What do scientists use to obtain data in a hostile environment?

In hostile environments, scientists often use specialized instruments and technology, such as remote sensing devices, autonomous underwater vehicles (AUVs), and drones. These tools enable data collection without direct human presence, minimizing risks. Additionally, they may deploy sensors and monitoring stations that can withstand extreme conditions to gather real-time data. This approach allows for the study of phenomena in places like deep oceans, polar regions, or active volcanoes.
