New research suggests planets similar to Earth are much more common across the galaxy than previously thought.
And the boffins behind this revelation have also come up with a simple chemical recipe for creating habitable worlds suitable for use by advanced super-powered intelligences and/or deities etc.
"Our solar system is not as unique as we might have thought," says Courtney Dressing, graduate student at the Harvard-Smithsonian Center for Astrophysics.
Ms Dressing bases this assertion on data from the HARPS-North (High-Accuracy Radial velocity Planet Searcher, Northern) instrument on the 3.6-metre Telescopio Nazionale Galileo in the Canary Islands. This is designed to accurately measure the masses of small, Earthish-sized worlds. Once you have mass and volume, as any fule kno, you have density and thus a fair notion of what a given alien world is made of - and this tells you whether it can be much like Earth.
So chuffed are the Harvard boffins with this discovery that they've come up with a handy "recipe" for cooking up a world with Earth-esque life on it, thus:
1 cup magnesium
1 cup silicon
2 cups iron
2 cups oxygen
½ teaspoon aluminum
½ teaspoon nickel
½ teaspoon calcium
¼ teaspoon sulfur
dash of water delivered by asteroids
Blend well in a large bowl, shape into a round ball with your hands and place it neatly in a habitable zone area around a young star. Do not over mix. Heat until mixture becomes a white hot glowing ball. Bake for a few million years. Cool until color changes from white to yellow to red and a golden-brown crust forms. It should not give off light anymore. Season with a dash of water and organic compounds. It will shrink a bit as steam escapes and clouds and oceans form. Stand back and wait a few more million years to see what happens.
If you are lucky, a thin frosting of life may appear on the surface of your new world.
