Keywords: Interstellar comet
Interstellar comet 3I/ATLAS is now racing away from the inner solar system after a fleeting but revealing visit that has given astronomers fresh insight into the chemistry of deep space. The icy body is only the third confirmed object known to have entered our planetary neighborhood from another star......
A Harvard astrophysicist has called for a worldwide early-warning system to spot high-speed visitors from beyond our solar system, spurred by unusual traits in the interstellar comet 3I/ATLAS. Discovered in July 2025 as it streaked through our cosmic neighborhood, the comet's peculiarities have prompted......
The Hubble Space Telescope has captured rare and detailed images of the interstellar comet 3I/ATLAS, revealing two opposing jets of gas and dust that alternate in brightness in a puzzling rhythmic pattern. This phenomenon, never before observed in such a form, has raised new questions about how interstellar......
Astronomers are preparing for a remarkable cosmic encounter as interstellar comet 3I/ATLAS makes its closest pass to Earth on December 19. The celestial visitor, originating from beyond the solar system, will come no nearer than 167 million miles from the planet roughly twice the distance between the......
The United Nations has confirmed that interstellar comet 3I/ATLAS is at the centre of a full scale planetary defence exercise designed to test how well the world can respond to a genuine cosmic threat in the future. Aimed at space policy analysts, planetary defence specialists and readers who follow......
Harvard astrophysicist Avi Loeb is urging NASA to release high-resolution images of the interstellar comet 3I/ATLAS, claiming that the Manhattan-sized object might be extraterrestrial technology rather than a natural visitor from another star system. This demand has reignited debate surrounding Loeb’s......
The interstellar comet 3I/ATLAS, the third confirmed visitor from beyond our solar system, has astonished scientists with its unusually high levels of carbon dioxide and unexpected activity as it approaches the Sun. Multiple NASA missions and international observatories are closely studying its composition......
