Webb observations of interstellar comet 3I/ATLAS

Webb observations of interstellar comet 3I/ATLAS

The NASA/ESA/CSA James Webb Space Telescope observed interstellar comet 3I/ATLAS on 6 August 2025 using its Near-Infrared Spectrograph. The research team is analysing Webb’s data, with a preprint now available online. Webb is one of several space telescopes studying this comet, helping to reveal its size, physical properties, and chemical composition. For example, the NASA/ESA Hubble Space Telescope and NASA’s …

James Webb Space Telescope’s first observation of interstellar comet 3I/ATLAS reveals something strange

Researchers used NASA’s James Webb Space Telescope to observe 3I/ATLAS on Aug. 6. (Image credit: NASA/James Webb Space Telescope) Astronomers have found something strange in the James Webb Space Telescope‘s first images of interstellar comet 3I/ATLAS as it hurtles toward our sun, according to a new study. The telescope’s initial observations suggested that 3I/ATLAS has one of the highest carbon …

NASA James Webb Space Telescope observes interstellar comet 3i/ATLAS

Aug. 27 (UPI) — NASA observed interstellar comet 3I/ATLAS through the lens of the James Webb Space Telescope for the first time. On Aug. 6, the telescope with its near-infrared Spectrograph instrument analyzed the comet as it provided more information about its size, physical properties, and chemical makeup. This kind of observation can help make clear what conditions were like …

This Visiting Interstellar Comet Just Keeps Getting Weirder

This Visiting Interstellar Comet Just Keeps Getting Weirder

Ever since interstellar comet 3I/ATLAS whizzed into our cosmic neighborhood in July, astronomers have been racing to uncover its characteristics. Now that the powerful James Webb Space Telescope has taken a good look at this icy interloper, it seems to be weirder than anyone imagined. A preprint submitted to the Astrophysical Journal Letters for peer review on Monday, August 25, …

James Webb Space Telescope takes 1st look at interstellar comet 3I/ATLAS with unexpected results

The James Webb Space Telescope (JWST) has observed the interstellar visitor 3I/ATLAS for the first time. The powerful space telescope trained its infrared vision and its Near-Infrared Spectrograph instrument (NIRspec) on the comet on Aug. 6, 2025. Discovered on July 1 by the ATLAS (Asteroid Terrestrial-impact Last Alert System) survey telescope, 3I/ATLAS is just the third-ever object found drifting through …

New Study Fuels Debate Over World-Changing Comet Strike 12,800 Years Ago

New Study Fuels Debate Over World-Changing Comet Strike 12,800 Years Ago

Roughly 12,800 years ago, as Earth was emerging from its last great ice age, temperatures in the Northern Hemisphere suddenly plummeted back to near-glacial conditions. The cause of this abrupt shift—known as the Younger Dryas cool period—remains a mystery to this day, but new evidence may give credence to its most controversial explanation. Researchers analyzed sediment cores extracted from the …
