Kapteyn b and c: Two Exoplanets Found Orbiting Kapteyn’s Star

This artistic representation shows the potentially habitable exoplanet Kapteyn b and the globular cluster Omega Centauri in the background. It is believed that this cluster is the remaining core of a dwarf galaxy that merged with our own Milky Way Galaxy billions of years ago bringing Kapteyn's star along.
