Scientist Claims Mysterious Interstellar Comet Could Be Alien Technology.Here's What We Know
A newly discovered interstellar comet, 3I/ATLAS, has sparked debate in the scientific community after Harvard astrophysicist Avi Loeb and his team proposed a speculative idea-that it might be an alien spacecraft.

Harvard Scientist Claims Rare Interstellar Object Might Be "Alien Technology"
The comet will reach its closest point to the Sun (perihelion) on October 29, 2025, passing just inside Mars' orbit

Hubble Captures First Images of Ancient Interstellar Visitor Comet 3I/ATLAS
Hubble has captured images of comet 3I/ATLAS, an ancient interstellar object likely 7 billion years old. As only the third known visitor from beyond the solar system, it offers rare insights into distant planetary systems. With its water ice and D-type asteroid-like dust, 3I/ATLAS is now under global scientific scrutiny before it vanishes back into...

Gemini North Telescope Spots Interstellar Comet 3I/ATLAS Racing Through Solar System
Gemini North has imaged 3I/ATLAS, the third interstellar object to enter our solar system. Larger than its predecessors and possibly older than our solar system, the comet will pass closest to the Sun on Oct. 30 before returning to deep space. Scientists worldwide are racing to gather data during its brief visit.

This New Interstellar Object Could Possibly Be The Oldest Comet Ever Seen
A mysterious object, first observed hurtling across the solar system on July 1, has now been identified as "very likely to be the oldest comet ever."

ESO Captures Clear Images of Interstellar Comet 3I/ATLAS Using VLT
The European Southern Observatory’s Very Large Telescope has captured the clearest images so far of comet 3I/ATLAS, an interstellar visitor first spotted on July 1, 2025. Identified by its hyperbolic orbit, the comet is only the third interstellar object recorded passing through our solar system. The VLT’s deep image and timelapse confirm it is...

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...

Astronomers Discover 3I/ATLAS, Largest Interstellar Comet Yet Detected
Astronomers have discovered 3I/ATLAS, the third known interstellar comet to pass through our solar system. Detected by the ATLAS telescope in Chile, it’s racing inward at 150,000 mph and will swing closest to the Sun in October. Estimated to be 10–20 kilometers across, it is likely the largest interstellar object observed so far. Signs of comet...

New Interstellar Comet 3I/ATLAS Speeds Through Solar System
Astronomers have identified 3I/ATLAS as the third confirmed interstellar comet, racing through the solar system at 68 km/s. Discovered on July 1, it will pass near the sun in October. Skywatchers can view this rare object live online tonight, thanks to a live stream by the Virtual Telescope Project using observatories in Italy.

NASA Detects 'Interstellar Visitor' Hurtling Through Solar System
The comet-like body, designated 3I/ATLAS, is hurtling towards the Sun at a speed of over 60 kilometres per second

Organic Molecules in Space: A Key to Understanding Life's Cosmic Origins
Organic molecules, the building blocks of life, have been discovered across space—from interstellar clouds to asteroids and comets. Findings from missions like Rosetta, Hayabusa2, and Osiris-Rex reveal that these compounds existed long before the Sun formed. Scientists believe organic molecules survived planetary formation in protoplanetary disks...

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.

NASA Video Shows Comet Borisov Visiting From Outside Our Solar System
NASA's Hubble Telescope has photographed the interstellar Comet Borisov at a distance of 260 million miles (about 41.84 crore km) from Earth. Comet Borisov is the only second interstellar object to ever enter our solar system: the first such visitor was an object officially named "Oumuamua".

Comet 'Most Pristine' Object From Outer Space Seen In Solar System
A newly observed interstellar comet is the most pristine visitor from outer space ever seen in our Solar System, according to a pair of studies released Tuesday detailing its unique characteristics.

Interstellar Gatecrasher 2I/Borisov Is No Ordinary Comet
"This shows that 2I/Borisov is not a completely alien object, and confirms some similarity with our 'normal' comets, so the processes that shaped it are comparable to the way our own comets formed," said Martin Cordiner, an astrobiologist working at NASA's Goddard Space Flight Center.
