Some northern U.S. states might have an opportunity to see the northern lights Friday, and a recent coronal mass ejection will likely bring the phenomenon to more areas this weekend, according to ...

NASA’s PUNCH mission tracks coronal mass ejections from the Sun to Earth for the first time, offering new insight into space weather.

The NOAA defines a coronal mass ejection as “large expulsions of plasma and magnetic field from the Sun’s corona.” Authorities said conditions will likely intensify as the progression continues.
