US EditionNew interstellar comet will keep a safe distance from Earth, NASA says
UNITED STATES, JUL 12 – 3I/ATLAS is likely over 7 billion years old, making it the oldest known comet and a pristine remnant from the Milky Way’s thick disk, researchers say.
- NASA confirmed that interstellar comet 3I/ATLAS will pass safely behind the Sun in late October 2025.
- NASA confirms 3I/ATLAS will safely pass Earth in late October 2025, with its hyperbolic orbit indicating interstellar origin, first spotted July 1 by the ATLAS survey in Chile.
- ESO's Very Large Telescope captured images and a timelapse, confirming the comet's high velocity of nearly 60 km/s , indicating its interstellar origin.
- Amateur astronomers can observe 3I/ATLAS in late 2025, while NASA's JWST and Hubble plan detailed studies of its composition and spin.
- NASA confirms 3I/ATLAS will safely pass Earth in late October 2025 at a distance behind the Sun, aiding long-term studies of interstellar object populations and planetary formation.

Spotting New Interstellar Comet C/2025 N1 ATLAS
It’s the question of the hour. On the first day of the month July 1st, the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile spotted an interstellar interloper, which would receive the official designation C/2025 N1 ATLAS or 3I/ATLAS. The ‘I’ is a rare ‘interstellar’ designation, only the third such object known of after 1I/ʻOumuamua and 2/I Borisov. But can we see it? Such a spectacle as actually seeing an int…
The ATLAS telescope in Chile was responsible for identifying this celestial body, a finding that mobilized scientific teams from several continents to reveal unprecedented data on the early evolution of the galaxy and the formation of planetary systems
3I/ATLAS: Scientific paper details what's known about the third-ever interstellar object
When the news started to spread on July 1, 2025, about a new object that was spotted from outside our solar system, only the third of its kind ever known, astronomers at Michigan State University—along with a team of international researchers—turned their telescopes to capture data on the new celestial sighting.
Mystery discovery in space is most likely the 'oldest comet ever seen', say researchers
The object seems to be travelling on a steep path - suggesting it came from the Milky Way's "thick disk", an area of ancient stars that orbits above and below the thin plane where most stars reside.
He traveled billions of years through the darkness of space. Now researchers are emanating his story from interstellar comet 3I/ATLAS.
