"Blue Moon" Appears in Sky Saturday Night

Posted by Hemos on from the blue-moon-you-saw-me-standing-alone dept.

ArbiterOne writes "Tonight a rare spectacle can be seen: the second full moon in a month, which is sometimes called the "blue moon", according to CNN. Don't be disappointed if it isn't actually blue, though; the blueness is caused by increased density of smoke or ash in the air, such as after a volcanic eruption."

  1. How rare? by lildogie · · Score: 4, Insightful

    "A rare spectacle" that happens more often than U.S. Presidential elections. I guess that makes the elections a rarer spectacle.

  2. Science? by bokmann · · Score: 3, Insightful

    This falls under science? This is solely an artifact of our time measuring system. The moon is full every 28 days, but months are slightly longer than that. If a full moon is early enough in the month, it will be full twice.

  3. So what? by codexus · · Score: 4, Insightful

    This is just a calendar coincidence not any kind of astronomical event. And in fact it happens quite often. So really, there is nothing special to see here. Was that really worth mentioning on slashdot?
