Satellite Eyes Reveal Subsea Volcano Eruption, but Seafloor Remains a Puzzle

NASA satellites imaged an underwater volcanic eruption in the Bismarck Sea near Papua New Guinea, but scientists lack high‑resolution seafloor maps to pin down the vent or how the eruption reshaped the seafloor; thermal anomalies and a growing plume indicate a shallow source, and a new island might form, though the timeline and exact effects remain uncertain, highlighting how satellite data guide deep‑ocean and future off‑Earth exploration.
