Astronomers have spotted something unusual in a comet passing through our Solar System. 3I/ATLAS, only the third confirmed interstellar visitor ever seen, appears to be stuffed with methanol, an ...
Scientists are scrambling to explain why interstellar visitor 3I/ATLAS is carrying life's chemical building blocks at concentrations never before seen, and it makes its final pass through our cosmic n ...
Harvard astrophysicist Avi Loeb says interstellar comet 3I/ATLAS likely comes from the Milky Way's disc, as astronomers ...
New data indicates Comet 3I/ATLAS is second only to C/2016 R2 in terms of methanol levels ever recorded in a comet within our solar system.

What an interstellar comet’s chemistry reveals about alien star systems
Comets are often treated as leftovers, but sometimes the leftovers become the primary focus. That is the case with 3I/ATLAS, only the third known interstellar object seen crossing the solar system, ...
Interstellar comet 3I/ATLAS has steadily been making its exit ever since it had a rendezvous at the end of October with the ...
Green Bank Telescope rules out alien signals in interstellar comet 3I/ATLAS after rigorous scientific deep search.

ALMA finds abundant methanol in interstellar comet 3I/ATLAS
Astronomers using the Atacama Large Millimeter/submillimeter Array in Chile have detected extraordinarily high levels of methanol in interstellar comet 3I/ATLAS, with methanol-to-hydrogen-cyanide ...
Add Yahoo as a preferred source to see more of our stories on Google. Those concerned that 3I/ATLAS' arrival to our solar system meant that some sort of alien invasion was imminent can breathe a sigh ...
New SETI research suggests space weather like solar winds could be interfering with alien radio signals, making them harder to detect.
Astronomers say that there are possible signs of life on Comet 67P, based on data from the European Space Agency's Philae Lander. The comet has features that indicate it may be home to alien life, ...
Scientists confirmed that the interstellar comet 3I/ATLAS, which passed closest to Earth in December 2025, showed no detectable technosignatures strong enough to suggest it is an alien spacecraft.
