The Hubble House Telescope has taken its preliminary pictures of comet 3I/ATLAS, a comet visiting us from past our photo voltaic system that not too long ago fell aside — however not earlier than it struck a pose for the cameras. It is solely the third such object ever recognized, after 1I/ʻOumuamua in 2017 and 2I/Borisov in 2019. The topic of quite a few scientific tweets and a few frantic searches by astronomers anxious to determine simply what it’s — and the place it got here from — earlier than it’s gone into the pitch black of deep house ceaselessly, 3I/ATLAS was first sighted by the ATLAS survey telescope on July 1, 2025.

Historical Interstellar Comet 3I/ATLAS Gives Clues to Planetary Methods Past Our Personal

According to As per House.com, current studies point out that 3I/ATLAS could possibly be some 7 billion years previous, nicely past the 4.6 billion years of our photo voltaic system. That is a sign that the comet arose within the extra historic components of the Milky Way, which might give researchers a uncommon glimpse of what the early days of different planetary methods had been like. Undergraduate researcher Astrafoxen first flagged the Hubble photographs on Bluesky, noting the comet’s “good and puffy” coma, regardless of interference from cosmic rays.

A newly accessible preprint paper has already revealed that 3I/ATLAS incorporates considerable water ice and a mud make-up resembling D-type asteroids—organic-rich our bodies sometimes discovered within the outer photo voltaic system. In contrast to ultrared trans-Neptunian objects, D-types are believed to have excessive carbon and silicate content material, doubtlessly shedding mild on the comet’s deep-space origins and risky chemistry.

The comet 3I/ATLAS was found simply because the Vera C. Rubin Observatory was gearing as much as perform its preliminary observations of the heavens, dovetailing with the LSST’s anticipated discovery of many extra interstellar objects within the coming decade.

Till then, 3I/ATLAS holds the astronomical highlight. Its temporary solar system passage presents a treasured alternative for researchers to analyse the fabric make-up of alien planetary methods. The Hubble photographs, now accessible for obtain, are anticipated to assist future papers as scientists proceed to unravel the story of this historic cosmic traveller.
