Vizualizing Kepler Exoplanets

from Discovery.com:

Last week the Kepler satellite released results indicating that the mission had discovered over 1200 planetary candidates (most of which are expected to be actual planets) orbiting stars in our neighborhood of the galaxy. In technical terms, that’s a “buttload.” A back-of-the-envelope calculation implies that there might be a million or so “Earth-like” planets in our Milky Way galaxy. A tiny fraction of the hundred billion stars we have, but still a healthy number.

But you know what’s really cool? The data visualization.

A couple of science results pop out — you could have figured them out without the visualization, but it makes it much easier. First, most of these planets are closer to their stars than Earth is to the Sun. Second, most of the planets are equal to or a bit larger than the Earth. Both features make sense in terms of Kepler’s search technique — the mission looks for tiny dips in the brightness of stars as planets pass in front, which favors larger planets with shorter orbits. It’s unclear whether the overall planet distribution also shares these features.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. It’s like EVE online, but for real (assuming one subscribes to the theory that EVE online isn’t real). Great post!

  2. totally awesome

    i wonder why there are so many planets closer in
    is it because of the star’s gravity and how they formed
    or is it just the detection method allows us to find more planets that are closer in to the star
