Turbulence, magnetic fields, and feedback from young stars interact in complex ways to set stellar masses and rates. Multi-scale simulations and high-resolution observations with radio and infrared telescopes can help disentangle these effects.

Gas, dust, magnetic fields, and cosmic rays interact across scales, but many parameters are poorly measured. Multi-band surveys and simulation campaigns can connect small-scale physics with galactic evolution.

Magnetic storms and particle fluxes shape space weather and radiation hazards but are hard to predict. Better in situ measurements and coupled simulations can improve forecasts.

Magnetically confined plasmas exhibit instabilities and transport phenomena that limit performance. Better diagnostics and simulation tools can improve reactor design.

These fields affect cosmic-ray propagation and structure formation but are hard to measure. Faraday rotation surveys and gamma-ray observations can constrain them.

Deep flows and core structure are difficult to infer. Gravity and magnetic measurements from orbiters can improve models.

Long-duration missions to Mars risk irreversible DNA damage, cognitive decline, and cancer in astronauts. Lightweight, high-efficiency passive shielding or active electromagnetic deflectors remain undeveloped.

The Coronal Heating Problem violates intuition: the outer solar atmosphere reaches millions of degrees while the surface is ~5,500°C. Solving this requires understanding magnetic reconnection and Alfvén wave dissipation mechanisms.

Solar flares release massive kinetic and radiation energy, disrupting global High-Frequency radio and GPS signals. Micro-scale magnetic reconnection models are needed to predict flares hours before they burst.

As microchips shrink, energetic cosmic particles flip memory bits more frequently, freezing flight computers. Ultra-reliable fault-tolerant voting architectures and magnetic RAM must be deployed across satellite buses.

The solar magnetic dynamo flip drives the solar activity cycle, but we cannot accurately predict cycle strength decades in advance. High-resolution solar interior magnetohydrodynamic models are required.

A large enough solar storm could damage transformers and electronics across entire continents, and current models can't precisely predict which systems would fail. Better modeling could guide smarter infrastructure protection investment.

Earth's magnetic field protects us from solar radiation, but the dynamo process that generates it deep underground is still only partly understood. This matters for predicting how long that protection will last.

Outside Earth's magnetic field, cosmic radiation raises cancer risk and can damage the brain and body over time. This is one of the biggest blockers to sending humans to Mars safely.
