Sounding rocket mission to offer snapshot of sun's magnetic field

Measuring a magnetic field isn't so hard if you're inside of it. Measuring a magnetic field remotely—whether from across a room, across a country, or 93 million miles away—is an entirely different story. But that's exactly ...

Scientists propose new formation mechanism for solar coronal rain

Rain is a common phenomenon on Earth. There is a similar phenomenon on the Sun, called coronal rain. It is related to the coronal heating and magnetic field, and plays a fundamental role in the mass cycle between the hot, ...

Space missions are building up a detailed map of the sun's magnetic field

Solar physicists have been having a field day of late. A variety of missions have been staring at the sun more intently ever before (please don't try it at home). From the Parker Solar Probe to the Solar Orbiter, we are constantly ...

Astrophysicist's 2004 theory confirmed: Why the Sun's composition varies

About 17 years ago, J. Martin Laming, an astrophysicist at the U.S. Naval Research Laboratory, theorized why the chemical composition of the Sun's tenuous outermost layer differs from that lower down. His theory has recently ...
