NASA’s James Webb Space Telescope observed interstellar comet 3I/ATLAS Aug. 6, with its Near-Infrared Spectrograph instrument. The research team has been analyzing insights from Webb’s data, and a preprint is available online. Webb is one of NASA’s space telescopes observing this comet, together providing more information about its size, physical properties, and chemical makeup. For example, NASA’s Hubble Space Telescope and the recently launched SPHEREx mission have also observed the comet. While the comet poses no threat to Earth, NASA’s space telescopes help support the agency’s ongoing mission to find, track, and better understand solar system objects.
NASA’s SPHEREx (Spectrophotometer for the History of the Universe, Epoch of Reionization, and Ice Explorer) also observed the interstellar comet 3I/ATLAS from August 7 to 15. The SPHEREx team has been analyzing insights from this data, and a research note is available online. The agency’s SPHEREx is one of NASA’s space telescopes observing this comet, together providing more information about its size, physical properties, and chemical makeup. For example, NASA’s Webb and Hubble space telescopes also recently observed the comet.
