Finding Earth 2.0
Galactic context

Our place in the galaxy

The Sun's position here is real, computed from a standard equatorial-to-Galactocentric transform, not assumed. The Milky Way's own spiral shape behind it is a labelled illustration -- we are inside the galaxy and cannot photograph its structure from outside. Every system plotted, and every detection-distance shell, comes from this catalogue's actual measured coordinates.

The spiral arms, central bar, and Orion Spur are drawn schematically — nobody has photographed the Milky Way from outside it — but the arm names and the barred structure are real, established from infrared star-count surveys (Benjamin et al. 2005, ApJ 630, L149), not invented for this illustration. The Sun's position is real: 8.18 kpc from the Galactic Centre (GRAVITY Collaboration (2019), A&A 625, L10), 20.8 pc above the midplane (Bennett & Bovy (2019), MNRAS 482, 1417). The dashed cyan ring marks the extent of the panel on the right — everything we've found so far is that small a fraction of the galaxy. The faint cyan dots are every one of the 6,327 systems in this catalogue, plotted at their real position — at this scale they sit almost on top of the Sun, which is itself the finding; use the + control above to zoom into the cluster and see it resolve. Zoomed in, one thin streak reaches toward the Galactic Centre — that is not planets being more common there. Percentage of each method's detections whose real sky position (not the Galactocentric transform) falls within 10 degrees of Sagittarius A*. High for microlensing because bulge-monitoring surveys point there by design, not because planets are physically more common in that direction. In this catalogue, 98.6% of Microlensing detections fall within 10° of Sagittarius A* on the real sky, against 0.1% for Transit and 1.3% for Radial Velocity — computed straight from each system's archive right ascension and declination, independent of the Galactocentric coordinates plotted above.

The furthest distance this catalogue actually contains a confirmed detection at, per method -- not a theoretical instrument sensitivity limit, which depends heavily on the target star's brightness and the planet's size. Radius is log-scaled (true 3-D distance from the Sun, same compression the 3-D map uses) so every shell stays legible at once; angle is each system's real projected direction.
