SUNSET: 
Scientists Map the Sun’s Magnetic “Surface”
Where does the Sun end and the solar wind begin? Scientists have mapped the dynamic magnetic edge that bounds our star.
European Solar Orbiter Traces Origin of Solar Wind
Using the Solar Orbiter, scientists think they’ve pinpointed the locations near the Sun where particles are thrown into the solar wind.
Solar Probe Duo Unravel Solar Wind Mystery
For decades, scientists have wondered what accelerates solar wind particles as they move away from the Sun. New evidence points to magnetic switchbacks.
Caught in a Solar Storm on the Way to Mars
A chance alignment between Earth and a Mars-bound spacecraft has given us a rare glimpse at the motions of high-energy particles from the Sun.
Astronomers Map the Solar System's Edge in 3D
Collecting high-speed atoms has enabled researchers to trace the shape of our Sun’s protective bubble.
Scientists Recreate Space Weather of 400 Years Ago
Scientists are studying 400-year-old data to predict space weather in the coming decades — and it seems that future may hold fewer Northern Lights.
What is the solar wind?
The Sun’s outer atmosphere, the corona, is the source of the solar wind, a steady outflow of charged particles from the Sun.
