This article was updated to include the full range of dates from the SOHO image. Lee esta historia en español aquí. NASA is in the midst of an unprecedented solar system-wide observation campaign, turning its spacecraft and space telescopes to follow comet 3I/ATLAS, the third known interstellar object to pass through our solar system. Twelve […]

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 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 […]

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 […]

NASA is launching rockets from a remote Pacific island to study mysterious, high-altitude cloud-like structures that can disrupt critical communication systems. The mission, called Sporadic-E ElectroDynamics, or SEED, opens its three-week launch window from Kwajalein Atoll in the Marshall Islands on Friday, June 13.
