Protocols for the Moon and Mars, human exploration, ocean worlds, and the private sector are all due for a major overhaul.Read More »Planetary Sciences
Future space missions will further our knowledge of tidal heating and orbital resonances, processes thought to create spectacular volcanism and oceans of magma or water on other worlds.Read More »Space Science & Space Physics
The first in situ measurement of the pressure at the edge of the solar system reveals that there’s still a lot we don’t know about what sets the size of the heliosphere.Read More »Planetary Sciences
A first look at the chemical composition of the interstellar comet Borisov reveals ingredients that look a lot like those found in solar system comets. That’s not likely to last very long.Read More »Planetary Sciences
A new model is the first to simultaneously explain many of the moons’ characteristics, including their mass, orbits, and icy compositionRead More »Biogeosciences
A new theory suggests that nitrogenase from cyanobacteria could be the reason oxygen levels remained low after the Great Oxidation Event.Read More »Planetary Sciences
Research suggests that the spherical structures, smaller than grains of sand, may be microtektites, but additional investigations are needed to verify their identity. Read More »Planetary Sciences
The first in-situ ion observations from NASA’s Juno spacecraft reveal the surprising, simultaneous presence of cold protons and hot oxygen and sulfur ions in the high-latitude ionosphere of Jupiter.Read More »Space Science & Space Physics
A new tool for tracking coronal mass ejections away from the Sun opens a path toward more accurate warnings for operators who have to cope with adverse space weather.Read More »
