But this study shows that you can use the JWST, while it\u2019s doing other work, to opportunistically find small-but-hazardously-sized asteroids. Then, if needed, the JWST can team up with other observatories to track these asteroids and determine if any might head our way. (<a class=\"zZygg UbGlr iFzkS qdXbA WCDhQ DbOXS tqUtK GpWVU iJYzE \" data-testid=\"prism-linkbase\" href=\"https:\/\/www.nationalgeographic.com\/premium\/graphics\/five-asteroids-could-hit-earth\" target=\"_blank\" rel=\"noopener\"><i class=\" \">Read more: These five asteroids post the greatest risk to Earth<\/i><\/a>.)<\/p>\n<h2 class=\"RxNCg ykkUm PvZ nIjPJ PMXYp LmsHF SfAHY mNgye lNbol LBPRq \">Defenders of the Earth<\/h2>\n<p class=\"EkqkG IGXmU nlgHS yuUao lqtkC TjIXL aGjvy \">For the most part, the JWST is busy studying the far-flung cosmos. \u201cAsteroids don\u2019t get a lot of time,\u201d says <a class=\"zZygg UbGlr iFzkS qdXbA WCDhQ DbOXS tqUtK GpWVU iJYzE \" data-testid=\"prism-linkbase\" href=\"https:\/\/www.space.unibe.ch\/about_us\/personen\/dr_raducan_sabina\/index_eng.html\" target=\"_blank\" rel=\"noopener\">Sabina Raducan<\/a>, a planetary scientist at the University of Bern in Switzerland who was not involved with the new study. \u201cBut it\u2019s really nice to see what kind of science you can do just by observing something else.\u201d<\/p>\n<p class=\"EkqkG IGXmU nlgHS yuUao lqtkC TjIXL aGjvy \">Finding asteroids with the JWST is a free benefit, and that it can sometimes spy extremely small space rocks that may elude other telescopes is a welcome discovery. But a more devoted observer is on the horizon. NASA plans to launch another space telescope called the <a class=\"zZygg UbGlr iFzkS qdXbA WCDhQ DbOXS tqUtK GpWVU iJYzE \" data-testid=\"prism-linkbase\" href=\"https:\/\/science.nasa.gov\/mission\/neo-surveyor\/\" target=\"_blank\" rel=\"noopener\">Near-Earth Object Surveyor<\/a> later this decade. It\u2019ll be equipped with infrared detectors and serve as a dedicated asteroid hunter.<!-- -->\u00a0<\/p>\n<p class=\"EkqkG IGXmU nlgHS yuUao lqtkC TjIXL aGjvy \">De Wit is keen to stress that the JWST isn\u2019t going to dethrone the NEO Surveyor before it\u2019s even launched. The JWST will also not sideline any of the ground-based observatories that are already pretty effective at spying asteroids. This includes the almost-complete <a class=\"zZygg UbGlr iFzkS qdXbA WCDhQ DbOXS tqUtK GpWVU iJYzE \" data-testid=\"prism-linkbase\" href=\"https:\/\/www.nationalgeographic.com\/science\/article\/is-there-a-planet-nine-we-may-find-out-vera-rubin-observatory\" target=\"_blank\" rel=\"noopener\">Vera Rubin Observatory<\/a> in Chile, a next-generation, visible-light telescope set to find millions of new asteroids within the first year of operations.<!-- -->\u00a0<\/p>\n<p class=\"EkqkG IGXmU nlgHS yuUao lqtkC TjIXL aGjvy \">\u201cThere is no way JWST is going to infringe on their mission,\u201d de Witt says. But his team\u2019s research suggests it will aid planetary defenders. If the JWST captures the same asteroid over several images, you can start to work out what sort of orbit it\u2019s on\u2014and, with the help of other observatories, work out if it\u2019s a main belt asteroid on its way to becoming a near-Earth
