Running Across the Moon

Similarly, if you moved fast enough, you could be long gone by the time the surface was broken. That's how water striders and basilisks do it, but other animals actually have other methods of walking on water depending on how strict you are about the word "walk". If you've ever seen a sea-animal show at an aquarium, you know that dolphins prove you don't even need legs to "walk" on water.

Humans train dolphins to do this all the time, but it's a behavior that's never been seen in the wild, except in dolphins who have interacted with other dolphins who learned the trick from humans. But lately, biologists have spotted wild dolphins doing it entirely on their own.
Our correspondent turned out to be none other than Professor Emeritus of Observational Astronomy and a researcher into stellar radial velocities and binary-star orbit determination at the Institute of Astronomy, Cambridge University. Since the gravity on the moon is about 17 percent of Earth's gravity, that means that running across a lake is certainly possible — it's just closer to the "elite athletes only" side of the spectrum. No ordinary observer of the skies, prof Griffin makes a majority of his observations on-site with his 36 inch telescope. Turnaround times are determined by the content of your order and may be extended in busier periods. Depending on the medium chosen and the size of your print, we may use different methods but it will always arrive ready to hang.
Of course, this "walking" doesn't involve staying completely above the water line — instead, the dolphins propel themselves with their tail fins underwater, and it's that forward momentum that keeps them from falling through. Another water-walking animal does so more naturally.

The tiny bird known as the storm petrel is notable for appearing to walk calmly across the surface of the ocean. However, it's more of a half-hearted flight than a stroll — these birds are just carrying themselves right above the water so that they can hunt more effectively. Can't get enough silly science?

It is a spontaneous affair, with an email simply going out a few hours before the event to confirm proceedings. No ordinary observer of the skies, prof Griffin makes a majority of his observations on-site with his 36 inch telescope.

More binary-star orbits have been determined by him than by any other observatory in the world. So when he contacted us to suggest we stage our run two days before the full moon, we were all ears. We had hoped to stage our off-road half marathon night race, The Moonlit Flit, under the light of a full moon.

A full moon near the winter solstice, on 21 December, occupies the same place in the sky as the sun does at the summer solstice on 21 June. It is high in the sky, and is highest at midnight. In open landscapes, this is enough light to run by. At the same time you need to have it reasonably high in the sky, which means waiting until late in the evening.
As prof Griffin explains: So the night previous to a full moon, the moon will rise about an hour before sunset, two nights previously it will rise two hours before — and so would then be at a reasonable altitude by the time the sky was dark. On the actual night of full moon, it will be on the meridian very near midnight, but on the previous night it will reach the meridian around 11pm, and on the one before that 10pm.
So it could be satisfactorily bright by about 9pm on the night before it is full and at 8pm on the night before that.
