This illustration, updated as of December 2020, depicts NASA’s Europa Clipper spacecraft. The mission, targeting a 2024 launch, will investigate whether Jupiter’s moon Europa and…
Model for the Earth’s core: Heidelberg researchers verify presence of solar noble gases in metal of an iron meteorite. High-precision noble gas analyses indicate that…
Nitrogen-bearing, Earth-like planets can be formed if their feedstock material grows quickly to around moon- and Mars-sized planetary embryos before separating into core-mantle-crust-atmosphere, according to…
Accelerated melt. Credit: TiPES/HP An analysis of the melt situation on the Central-Western Greenland ice sheet reveals clear signs of tipping. Data from the Jakobshavn…
