Water origins

NASA’s SPHEREx mission will survey the Milky Way galaxy looking for water ice and other key ingredients for life. In the search for these frozen compounds, the mission will focus on molecular clouds — collections of gas and dust in space — like this one imaged by the agency’s James Webb Space Telescope.

NASA’s New Space Telescope to Hunt for Ice That Could Harbor Life’s Origins

Earth’s water did not come from melted meteorites, according to a new study that analyzed melted meteorites that had been floating around in space since the solar system’s formation four and a half billion years ago. These meteorites had extremely low water content, regardless of their origin in the outer or inner solar system, ruling them out as the primary source of Earth’s water. The dashed white line in the attached illustration is the boundary with the outer solar system showing material transport from the outer solar system to the inner solar system.
