First Solar Eclipse Recorded From Moon

dazza101 writes "For the first time ever, we have witnessed a solar eclipse from the moon. On 10 February 2009 Japan's Kaguya lunar orbiter captured the sight of the Earth eclipsing the sun. The spacecraft also recorded this video showing the Earth surrounded by a glowing ring and briefly forming the classic diamond ring that often occurs during a solar eclipse, as seen from down here on Earth."

    It's even better than a solar eclipse as seen from earth because the earth's atmosphere diffracts light from the sun, causing a ring of light to appear around the planet. Very cool.

      This is indeed one of the most amazing photos I have seen. Yeah, nebula are pretty, galaxies are neato and we all like those quirky things that radio telescopes find, but this is our planet. Somewhere on that black circle with the little white halo... somewhere on that is where I am. My house, my work, my friends. I might have been asleep when that was taken, I might have beer right here at work.

      And while I was doing all that, someone took a few amazing photos. Kudos to them!

      That's not diffraction. The irregular surface of the moon partially blocks the sunlight during a solar eclipse, producing an effect called Bailey's beads. The drama of this effect is helped considerably by the rough equivalence of the sun and moon's angular size as seen from Earth.
      By comparison, on the moon the Earth is approximately three times the angular size of the Sun, so the illumination of the rim only occurs because of atmospheric diffraction. This diffraction of sunlight is also responsible for the reddish light one sees during a lunar eclipse.

  4. "Pudenda"?! 'scuse me? by Anonymous Coward · · Score: 3, Funny

    FTFA: "A pudendal lunar eclipse is a phenomenon in which the Sun, Earth and Moon line up in tandem, hence the Moon is in the Earth's pudenda, or, when you look from the Moon, the Sun is partially covered by the Earth (partial eclipse.) During this phenomenon, the volume of sunlight to the Moon decreases, and the Moon's surface looks darker when you look at the Moon from the Earth. The KAGUYA, which circles around the Moon on its polar orbit, can witness this phenomenon only twice a year at most, thus it was very valuable to capture the moving images of the phenomenon from the KAGUYA."

  7. Terran Eclipse? by clintp · · Score: 4, Informative

    During a total solar eclipse (from the Earth's perspective), the ring of light around the moon is from the sun's photosphere showing around the edges of the moon.

    The ring around the earth in the solar eclipse (from the Moon's perspective) is from the light refracting from the atmosphere. I'd think the Earth's relative size would be far too large for an effect like Baily's Beads to be seen from the moon.

    Or am I missing something?

    1. Re:Terran Eclipse? by mbone · · Score: 4, Informative

      You are correct. The Moon's angular size is close enough to the Sun's that some eclipses are annular (the Moon is too far away to cover the Sun). Even during a total eclipse, you can see the bright inner corona (not the photosphere - that's what makes it total).

      For lunar eclipses, the Earth will generally completely cover the Sun, inner corona and all. However, refraction through the Earth's atmosphere lights up the Lunar landscape, (i.e., the light of every Sun rise and Sun set going on everywhere on Earth). This light - the depth of the eclipse - has been used to infer global atmospheric conditions over historical time.
