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 […]

NASA Analysis Shows Sun’s Activity Ramping Up

It looked like the Sun was heading toward a historic lull in activity. That trend flipped in 2008, according to new research. The Sun has become increasingly active since 2008, a new NASA study shows. Solar activity is known to fluctuate in cycles of 11 years, but there are longer-term variations that can last decades. […]

NASA Research Shows Path Toward Protocells on Titan

NASA research has shown that cell-like compartments called vesicles could form naturally in the lakes of Saturn’s moon Titan. Titan is the only world apart from Earth that is known to have liquid on its surface. However, Titan’s lakes and seas are not filled with water. Instead, they contain liquid hydrocarbons like ethane and methane.  […]

NASA’s Curiosity Mars Rover Starts Unpacking Boxwork Formations

The rover recently drilled a sample from a new region with features that could reveal whether Mars’ subsurface once provided an environment suitable for life. New images from NASA’s Curiosity Mars rover show the first close-up views of a region scientists had previously observed only from orbit. The images and data being collected are already […]

NASA Launching Rockets Into Radio-Disrupting Clouds

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.

NASA’s Dragonfly Mission Sets Sights on Titan’s Mysteries

When it descends through the thick golden haze on Saturn’s moon Titan, NASA’s Dragonfly rotorcraft will find eerily familiar terrain. Dunes wrap around Titan’s equator. Clouds drift across its skies. Rain drizzles. Rivers flow, forming canyons, lakes and seas.  But not everything is as familiar as it seems.
