Saturday’s Lunar Eclipse Will Include ‘Impossible’ Sight
This year’s second total lunar eclipse on Saturday (Dec. 10) will offer a rare chance to see a strange celestial sight traditionally thought impossible.
The moon passes through the southern part of the Earth’s shadow, with totality beginning at 6:06 a.m. PST and lasting 51 minutes. [Total Eclipse of the Moon (Infographic)]
For most places in the United States and Canada, there will be a chance to observe an unusual effect, one that celestial geometry seems to dictate can’t happen. The little-used name for this effect is a “selenelion” (or “selenehelion”) and occurs when both the sun and the eclipsed moon can be seen at the same time.
But wait! How is this possible? When we have a lunar eclipse, the sun, Earth and moon are in a geometrically straight line in space, with the Earth in the middle. So if the sun is above the horizon, the moon must be below the horizon and completely out of sight (or vice versa).
And indeed, during a lunar eclipse, the sun and moon are exactly 180 degrees apart in the sky; so in a perfect alignment like this (a “syzygy”) such an observation would seem impossible.
But it is atmospheric refraction that makes a selenelion possible.
Atmospheric refraction causes astronomical objects to appear higher in the sky than they are in reality.
For example: when you see the sun sitting on the horizon, it is not there really. It’s actually below the edge of the horizon, but our atmosphere acts like a lens and bends the sun’s image just above the horizon, allowing us to see it.
This effect actually lengthens the amount of daylight for several minutes or more each day; we end up seeing the sun for a few minutes in the morning before it has actually risen and for a few extra minutes in the evening after it actually already has set.
The same holds true with the moon, as well.
As a consequence of this atmospheric trick, for many localities there will be an unusual chance to observe a senelion firsthand with Saturday morning’s shadowy event. There will be a short window of roughly 1-to-6 minutes (depending on your location) when you may be able to simultaneously spot the sun rising in the east-southeast and the eclipsed full moon setting in the west-northwest.
Actually, its not as rare as implied here. In fact, it happens during every lunar eclipse, at all those places on the Earth where it is sunrise or sunset at the time of the eclipse.
alright, it finally looks like a dress. although it only does so thanks to 20 pins. there’s still LOADS to do. i made it way to big around the waist, it still needs boning so it stays up on its own, it’s still too long and the list goes on forever.
but hey, at least it looks a lot like the original?
Especially my boobs are pretty accurate.
Now that’s my kind of cosplay! *whistles*
The Hobbit Behind-the-Scenes Production Video Blog #4
Filming with no less than 48 Red Epic cameras at 48fps in full 5k resolution might sound fantastic, but it hasn’t all been a bed of cotton candy. Two 3D cameras need to be mounted at the same “interocular” (the inch-or-so distance between your eyes) which is impossible given the size of the Epic and its lenses. The team had to hire specialist firm 3ality to build a rig where one camera shoots the action and the other is pointed vertically at a mirror.
The biggest thing that impressed me in this video was the 3D concept art. I just cannot imagine the skill level needed to sit side by side like they do and draw the same picture just slightly off from each other to represent both eyes. I wish I has some red/blue anaglyph glasses so I could see the final image.
December 2012 cannot get here fast enough. :D
