SPT0418-47 is a gravitationally lensed, high-redshift, dusty star-forming galaxy, discovered with the South Pole Telescope. [3] Observations with NASA's James Webb Space Telescope (JWST) have revealed the presence of a companion galaxy, [4] [5] which may indicate that SPT0418-47 is a merging system of galaxies.

In June 2023 detection of organic molecules in SPT0418-47 using the Webb telescope was announced. [6]
