Earth’s magnetic field is like a powerful trap. It lures electrically charged particles in space, near our planet, and snares them in an invisible, doughnut-shaped pen around Earth known as the ring current.

Mars is not what it used to be. Once warm, watery, and blanketed by a thick atmosphere, today the Red Planet is cold, dry, and draped by a thin atmospheric veil. The main culprit is a relentless stream of particles from the Sun, known as the solar wind. Over billions of years, the solar wind has stripped away […]

This story is also available in Spanish. A new NASA mission will capture images of Earth’s invisible “halo,” the faint light given off by our planet’s outermost atmospheric layer, the exosphere, as it morphs and changes in response to the Sun. Understanding the physics of the exosphere is a key step toward forecasting dangerous conditions […]

The Sun
The NASA-ESA Solar and Heliospheric Observatory (SOHO) spacecraft captured this extreme ultraviolet wavelength image of the Sun on Feb. 24, 2015, during a three-hour period in which our closest star blew out a coronal mass ejection along with part of a solar filament. While some of the strands fell back into the Sun, a substantial […]
