——改编自Asteroid collision shows how much amateur astronomers have to offer
Last September, NASA’s Double Asteroid Redirection Test (DART) spacecraft intentionally collided with an asteroid, and many telescopes were trained on the event. Among the telescopes were tho operated by amateur astronomers who are skilled skywatchers but do not work full-time in astronomy. Some of the teams on France’s Réunion island and one in Nairobi were able to watch the impact in real time. The obrvations made by the amateur astronomers contributed to a study published in Nature, which described how the asteroid named Dimorphos became temporarily brighter and redder as the spacecraft hit it.
This event is yet another example of the contribution that amateur astronomers have made to understanding celestial phenomena. In the past, they have helped astronomers better understand variable stars, classify galaxies, and even arch for extraterrestrial signals. Amateur astronomers have discovered comets and other celestial occurrences, identified pr
eviously unknown objects, and obrved old photographs of the night sky to uncover new phenomena.

The coordination between amateur and professional rearchers is not unique to astronomy. In January, rearchers relead BirdFlow, a model that predicts where North American bird species will migrate to using records from an online databa called eBird, which receives millions of contributions each year from amateur ornithologists.出乎意料之外
Community science benefits from gathering data from multiple contributors, allowing for further calibration and confirmation of obrvations. In the ca of the DART impact, the rapid gathering, distribution, and publication of information by the amateur scientists was valuable, and other teams continue to monitor the DART asteroid system to refine our understanding of its orbit around the sun.
deenaAs science becomes more specialized and dependent on specific instruments, it is tempting to dismiss the role of amateur scientists. However, more working rearchers should consider how they can creatively harness the enthusiasm of their amateur colleag
ues to assist with obrvations and data analysis. The next time someone is looking for an obrvation partner or help with analyzing data, they should consider turning to an amateur scientist.
