Solar prominences. Close-up of the surface of the Sun,showing eruptions of ionized plasma known as solar prominences. These consist of plasma (ionised gas) at a much cooler temperature than that found in the corona,the Sun's atmosphere. This makes the prominence visible as a darker feature as it erupts from the layer of the Sun known as the photosphere. Solar prominences can be thousands of kilometres in length and last for days or months. These solar prominences were imaged with a hydrogen alpha 0.6-angstrom filter on 16 December 2006 | |
