If, like Earth, Proxima b has a molten core and an internal dynamo that produces a powerful magnetic field, its surface might be shielded from high doses of radiation. If, like Mars, it doesn’t ...

Astronomers used ALMA to observe Proxima Centauri and found frequent, intense flares that could destroy atmospheres of nearby ...

A small star just over four light-years from Earth has just made a very big statement. In a groundbreaking new study, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have ...

While Proxima b is thought to be in the "habitable zone ... develop on longer timescales if the world's atmosphere and magnetic field survive through the star's early, turbulence years.

The result is a magnetic field that is always jumbling and snapping ... to trace the properties of those particles." Though Proxima b may be nothing more than an irradiated rock, scientists ...

Once there [near Proxima b], the nanocraft could image any planets discovered in the system, test for magnetic fields and organic molecules, and send the data back to Earth in another laser beam. — ...

Magnetotactic bacteria synthesize magnetic iron nanominerals, which function as tiny compasses that allow the microbes to navigate using Earth's geomagnetic field. Earth's iron cycle is a very ...
