NASA's recent observations of interstellar comet 3I/ATLAS, conducted between August 6 and August 15, 2025, have provided valuable new insights into its properties.

The James Webb Space Telescope used its Near-Infrared Spectrograph on August 6 to gather data on the comet's size, physical characteristics, and chemical composition.

In addition to Webb, NASA's Hubble Space Telescope and the newly launched SPHEREx mission observed the comet, broadening the understanding of its features.

By combining data from Webb, Hubble, and SPHEREx, scientists are developing a comprehensive profile of this interstellar visitor, including its composition and physical features.

The findings from SPHEREx, based on several days of observations, are publicly accessible and contribute significantly to understanding the comet's characteristics.

NASA's team is currently analyzing Webb's data, with a preprint available online that details preliminary findings from these observations.

Despite the interest in the comet, NASA confirms it poses no threat to Earth, emphasizing the importance of coordinated telescope efforts for tracking small solar system bodies.

These ongoing observations support planetary defense initiatives and enhance scientific understanding of solar system evolution.
