March's full "Blood Worm Moon," a phenomenon that makes the moon appear red during a total lunar eclipse, is visible this week for Americans and others in Earth's Western Hemisphere.The full moon reaches peak illumination at 2:55 a.

A total lunar eclipse will be visible on Friday morning as the full moon passes into Earth's shadow.However, sky watchers in Northern Ireland will need to be up early to catch it - and even then, the full "Blood Moon" will remain just out of reach.

A total lunar eclipse will turn this month’s full moon a coppery red that will be visible across the Americas late Thursday into early Friday, but cloud cover from an incoming storm could mean Coloradans won’t get as good of a show.
