NASA's Perseverance Mars rover may have captured an image of interstellar comet 3I/ATLAS streaking across the sky above the Red Planet.
ESA is making use of spacecraft originally dedicated to its Mars and Jupiter missions to track comet 3I/ATLAS as it continues its journey through our solar system
Astronomers say that mysterious interstellar visitors like 'Oumuamua and 3I/ATLAS are the most common large bodies in the Milky Way — and our best chance to study other planetary systems.
This quiz invites you to chase comets through time and space, from ancient omens to modern scientific marvels.
The comet will come closest to Earth on Oct. 20. There's hope that it may become bright enough to glimpse with the naked eye.
The interstellar visitor appears to have a lot in common with its solar system brethren.
The interstellar comet 3I/ATLAS will zoom past Mars in October 2025, and ESA's Mars orbiters will attempt to image and analyze the object during the encounter.
"Once these objects get too faint to see, they will never be seen again,"
While observing the Halley-type comet 12P/Pons-Brooks with ALMA and NASA's Infrared Telescope Facility, researchers determined that the comet's water is strikingly similar to the water on Earth.
