The Race to Study an Interstellar Comet from Deep Space
https://www.scientificamerican.com/article/the-interplanetary-race-to-study-interstellar-comet-3i-atlas/
In early October NASA and European Space Agency (ESA) spacecraft operating at Mars began observing Comet 3I/ATLAS, only the third known interstellar object. Scientists determined that the comet’s coma, a vapor cloud generated when a comet gets close to a star, is full of carbon dioxide, implying it formed somewhere frigid and likely quite far from its star, different from typical comet formation in our solar system. November observations aim to follow the comet, with NASA’s Europa Clipper possibly making contact with its ion tail. Although it's unclear what might be observed, researchers are excited to have a piece of another star system that’s close enough to study in detail.
