But in the last two decades astronomers have successfully developed indirect detection methods, most of which rely on measuring the effects of orbiting planets on far-off stars. In 1992 ...

Case in point, is the recent remarkable detection of a planet six times the mass of Earth on a highly elliptical 647-day orbit around a nearby star, only slightly less massive than our own sun.

To track these asteroids, scientists have developed new techniques ... the need for better monitoring and planetary defence. How does JWST improve asteroid detection? JWST uses infrared ...

to illustrate its potential for important contributions to planetary science, compared to other indirect and direct methods for the detection and characterization of planetary systems. During the ...
