(Phys.org)—At the onset of a series of coronal mass ejections (CMEs) on August 20, 2012, this bulbous CME certainly resembled a light bulb. It has the thin outer edge and a bright, glowing core at its center. CMEs are often bulbous, but it has been years since we've seen one with the elements (pun intended) of a light bulb.
