Extended Data Fig. 1: Evolution of the position of SPECULOOS-3.
From: Detection of an Earth-sized exoplanet orbiting the nearby ultracool dwarf star SPECULOOS-3
Left: Archival image of the target taken in 1951 using a photographic plate on the Palomar Schmidt Telescope as part of the National Geographic Society - Palomar Observatory Sky Atlas (POSS-I) survey. Right: MuSCAT3 zs band image taken in 2023. The 7 decade-long baseline allowed the target move more than half a degree showing a clear line-of-sight at the past (red circle) and current (blue circle) positions of the target.
