A team of researchers led by Costanza Argiroffi, an astronomer at the University of Palermo in Italy, has found evidence of a coronal mass ejection (CME) from a star that was not our sun—the first ever observed. They reported ...
The first images from the Solar Ultraviolet Imager or SUVI instrument aboard NOAA's GOES-16 satellite have been successful, capturing a large coronal hole on Jan. 29, 2017.
