NASA’s ESCAPADE Ready to Study Space Weather from Earth to Mars

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 […]

New NASA Mission to Reveal Earth’s Invisible ‘Halo’

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 […]

A Brief Outburst

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 […]

NASA Missions Help Explain, Predict Severity of Solar Storms

An unexpectedly strong solar storm rocked our planet on April 23, 2023, sparking auroras as far south as southern Texas in the U.S. and taking the world by surprise.  Two days earlier, the Sun blasted a coronal mass ejection (CME) — a cloud of energetic particles, magnetic fields, and solar material — toward Earth. Space scientists […]
