Exoplanet Statistics

There are very special statistics where the survey instrument is a telescope and the data are far from our world.


There’s a fascinating animated visualisation of this survey –  and an award winning one: WORLDS. The Kepler Planet Candidates.


CinéGlobe yesterday (19th October 2013) awarded the Data Visualization Prize at the Imagine Science Film Festival to the film “Worlds, The Kepler Planet Candidates”, a simple yet stunning depiction of the Kepler search for earth-like planets orbiting other stars. Director Alex Parker creates a subtle visual narrative that leads the viewer to the gradual realization that our earth may be very far from the only living planet in our universe.’

Exoplanets, Kepler’s Candidates?

At first I didn’t understand what’s behind this visualisation:

‘This animation shows the 2299 high-quality (multiple transits), non-circumbinary transiting planet candidates found by NASA’s Kepler mission so far. These candidates were detected around 1770 unique stars, but are animated in orbit around a single star. They are drawn to scale with accurate radii (in r / r* ), orbital periods, and orbital distances (in d / r*). They range in size from 1/3 to 84 times the radius of Earth. Colors represent an estimate of equilibrium temperature, ranging from 4,586 C at the hottest to -110 C at the coldest – red indicates warmest, and blue / indigo indicates coldest candidates.’ (From CinéGlobe)

But this video made it clear:


All Candidates (till now)

And these are all the detected stars (huge ones!) with planets in their orbits. Much more on NASA’s Kepler Homepage

This is a graphic of 2,740 candidate planets in transit. The planets are small black disks against the bright disk of each star.


Who knows?

Perhaps out there on one of these planets live statisticians. And they are about to visualise how many planets have statisticians visualising data … .
