A thriller interstellar object found by British astronomers is more than likely the oldest comet ever seen.
The “water ice-rich” customer, which has been given the identify 3I/ATLAS, is the primary object to succeed in us from a very completely different area of our galaxy, researchers have stated.
Simply two different objects have entered our photo voltaic system from elsewhere.
In contrast to its predecessors, 3I/ATLAS appears to be travelling on a steep path that implies it got here from the Milky Means’s “thick disk”, an space of historic stars that orbits above and under the skinny airplane the place most stars reside.
College of Oxford astronomer Matthew Hopkins defined: “All non-interstellar comets equivalent to Halley’s Comet shaped with our photo voltaic system, so are as much as 4.5 billion years outdated.
“However interstellar guests have the potential to be far older, and of these identified about to this point our statistical technique means that 3I/ATLAS may be very prone to be the oldest comet we now have ever seen.”
3I/ATLAS could possibly be about three billion years older than our photo voltaic system.
It was first noticed on 1 July 2025 by the ATLAS survey telescope in Chile, when it was roughly 670 million kilometres from the solar. Earth is 149 million km away from the solar.

Professor Chris Lintott, the co-author of the research, stated: “That is an object from part of the galaxy we have by no means seen up shut earlier than.
“We expect there is a two-thirds probability this comet is older than the photo voltaic system, and that it has been drifting via interstellar area ever since.”

As 3I/ATLAS will get nearer to the solar, daylight will warmth its floor and set off the outgassing of vapour mud that creates a comet’s glowing tail.
Members of the general public might have the ability to catch a glimpse of 3I/ATLAS within the coming months, as researchers say it needs to be seen via reasonably-sized newbie telescopes in late 2025 and early 2026.
