Summary

Description
English: This image from the NASA/ESA Hubble Space Telescope shows the distant active galaxy PKG 1830-211. It shows up as an unremarkable looking star-like object, hard to spot among the many much closer real stars in this picture. Recent ALMA observations show both components of this distant gravitational lens and are marked in red on this composite picture.
Deitsch: Auf dieser Aufnahme des NASA/ESA Hubble Space Telescope ist die weit entfernte aktive Galaxie PKS 1830-211 zu sehen. Sie erscheint als unscheinbares, sternartiges Objekt, das schwer unter den vielen deutlich näheren echten Sternen in diesem Bild zu erkennen ist. Neue Beobachtungen mit ALMA zeigen beide Komponenten dieses entfernten Gravitaionslinsenobjekts und sind auf diesem zusammengesetzten Bild mit roten Kreisen markiert.
