ILLUSTRATION: NICOLAS SARTER/IPGP InSight and Perseverance have sent back unprecedented data on everything from marsquakes to the Red Planet’s inner layers. WHILE HUMANS HAVE been struggling to control the Covid-19 pandemic, baking in record heat, and trying to figure out how not to run out of water, our spacecraft on Mars have been enjoying a […]

NASA’s Juno Mission observed pulsating electromagnetic ion cyclotron waves in Jupiter’s dawn magnetosphere that periodically expel energetic heavy ions into the atmosphere, producing stunning X-ray pulsations as captured by ESA XMM-Newton.

This processed image of Io by New Horizons shows the 290-kilometer-high (180-mile-high) plume of the volcano Tvashtar near Io’s north pole. Also visible is the Prometheus volcano’s much smaller plume in the 9 o’clock direction. The top of the Masubi volcano’s plume appears as an irregular bright patch near the […]

Ganymede flyby.

On June 7, 2021, NASA’s Juno spacecraft flew closer to Jupiter’s ice-encrusted moon Ganymede than any […]

Astrophysicists at LMU have calculated that such systems could harbor sufficient […]

New research shows the sun’s magnetic field drew iron toward the center of our solar system as the planets formed. That explains why Mercury, which is closest to the sun has a bigger, denser, iron core relative to its outer layers than the other rocky planets like Earth and Mars. […]

This image is a composite of data from NASA’s Magellan spacecraft and Pioneer Venus Orbiter.

In the latest announcement from NASA’s solar system exploration program, two missions […]

The EnVision mission to Venus will explore why Earth’s closest neighbor is so different. Credit: NASA / JAXA / ISAS / DARTS / Damia Bouic / VR2Planets EnVision will be ESA’s next Venus orbiter, providing a holistic view of the planet from its inner core to upper atmosphere to determine […]
