Jun 17, 2023 · New research suggests our planet was born from a rapid accumulation of tiny pebbles and icy fragments in just a few million years.

Aug 27, 2020 · Water is abundant in space but it was thought that Earth was dry when it formed; A new study shows that meteorite rocks of the type that built the Earth contain the building blocks of water

Feb 23, 2024 · Similar observations of such planetary nurseries by the James Webb Space Telescope (JWST) are revealing new details about how water finds its way into rocky worlds.

Dec 5, 2024 · Scientists have gathered new evidence to suggest icy comets indeed brought water to Earth, long ago.

5 days ago · The team of researchers developed a new model for the origin of water on Earth that incorporates factors like water absorption on primordial dust grains, contributions from asteroid and planetary embryos, and water from comets. The model also accounts for the time of water delivery based on evidence from Earth’s geological record.

Sep 25, 2014 · The results suggest that up to 30 to 50 percent of Earth's ocean water and perhaps 60 to 100 percent of the water on comets originally formed in interstellar space, before the sun was born.

Feb 17, 2025 · Studies of ancient terrestrial rocks suggest liquid water existed on Earth as early as 100 million years after the Sun’s formation–practically “immediately” on an astrophysical timescale. This...

Mar 11, 2023 · Sleuthing out evidence that our solar system's water came from interstellar space has been elusive. But the protostar V883 Orionis finally provided an exciting opportunity. Astronomers use radio...

Launched in 2002, a pair of identical satellites that make up NASA’s Gravity Recovery And Climate Experiment (GRACE) are tackling the problem in an unexpected way: they are weighing Earth’s fresh water from space.

Dec 14, 2022 · A new mission from NASA's Jet Propulsion Laboratory will study water on Earth from space, ushering in a new era in the study of climate change.
