New research has uncovered compelling evidence that water from a comet is strikingly similar to that found in Earth's oceans, offering fresh support for the idea that comets may have played a ...

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

While observing the Halley-type comet 12P/Pons-Brooks with ALMA and NASA's Infrared Telescope Facility, researchers ...

Water on the Devil Comet matches Earth’s, supporting the idea that comet impacts delivered life-giving water to young Earth.

In terms of speed, the comet is still holding that record. The interstellar object has a larger velocity than some of the Solar System comets, including Halley’s Comet at closest approach to the ...
