ESO's VLT has for the first time measured the chemical composition of an extrasolar comet, 3I/ATLAS. Findings published in Nature Astronomy suggest the comet's host star is very ancient.

New evidence from astronomers suggests that the recently discovered interstellar comet 3I/ATLAS is almost as old as the universe itself, originating from a region and time long before our solar system formed.

A new study suggests that the interstellar comet 3I/ATLAS could be almost three times older than the solar system, originating from the early period of the Milky Way. Its unique chemical signature does not match any known celestial body.

Scientists have estimated the interstellar comet 3I/ATLAS, which was previously speculated to be an alien spaceship, to be approximately 7 billion years old.

The NASA James Webb Space Telescope has discovered methane and an unusual abundance of carbon dioxide deep within the interstellar comet 3I/ATLAS.

A new study suggests that Comet 3I/ATLAS, the third confirmed interstellar visitor to our solar system, may be up to 11 billion years old, possibly forming in an isolated part of the galaxy.

New estimates based on isotopic composition suggest that the interstellar comet 3I/ATLAS could be between 10 and 12 billion years old.

The European Space Agency's Juice probe has captured a highly detailed image of the interstellar comet 3I/ATLAS as it passed through the Solar System, actively releasing dust and gas.

The interstellar comet 3I/ATLAS, one of three such objects discovered, has been extensively studied, with new research now estimating the age of its ice.

Scientists have determined that Neanderthals did not disappear due to inbreeding, identified the recently discovered interstellar comet 3I/ATLAS as being as old as the universe, and stated that some of Max Planck's articles were mistakenly attributed.

A new study published in Nature reveals that the interstellar comet 3I/ATLAS is nearly as old as the universe, estimated to be up to 12 billion years old. This discovery provides significant insights into the early cosmos.

Scientists have conducted a second wave of observations since December 2025, allowing them to better characterize the chemical composition of the interstellar comet '3I/Atlas'. The findings suggest it formed in an extremely cold environment beyond our Solar System.

The third interstellar visitor to our solar system, comet 3I/Atlas, has presented new surprises with its composition. Scientists report that its makeup differs significantly from all known comets originating within our solar system.

Astronomers are surprised by the discovery that interstellar comet 3I/ATLAS contains a significant amount of alcohol, prompting new questions about its unique chemistry and potential implications for understanding planet formation.

Scientists have uncovered the unique chemical composition of interstellar comet 3I/ATLAS, developed a method to grow millions of cancer-killing cells from a single stem cell, and suggested that procrastination might be linked to high creative potential.

Astronomers are baffled by 3I/ATLAS, the third and brightest interstellar visitor ever detected in our Solar System. Discovered in July 2025, this object offers a rare chance to study a body formed outside our galaxy.

Scientists suggest that the interstellar comet 3I/Atlas, which passed by the Sun last year, could be the oldest object observed in our Solar System, potentially three times older than the system itself.

Research suggests an interstellar comet that recently passed the sun could be nearly three times older than our solar system, making it potentially the oldest object observed within it.

Harvard astrophysicist Avi Loeb suggests that an alien 'gardener' might have directed the interstellar comet 3I/ATLAS towards Earth, despite its current departure from our solar system.

New research suggests that the interstellar object 3I/ATLAS originated from a region significantly colder than our solar system, providing insights into its formation and journey.

The JUICE spacecraft, en route to Jupiter, has discovered that the interstellar comet 3I/ATLAS is releasing tons of water into space every second.

Astronomers studying the interstellar comet 3I/ATLAS have discovered it is unusually rich in methanol, a chemical signature that could provide insights into how planets and icy bodies form around other stars.
