New analyses of oxygen isotopes reveal terrestrial and lunar rocks aren’t as similar as previously thought, potentially changing the way we think the Moon formed.Read More »
The gaseous atmospheres of giant planets may evaporate and accrete onto the dense surfaces of white dwarfs, providing astronomers a new way to detect hidden exoplanets.Read More »Planetary Sciences
When the lander MASCOT, carried by Hayabusa2, touched down on asteroid Ryugu, it did not detect a magnetic field, even though meteorites that are spectroscopically similar to Ryugu have trace of one.Read More »Planetary Sciences
