Stargazers on nearly one half of the world witnessed a total lunar eclipse overnight, as a rare cosmic lineup caused the moon to turn a shade of red.

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.

On the morning of Friday, March 14 -- the day of the full Worm Moon -- the moon will be 12 degrees above the western horizon as twilight begins at 6:23 a.m. EDT. No planets will be visible at that time, NASA said.
