Dynamics of ocean worlds likely controlled by their rotation

Discovering that many of the large moons in the outer solar system may host significant subsurface oceans of liquid water has been a key advance in planetary science. These moons represent some of the most promising habitats ...

Exploring eruptions from the Sun

In our solar system, solar flares and coronal mass ejections (CME) are the most spectacular eruptive activities. Large solar flares and CMEs may bring us disastrous space weather, destroy our satellite and navigation system, ...

New instrument to measure atmospheric ammonia

In the past decades, intensive human agricultural activities have caused a significant increase in ammonia (NH3) emissions to the atmosphere, which have led to serious environmental and public health problems.

Was the moon magnetized by impact plasmas?

The moon, Mercury and many meteorite parent bodies contain a magnetized crust, which is commonly credited to an ancient core dynamo. A longstanding alternative hypothesis suggests the amplification of the interplanetary magnetic ...
