The mighty Yukon River and nearby lakes appear in red in this image produced using data recorded on June 18, 2023, by the international Surface Water and Ocean Topography (SWOT) satellite as it passed over Alaska.

This animation, created in 2012, shows the increasing clarity and detail of measurements of sea height made by successive satellite altimeters launched by NASA and other agencies over the past four decades.

Using NASA Herschel Space Observatory, astronomers have discovered that comet Hartley 2 possesses a ratio of heavy water to light, or normal, water that matches what found in Earth oceans.

This image shows differences in atmospheric water vapor relative to a normal average year in the Earth upper troposphere about 10 kilometers 6 miles above the surface.
