New research suggests that understanding factors common to celestial light shows over Earth, Saturn and Jupiter can help predict risky space weather.. These particles travel down magnetic field lines, interacting with atoms in our atmosphere and causing them to emit light. The bombardment of charged particles from the sun doesn't just generate beautiful light shows over Earth, though.
Yet, despite these differences, a team of scientists from the Department of Earth Sciences at The University of Hong Kong thinks a unified understanding of how the solar wind drives auroral displays over various planets could lead to important practical applications. This unity can help us monitor, predict and explore the
A composite image of auroras on Jupiter, taken using the Hubble Space Telescope's Imaging Spectrograph.To study planetary magnetic field dynamics, the team looked at the way electromagnetic fields like those of Earth's magnetosphere interact with electrically conducting fluids that take the role of charged particles in solar winds. Modeling this in three dimensions helped them to better understand how auroras over different planets take on different shapes or"morphologies.

Discovery of biomarkers in space—conditions on Saturn's moon Enceladus simulated in the laboratoryIn 2018, very large organic molecules were discovered in ice particles on Saturn's moon Enceladus. It is still unclear whether they indicate the existence of life or were created in some other way. A recent study could help to answer this question.
