11Solar prominence — with images of Jupiter and Earth for size comparison. Solar prominence video clip (high resolution) A prominence is a large, bright feature extending outward from the Sun …
12Coronal hole — Coronal holes are areas where the Sun s corona is darker, colder, and has lower density plasma than average. These were found when X ray telescopes in the Skylab mission were flown above the Earth s atmosphere to reveal the structure of the… …
13Solar telescope — The Swedish 1 m Solar Telescope at Roque de los Muchachos Observatory, La Palma in the Canary Islands. A solar telescope is a special purpose telescope used to observe the Sun. Solar telescopes usually detect light with wavelengths in, or not far …
14Moreton wave — Animation of a Moreton wave which occurred on December 6, 2006 A Moreton wave is the chromospheric signature of a large scale solar coronal shock wave. Described as a kind of solar tsunami ,[1] they are generated by solar flares. They are named… …
15Coronal loop — Typical coronal loops observed by TRACE Coronal loops form the basic structure of the lower corona and transition region of the Sun. These highly structured and elegant loops are a direct consequence of the twisted solar magnetic flux within the… …

18Coronal radiative losses — In astronomy and in astrophysics, for radiative losses of the solar corona, it is meant the energy flux irradiated from the external atmosphere of the Sun (traditionally divided into chromosphere, transition region and corona), and, in particular …
19Nanoflares — A nanoflare is a very small solar flare which happens in the corona, the external atmosphere of the Sun. The hypothesis of microflares as a possible explanation of the coronal heating was first suggested by Gold [1] and then later developed by… …
20Outline of astronomy — Mauna Kea in Hawaii is one of the world s premier observatory sites. Pictured is the W. M. Keck Observatory, an optical interferometer. The following outline is provided as an overview of and topical guide to astronomy: Astronomy – studies the… …
