Mystery Deepens as Interstellar Comet 3I/ATLAS Brightens Unexpectedly Near the Sun
Interstellar comet 3I/ATLAS defied expectations during its 2025 solar flyby, brightening far faster than predicted. Observatories worldwide recorded a blue coma rich in exotic gases, suggesting unique chemistry from another star system. Scientists are investigating whether its unusual composition or speed caused the outburst, marking a new interste...

New Interstellar Object 3I/ATLAS Could Reveal Secrets of Distant Worlds
Astronomers have confirmed the arrival of 3I/ATLAS, only the third interstellar object ever spotted in our solar system. First seen on July 1, 2025, by the ATLAS survey team in Chile, it was quickly identified by its unusual hyperbolic orbit and comet-like tail. Larger and brighter than either 1I/ʻOumuamua or 2I/Borisov, 3I/ATLAS is estimated to b...

Harvard Professor, Searching For Remains Of Interstellar Object, Finds "Promising Material"
Two confirmed interstellar objects have entered the solar system in recent years: 'Oumuamua' in 2017, and Comet Borisov in 2019.

Unidentified Interstellar Bids Goodbye To Solar System, Leaves Mystery Behind
Oumuamua's speed and trajectory revealed it originated outside the solar system, making it the first known interstellar object.

First Known Interstellar Object 'Oumuamua' Could Be Alien Listening Device, Harvard Professor Speculates
A Harvard astrophysics professor has suggested the mysterious interstellar object “Oumuamua” could be linked to the dozens of UAVs reported by US military planes over the years. Avi Loeb claimed that Oumuamua, first discovered in 2017, could be a listening device designed by an extraterrestrial intelligent civilisation that is dropping “senso...

Scientists Say Cigar-Shaped Interstellar Object Not An Alien Spaceship
After investigating the nature of a mysterious and apparently cigar-shaped object called 'Oumuamua spotted in 2017 speeding through our solar system, astronomers remain uncertain over how to classify it, but are confident it is not an alien spaceship.

Scientists Push Back Against Harvard 'Alien Spacecraft' Theory
Oumuamua, the first interstellar object known to enter our solar system, accelerated faster away from the Sun than expected.

Cigar-Shaped Interstellar Visitor 'Oumuamua Classified As Comet
The reddish cigar-shaped object called 'Oumuamua spotted last year tumbling through space is a comet, scientists said on Wednesday, solving the mystery over how to classify the first interstellar object found passing through our solar system.

An Alien Star Sideswiped Our Solar System And Sent Comets Reeling, Scientists Say
Some 70,000 years ago, when humans and Neanderthals shared the planet, an alien star streaked through the outer edges of our solar system and jostled its contents, astronomers say.

Visitor From Alien Star System Wears Insulating Coat: Astronomers
A cigar-shaped rock zooming through our Solar System -- the first object from a foreign star system ever spotted in our midst -- is cloaked in a coat of organic material, astronomers said Monday.

This Visitor From Beyond Our Solar System Will Be Probed For Signs Of Life
Our solar system has a visitor. It's cylindrical, dark and reddish, a quarter-mile long. The object won't be staying. This fall, astronomers announced that the thing came blazing into our neck of the galaxy at speeds of up to 196,000 mph. It is now headed away as quickly as it came.

Why Asteroid That Zipped Through Our Solar System Last Month Is Important
A rocky cigar-shaped object detected in space last month came from another solar system, astronomers said Monday as they confirmed an unprecedented observation.
