text: LONDON, ENGLAND - JANUARY 10: First full moon of the decade: Wolf moon, rises over London - seen from Richmond Park, UK, England on the 10th January 2020. Skywatchers have been treated to the first full moon of 2020 - known as a &quot;wolf moon&quot; - at the same time as a lunar eclipse. Those gazing up at the skies on Friday, weather permitting, would have seen a penumbral lunar eclipse, which happens when the moon passes through the Earth's shadow.
