Will we ever have confirmation of life outside our solar system?

Analysis

This is the first confirmed live observation of the colossal squid, Mesonychoteuthis hamiltoni, in its natural habitat. The team on Schmidt Ocean Institute's Research Vessel Falkor (too) captured footage of the 30-centimeter-long squid (nearly one foot) at a depth of 600 meters (1968 feet) using their remotely operated vehicle SuBastian on March 9 during an Ocean Census flagship expedition searching for new marine life. The expedition took place in the remote South Sandwich Islands in the South Atlantic Ocean. This year (2025) is the 100-year anniversary of the identification of the colossal squid, which are estimated to grow up to seven meters (23 feet) in length.
