Amateur astronomers make significant asteroid collision discovery.

Amateur astronomers played a key role in observing the impact of NASA's Double Asteroid Redirection Test (DART) spacecraft on the asteroid Dimorphos. The four telescopes used were of a type popular in the amateur-astronomy community, and the observational data was uploaded to a server for professional astronomers to analyze. This is just one example of how amateur astronomers have contributed to scientific research, including discovering comets and identifying previously undescribed phenomena. The collaboration between amateur and professional researchers highlights the importance of community science in collecting and verifying data.
