A sun grazing comet as witnessed by the ESA/NASA Solar and Heliospheric Observatory, or SOHO, as it dived toward the sun on July 5 and July 6, 2011. SOHO is the overwhelming leader in spotting sungrazers, with almost 3000 spotted to date. SOHO can see the faint light of a comet, because the much brighter light of the sun is blocked by what’s known as a coronograph. Credits: ESA&NASA/SOHO
