The Sun

New research finds that solar storms vary in strength over surprisingly short distances, and the current network of sensors may not be enough to properly prepare for future outbursts.

Rarely seen orange auroras, which technically shouldn't exist, were recently photographed in the sky above Scotland after an explosive solar storm smashed into Earth.

A recent solar explosion that almost reached "X-class" status has hurled a massive coronal mass ejection toward Earth, which will likely hit our planet and trigger a geomagnetic storm on Dec. 1.

With the solar cycle set to peak earlier than predicted, the sun's corona should look its spectacular spiky best for April 8's total solar eclipse.

A massive sunspot region made up of at least six different sunspot groups has emerged on the sun's nearside. The "archipelago" of dark patches is spitting out solar storms at an alarming rate and Earth will soon be in the firing line.

Scientists have spotted an aurora signal caused by electrons accelerating through a sunspot on our star's surface for the first time ever.

New calculations suggest the sun is a few fractions of a percent smaller than previously estimated, and that could change how we study it.

Radio astronomers in California imaged the sun's scorching hot corona for the first time ever during a partial solar eclipse on Oct. 14.

A powerful explosion from the sun briefly opened up an enormous valley on the solar surface that was more than twice as wide as the contiguous U.S. and seven times longer than Earth.
