By the way, the #interstellar #comet 3I/2025 N1 (ATLAS) is on my free Bright Comets #iOS app, in case you want to know where it is right now. Spoiler: it's still very faint at 16 mag. But it should brighten up to 12 mag by October.

3I/Atlas, possibly much older than the Solar System.
Kudos to Hopkins and Lintott for making a _prediction_ (about the composition of the object).
That is something that separates proper science from stamp collection, to borrow a famous quip.
Note how interstellar objects have the privilege of a single letter ("I") in their designations.

For those of you who have been distracted by other (bad) news, our good friends at ATLAS (hey, LarryD!!!) just spotted what looks like the 3rd ever interstellar object ever discovered.
Known as 3I/ATLAS (and now, C/2015 N1) it's coming it hot in a very eccentric orbit before it'll blast past Mars and out of our solar system again.
Cool animation here:

And there are already three papers: https://arxiv.org/abs/2507.02757 (Discovery and Preliminary Characterization of a Third Interstellar Object: 3I/ATLAS), https://arxiv.org/abs/2507.05252 (Interstellar comet 3I/ATLAS: discovery and physical description) and https://arxiv.org/abs/2507.05226 (Initial VLT/MUSE spectroscopy of the interstellar object 3I/ATLAS).
Interstellar Comet 3I/ATLAS
This rare visitor is only the third known object from beyond our Solar System. Currently approaching from Jupiter’s distance, it will pass inside Mars’ orbit in late October. Though it will not come near Earth, it offers a rare chance to study material from another star system.

A comet the size of a small city... just passing by our neighborhood onto the next solar system in a few million years.

Astronomen entdecken interstellaren „Besucher“
Extrasolares Objekt 3I/ATLAS rast in hohem Tempo auf das innere Sonnensystem zu
Wow,, hohes Tempo !
Der Brocken hat einen ungefähren Durchmesser von 12Km und ist mit ca. 250 000 km/h unterwegs.

The NASA-funded #ATLAS (Asteroid Terrestrial-impact Last Alert System) survey telescope in Rio Hurtado, Chile, first reported observations to the Minor Planet Center of #comet 3I/ATLAS on July 1, 2025.
Comet 3I/ATLAS is the 3rd known object from outside our solar system to be discovered. Astronomers have categorized this object as #interstellar because of the hyperbolic shape of its orbital path.
Comet 3I/ATLAS poses no threat to Earth and will remain far away.
