Check out this picture of our Sun: It is a picture of a solar prominence, a large bright feature extending outward from the Sun's surface. Interestingly, the hot plasma structure is many times the size of planet Earth. In fact the largest ever prominence was some 350,000 km long - 28 times the diameter of the Earth. The mass contained within a prominence is typically of the order of 100 billion tonnes of material - WOW! |
