Interstellar Object 3I/ATLAS May Be A 10-Billion-Year-Old Time Capsule

Interstellar Object 3I/ATLAS May Be A 10-Billion-Year-Old Time Capsule

A team of astronomers has attempted to track the path of interstellar object 3I/ATLAS back into the past, tracing its path through the galaxy in simulations involving over 13 million stars. On July 1, astronomers spotted an unusual object speeding through the Solar System at nearly twice the velocity of previous interstellar visitors ‘Oumuamua and Comet Borisov. The object was …

European Mars orbiter spies interstellar comet 3I/ATLAS zooming past Red Planet (photos)

A European Mars probe witnessed the interstellar comet 3I/ATLAS’ Red Planet flyby last week. On Oct. 3, 3I/ATLAS zoomed within 19 million miles (30 million kilometers) of Mars. The European Space Agency‘s (ESA) ExoMars Trace Gas Orbiter (TGO) was ready for the closeup, snapping imagery of the interloper using its Colour and Stereo Surface Imaging System (CaSSIS). “This was a …

Jupiter-Bound Mission JUICE To Snap Interstellar Comet 3I/ATLAS: “This Campaign Was Unexpected For Everybody”

Jupiter-Bound Mission JUICE To Snap Interstellar Comet 3I/ATLAS: “This Campaign Was Unexpected For Everybody”

We have known about Comet 3I/ATLAS for just over four months, and astronomers across the world have been giddy with excitement. This is only the third known interstellar object to have crossed the Solar System, among the thousands that should be here every day. Researchers have been using many different observatories to study this comet, and soon it will be …

Did NASA’s Perseverance Mars rover just see interstellar comet 3I/ATLAS in the Martian night sky?

Did NASA’s Perseverance Mars rover just see interstellar comet 3I/ATLAS in the Martian night sky?

NASA’s Perseverance Mars rover caught something unusual streaking across the sky above the Red Planet. On Saturday (Oct. 4), Perseverance’s Right Navigation Camera (Navcam) captured an image of a streak of light in the sky above Mars. The date of the image coincides with when interstellar comet 3I/ATLAS was set to make its closest pass to the Red Planet, according …

Interstellar comet 3I/ATLAS will be eyed by Mars and Jupiter probes as it zooms past the sun this month

Interstellar comet 3I/ATLAS will be eyed by Mars and Jupiter probes as it zooms past the sun this month

The European Space Agency is making use of spacecraft designed for Mars and Jupiter missions to track interstellar comet 3I/ATLAS as it continues its journey through our solar system. First spotted in July 2025 by an ATLAS (Asteroid Terrestrial-impact Last Alert System) telescope in Chile, 3I/ATLAS became the third known interstellar object to pass through our solar system. Astronomers identified …

Interstellar comet swinging past Mars as a fleet of spacecraft looks on

Interstellar comet swinging past Mars as a fleet of spacecraft looks on

CAPE CANAVERAL, Fla. — A comet from another star system will swing by Mars on Friday as a fleet of spacecraft trains its sights on the interstellar visitor. The comet known as 3I/Atlas will hurtle within 18 million miles (29 million kilometers) of the red planet, its closest approach during its trek through the inner solar system. Its breakneck speed: …
