ALMA observed water in Halley-type comet 12P/Pons-Brooks that was similar to Earth’s oceans, indicating the role of comets in ...

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

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

It feels like there have been staggering science stories emerging every other day recently, all of which have blown our tiny little minds. First, there was the discovery of a terrifying black hole ...

Chemical profiling traces the source of water in one of the brightest known comets to keep returning to the Solar System.

For starters, despite looking like a shapeless solid, ice is actually made up of multiple nanoscopic crystals, all of which are only a few billionths of a meter across, if that.

A new analysis of ancient grains of crystal embedded in rock from the Australian outback suggests Earth had dry land and fresh water some 4 billion years ago — a time when scientists had thought ...

Water is constantly leaking through Earth's crust and toward the outer core as tectonic plates subduct under one another, while magma rises via a similar pathway in the opposite direction.

Water leaking into the Earth may be wrapping the core in crystals, a study has suggested. The study may help explain a weird area in the outer core that has long puzzled scientists.
