As NASA continues to study the interstellar comet 3I/ATLAS, two space telescopes have made new observations, together providing more information about its size, physical properties, and chemical makeup. NASA's James Webb Space Telescope observed the object with its Near-Infrared Spectrograph instrument go.nasa.gov/4n3RDS7 and the new SPHEREx telescope contributed new data as well go.nasa.gov/47IVWO3 All about this comet, the third such interstellar visitor that NASA has observed: science.nasa.go

3I/ATLAS is no ordinary comet... it came from beyond our solar system. NASA’s SPHEREx mission recently observed this interstellar visitor, teaming up with NASA's James Webb Space Telescope and NASA's Hubble Space Telescope, to reveal more about its size, physical properties and chemical makeup: go.nasa.gov/47IVWO3 | NASA 360
