Even though our Sun shines bright in the sky, it is shrouded in mystery. In this episode, we'll sit down with scientists working to get us closer to the Sun than ever before.

Scientists have long suspected the solar wind of stripping the Martian atmosphere into space, a process that may have turned Mars from a blue world early in its history into the red planet that we see today. In 2014, NASA's...

A great magnetic bubble surrounds the solar system as it cruises through the galaxy. The sun pumps the inside of the bubble full of solar particles that stream out to the edge until they collide with the material that fills the...

Launched in 2007, NASA's five THEMIS spacecraft have now successfully completed their 2 year mission to determine the cause of geomagnetic substorms. Because they are continuing to work perfectly, NASA is re-directing the outermost...

This year’s 12th Annual Goddard Film Festival will highlight Goddard’s...

The sun's magnetic field spins opposite directions on the north and south poles. These oppositely pointing magnetic fields are separated by a layer of current called the heliospheric current sheet. Due to the tilt of the magnetic...

Like sending sensors up into a hurricane, NASA has flown four spacecraft through an invisible maelstrom in space, called magnetic reconnection. Magnetic reconnection is one of the prime drivers of space radiation and so it is a key...

It's been 50 years since humans walked on the moon. Now NASA is planning to return, this time to stay. What will future lunar missions look like? Why do we go back at all?

NASA's Interstellar Boundary Explorer, or IBEX, recently mapped the boundaries of the solar system's tail, called the heliotail. By combining observations from the first three years of IBEX imagery, scientists have mapped out a tail...

Technology can take you to unexpected places. The MarCO cubesats, flying towards Mars with InSight, are breaking new ground on how far these small satellites can go.

Mars has two moons, Phobos and Deimos. Both are small, airless bodies with irregular shapes. Because they lack protective atmospheres and magnetospheres, Phobos and Deimos are directly exposed to the solar wind for part of...

In this video, we explore the fascinating natural phenomenon of auroras, where swirling lights appear in the sky. We learn about the science behind auroras, how they are formed near the Earth's polar regions, and the interaction between...

Summer 2019, NASA's Space Environment Testbeds, or SET, will launch on its mission to study how to better protect satellites in space. SET studies the very nature of space itself -- which isn't completely...

International Observe the Moon Night 2020 welcomed participants from all 7 continents, 103 countries, all 50 U. S. states, Guam, Puerto Rico, the U. S. Virgin Islands, and Washington, D.C. Hear from...

What NASA calls its 'Heliophysics Observatory' is an impressive fleet of spacecraft designed (often with international partnership) to study the relationship between the Sun, Earth, and Solar System. Flying in an array of trajectories...

NASA's STEREO spacecraft and new data processing techniques have succeeded in tracking space weather events from their origin in the Sun's ultrahot corona to impact with the Earth 96 million miles away, resolving a 40-year...

Ancient riverbeds, crater lakes and flood channels all attest to Mars's warm, watery past. So how did the Red Planet evolve from a once hospitable world into the cold, dry desert that we see today? One possibility is that Mars lost...

NASA's Van Allen Probes revealed a new radiation belt around Earth



The Van Allen Probes mission discovered a previously unknown third radiation belt around Earth, revealing the existence of unexpected structures...

How did Mars, a once wet planet, lose its early atmosphere? One possibility is through a process called "sputtering," in which atoms are knocked away from the atmosphere due to impacts with energetic particles.<b<b<br/>r/>r/>

The Martian surface bears ample evidence of flowing water in its youth, from crater lakes and riverbeds to minerals that only form in water. But today Mars is cold and dry, and scientists think that the loss of Mars' water may...

IBEX is a new NASA mission that will study the interaction between the solar wind and the material beyond our Solar System called the interstellar medium. The solar wind flowing out of the sun inflates a bubble that we call the...

Every object, planet or person traveling through space has to contend with the Sun's damaging radiation -- and the Moon has the scars to prove it.



Research using data from NASA's ARTEMIS mission — short for...

NASA's Parker Solar Probe mission has returned unprecedented data from near the Sun, culminating in new discoveries published on Dec. 4, 2019, in the journal Nature. Among the findings are new...
