HiRISE Image Reveals Strange Lack of Coma on Fragmenting Interstellar Visitor 3I/ATLAS

NASA’s Mars Orbiter Captures Unprecedented View of Distant Interstellar Object In a highly anticipated release, NASA officials shared long-delayed images of the mysterious interstellar visitor, 3I/ATLAS (formally designated A/2019 Y4). One particular image, captured by the powerful High-Resolution Imaging Science Experiment (HiRISE) camera aboard the Mars Reconnaissance Orbiter (MRO), revealed an unexpected anomaly that has…

Avi Loeb Details Remarkable Structure of Interstellar Object 3I/ATLAS Jets

Breakthrough Observation Reveals Complex Structure of Interstellar Object 3I/ATLAS Astrophysicist Avi Loeb of Harvard University has released detailed findings concerning the structure of the interstellar object designated 3I/ATLAS, revealing a complex and “remarkable” large-scale morphology involving both a traditional tail and an anti-tail jet system. The observations, captured in early November 2025, provide critical new…

Mysterious Object Discovered Flying Between Earth and Interstellar Comet 3I/Atlas

New Discovery Near the Third Confirmed Interstellar Visitor Astronomers have announced the detection of a previously unknown object traveling through our solar system, positioned in the space between Earth and the Comet 3I/Atlas. The discovery adds a layer of complexity to the study of this unique celestial body, which has garnered significant attention due to…

Interstellar Object 3I/ATLAS Reveals Complex Jet Structure Post-Perihelion

Unprecedented Activity: 3I/ATLAS Exhibits Complex Jet Structure The third confirmed interstellar object, designated 3I/ATLAS, has provided astronomers with a compelling new mystery. Following its closest approach to the Sun (perihelion), the object was observed to be emitting a highly complex jet structure, suggesting non-uniform and vigorous outgassing activity. This crucial observation, detailed by renowned astrophysicist…

Avi Loeb Analyzes Radio Signal from 3I/ATLAS: The Hydroxyl Radical Absorption Debate
