Giant holes have emerged on the Sun!

Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! Coronal holes are not unusual, but perhaps what is unusual is that 2 massive ones have just appeared, pointing straight at us. What exactly are these phenomena and should we be worried? Let me explain!
