NASA | Voyager Finds Magnetic Bubbles at Solar System's Edge
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 axis in...

NASA's MMS Captures Magnetic Reconnection in Action
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...

NASA | IBEX Provides First View of the Solar System's Tail
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 that...

Solar Wind at Martian Moon Could Impact Future Missions
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 their orbits....

Exploring the Wonders of Aurora
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...

NASA | Mars Atmosphere Loss: Sputtering
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.

NASA | Investigating the Martian Atmosphere
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 have been...

NASA | IBEX | What are the Boundaries of our Solar System?
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...
