They use advanced technology for detection from "summary" of Exoplanets and Alien Solar Systems by Tahir Yaqoob
Scientists have made tremendous progress in the field of exoplanet detection due to the use of advanced technology. This technology allows researchers to observe distant stars and analyze the subtle changes in their brightness that may indicate the presence of orbiting planets. One such technique is the transit method, where astronomers look for periodic dips in a star's brightness as a planet passes in front of it. Another method involves measuring the slight wobble in a star's position caused by the gravitational pull of an orbiting planet. In addition to these direct detection methods, scientists also use indirect techniques to infer the presence of exoplanets. For example, the astrometry method involves measuring the tiny changes in a star's position in the sky as it is influenced by an orbiting planet. Furthermore, the radial velocity method looks for the slight shifts in a star's spectrum caused by the gravitational tug of an orbiting planet. The use of advanced telescopes and instruments has greatly enhanced our ability to detect exoplanets, with many new discoveries being made in recent years. For instance, the Kepler Space Telescope has identified thousands of exoplanet candidates by observing the dimming of stars as planets pass in front of them. Similarly, the James Webb Space Telescope is expected to revolutionize exoplanet research by providing unprecedented levels of sensitivity and resolution.- The use of advanced technology for exoplanet detection has opened up new possibilities for exploring the vast diversity of alien solar systems beyond our own. By continuously improving our tools and techniques, scientists are poised to make even more groundbreaking discoveries in the field of exoplanet research in the years to come.
