Detecting Exoplanet Magnetic Fields From The Moon

Universe Today - Thu, 08/21/2025 - 8:41pm

Exoplanets with and without a magnetic field are predicted to form, behave, and evolve very differently. In order to understand the exoplanet population, and to make progress understanding habitability, astronomers need to understand and constrain exoplanets' magnetic fields. Detecting them may best be done from the Moon.

How Did Jupiter's Galilean Moons Form?

Universe Today - Thu, 08/21/2025 - 8:41pm

We already know a decent amount about how planets form, but moon formation is another process entirely, and one we’re not as familiar with. Scientists think they understand how the most important Moon in our solar system (our own) formed, but its violent birth is not the norm, and can’t explain larger moon systems like the Galilean moons around Jupiter. A new book chapter (which was also released as a pre-print paper) from Yuhito Shibaike and Yann Alibert from the University of Bern discusses the differing ideas surrounding the formation of large moon systems, especially the Galileans, and how we might someday be able to differentiate them.

A Cosmic Noon Puzzle: Why Did Cosmic Noon Galaxies Emit So Many Cosmic Rays?

Universe Today - Thu, 08/21/2025 - 8:41pm

The Universe's early galaxies were engulfed in halos of high-energy cosmic rays. It's likely because they had tangled and turbulent magnetic fields. These fields accelerate cosmic rays to higher energies.
