When is a planet not a planet? Where does helium rain? How can water be solid and liquid at the same time? For answers, scientists put common planetary materials under extreme pressure and watched what happened next.Read More »Space Science & Space Physics
A special collection in JGR Planets presents insights from a long-awaited global dust storm on Mars in 2018 that was closely scrutinized by five orbiting and two landed spacecraft.Read More »Space Science & Space Physics
The field of space weather forecasting could take cues from its Earthly counterpart to increase the reliability of models as well as warning times ahead of inbound solar storms.Read More »Planetary Sciences
Using topographic data, researchers have estimated the ages of water ice–containing craters near the Moon’s poles and ruled out volcanism as being a primary route for water delivery.Read More »Planetary Sciences
The first Jovian off-equator Energetic Neutral Atom viewings reveal distinct emissions from Jupiter and the orbits of Io and Europa: Energetic particle injections surprisingly occur inside Io’s orbit.Read More »Planetary Sciences
Thanks to spectacular high-resolution images from Hayabusa2, scientists can now better estimate how and when the asteroid Ryugu formed, how its orbit has changed over time, and what its surface looks like.Read More »Planetary Sciences
Fragmentos de un cometa probablemente golpearon la Tierra hace 12,800 años, y una pequeña aldea del Paleolítico en Siria podría haber sufrido el impacto.Read More »Geology & Geophysics
