Their eyes
so scientists can detect smaller objects to study
They use X-Rays from the stars being sucked into them.
Different devices are used to detect different frequency ranges of electromagnetic waves. You simply can't use the same device to detect x-rays, than you would use to detect radio waves, for example.
Forensic scientists use iodine fuming to detect latent fingerprints by sublimating solid iodine crystals, which react with oils and fats on the skin. The iodine forms a visible brown color on the fingerprint ridges, making them easier to visualize and collect as evidence.
they use gel electrophoresis too detect the presence of carp DNA
Scientists use a variety of tools to study the universe, including telescopes (both on Earth and in space), satellites, and instruments that detect different forms of radiation such as radio waves, X-rays, and gamma rays. They also use computer simulations and mathematical models to analyze and interpret the vast amount of data collected from these observations.

Seismometers, strain gauges, tiltmeters, creep meters, high precision GPS, Terrestrial laser scanning equipment and synthetic aperture radar amongst other things are equipment used by scientists to monitor earthquakes and the resultant deformation.Seismometer
they study gasses and look for changes in the volcanoes shape. HOPE I HELPED :D
Scientists use differences and similarities in characteristics such as anatomical structures, DNA sequences, and behaviors to identify and classify different life forms. By comparing these traits across organisms, scientists can determine how closely related different species are and infer their evolutionary history. This information helps scientists understand the diversity of life on Earth and how species are related to one another.
Scientists use telescopes, both ground-based and space-based, to observe objects in space. These telescopes collect and detect various forms of electromagnetic radiation, including visible light, radio waves, and gamma rays, allowing scientists to study celestial objects such as stars, planets, and galaxies.
Scientists use instruments called seismometers to detect and record seismic waves emitted by earthquakes. By analyzing the timing and intensity of these waves at different monitoring stations, scientists can triangulate the epicenter of the earthquake and determine its exact location.
