The Cosmic Catalog

PythonpandasNumPyPlotly

NASA’s Kepler mission stared at one patch of sky and flagged 9,564 objects of interest, possible planets around other stars. The Cosmic Catalog is a tour through that dataset.

It starts with every candidate plotted where Kepler saw it, sorts the host stars by temperature and brightness, places the planets by size and orbit against the habitable zone, and ends with the orbital architecture of the 196 candidates that fall inside it. Each figure below is interactive. Hover, zoom, and pan.

01Sky MapFull screen

All 9,564 Kepler Objects of Interest plotted where Kepler actually saw them, the full field of view in a single frame.

02HR DiagramFull screen

The host stars sorted the classic way, by surface temperature and brightness, so you can see what kinds of stars these planets orbit.

03Radius vs PeriodFull screen

Every planet placed by size and orbital period, with the habitable zone marked, so the potentially temperate worlds stand out.

04Habitable AtlasFull screen

The orbital architecture of all 196 candidates that fall in the habitable zone, each system drawn out so you can scan them side by side.

Dataset

Built from NASA’s Kepler Objects of Interest catalog, 9,564 candidates in the Kepler field of view.
