Groundbreaking rodent research shows that galactic cosmic rays and simulated weightlessness cause lingering cardiovascular remodeling and immune shifts months after exposure. Venturing beyond low Earth orbit presents profound biological challenges that...

from a coronal hole. Both phenomena inject energetic particles into interplanetary space, and when they encounter Earth’s magnetosphere they spark the geomagnetic activity that powers the aurora. Forecasts place the planetary Kp index near 5.7, a level...

to as coronal mass ejections, into the interplanetary medium. When these streams of solar material collide with the Earth’s magnetosphere, they are funneled toward the planet’s polar regions. Upon reaching the upper atmosphere, these particles energize...

radio signatures are linked to streams of charged particles that can traverse the Solar System and interact with Earth’s magnetosphere. By charting the sources of these emissions with unprecedented accuracy, researchers aim to clarify how particles are...

Astronomers have detected auroral radio bursts from a gas giant 63 light-years away, enabling the first direct measurement of an exoplanet’s magnetic field. Astronomers have achieved a breakthrough in planetary science by detecting radio emissions...

Scientists reveal the solar wind stopped weakening in 2008 and has been strengthening since, reshaping space weather and the heliosphere. For more than two decades up to 2008, multiple studies reported a gradual weakening of the solar wind and its...

energy. This process, called magnetic reconnection, is known from: Solar flares in our own Sun. Magnetic storms in Earth’s magnetosphere. In NGC 3783, something similar appears to be happening much closer to a supermassive black hole. Magnetic...
