Does Ganymede Look Young?

On June 7, 2021, NASA’s Juno spacecraft flew closer to Jupiter’s moon Ganymede than any spacecraft had ever before. Ganymede is the largest moon in the Solar System—a body larger than the planet Mercury. Its frozen surface holds interest as a distant water source. Analysts still ponder three unique features of Ganymede, one of which they’re now seeing for the first time.


Venus Likely Geologically Active

In June 2021, researchers used radar images from the Magellan spacecraft to show that crustal blocks on the Venusian surface jostle against one another like blocks of pack ice on a lake.1 This is just one of multiple lines of evidence that Venus is geologically active, and thus looks younger than expected.2
 

Can Asteroids Select Life?

A recent study published in Science claims that an asteroid caused new forms of plants to evolve.1-3 But can an asteroid really be responsible for selecting new forms of life?


Greenland: Ice-Free Not That Long Ago

Preserved leaves and twigs in a tube of soil show Greenland was largely ice-free in the relatively recent past.1 This discovery has important implications both for the ages that uniformitarian scientists assign to the deep ice cores and the global warming debate.


Reminder: Saturn's Moon Titan Really Looks Young

Scientists led by Valerio Poggiali of Cornell University’s Center for Astrophysics and Planetary Science have used Cassini spacecraft data to learn a little more about Saturn’s largest moon Titan.
