “Lovejoy”
The SWAP telescope onboard the Belgian-led satellite PROBA2 has obtained some of the best-ever photographs of a comet passing near the sun. Comet Lovejoy flew through the solar corona, just above the sun’s surface, near midnight on December 16, 2011. This is only the second time ever that a comet has been observed in an extreme-ultraviolet (EUV) solar telescope.
