Alien hunting Harvard astronomer Avi Loeb continues to rail against the idea that our newest interstellar is merely a comet.

Our new results provide the strongest evidence yet that at least some Halley-type comets carried water with the same isotopic ...

Researchers found that Comet 12P/Pons-Brooks contains water matching Earth’s oceans. The comet, nicknamed the “devil comet,” was studied using advanced observatories in Chile and Hawaii.

An interstellar comet spotted by NASA is headed for our solar system, showing up near Earth later this year, but it's another ...

Comet 12P/Pons Brooks shows a D/H water ratio matching Earth’s oceans, revealed through ALMA and NASA IRTF observations.

"We should put all possibilities on the table that it's a rock, a comet, or something else until we get the evidence, the ...

New research has uncovered compelling evidence that water from a comet is strikingly similar to that found in Earth's oceans, ...

These strange objects could explain how water arrived on Earth, but may also be a previously unrecognised threat to our ...
