Earth’s global magnetic field likely dates back billions of years and is a barrier against cosmic radiation. What roles has it played in the planet’s biosphere?Read More »Planetary Sciences
Models link the variety of crater shapes expected on (16) Psyche with the interior structure of this unique asteroid, in preparation for the arrival of the Psyche probe in 2026.Read More »Planetary Sciences
Scientists tested whether a classic technique could detect subsurface oceans on the moons of Uranus. In this scenario, the planet’s oddball magnetic field offers a big advantage.Read More »Planetary Sciences
With no atmosphere in the way, measurements of the planet’s surface temperature are the first observational constraints on mantle convection models for an exoplanet.Read More »
Terrestrial caves offer scientific and engineering insights and serve as testing grounds for future forays by humans and robots into caves on other worlds.Read More »
Aliens spying on us from afar is a common science fiction trope. Soon we might know what E.T. would see through a telescope. And that information could help identify other Earth-like planets. Read More »Planetary Sciences
While the seas were still churning from the impact and the seawater temperatures were high due to the hydrothermal activity, life was reestablishing itself inside the crater.Read More »Geology & Geophysics
By modeling over 4 billion years of the Moon’s impact history, scientists estimate that the lunar poles may harbor billions of metric tons of subsurface ice. Read More »
