Explainer video for Earth-Like. (Vimeo edition with subtitles here)
Are we alone? The question hangs over each discovery of an Earth-sized planet as we speculate on its habitability. But how different and varied could these worlds really be? Perhaps the best way to get a flavor of this potential diversity is to build a few planets.
This is the idea behind Earth-Like: a website and twitter bot that lets you build your own Earth-like world. Earth-Like begins with a planet that resembles our Earth today, with oceans flowing over the surface and an atmosphere that maintains the global average temperature at a comfortable 15°C (59°F) on our orbit within the habitable zone. By making changes to the fraction of exposed land, the volcanic rate and position within the habitable zone, you can change the conditions on our planet into wildly different environments from desert to snowball.
Earth-Like can create a visualisation of what your planet might look like. This one is 91% covered with land, sitting in the middle of the habitable zone with 5 x the volcanic rate of Earth today! Its average temperature is about 9°C (48°F).
The concept for Earth-Like began during a workshop on ...
