In solar physics and observation, an active region is a temporary feature in the Sun's atmosphere characterized by a strong and complex magnetic field. They are often associated with sunspots and are commonly the source of violent eruptions such as coronal mass ejections and solar flares . [ 1 ]
The solar transition region is a region of the Sun's atmosphere between the upper chromosphere and corona. [ 1 ] [ 2 ] It is important because it is the site of several unrelated but important transitions in the physics of the solar atmosphere:

The core is the only region of the Sun that produces an appreciable amount of thermal energy through fusion; 99% of the Sun's power is generated in the innermost 24% of its radius, and almost no fusion occurs beyond 30% of the radius. The rest of the Sun is heated by this energy as it is transferred outward through many successive layers ...
The antumbra (from the Latin ante "before" and umbra "shadow") is the region from which the occluding body appears entirely within the disc of the light source. An observer in this region experiences an annular eclipse, in which a bright ring is visible around the eclipsing body. If the observer moves closer to the light source, the apparent ...
This diagram illustrates how sunlight is spread over a greater area in the polar regions. In addition to the density of incident light, the dissipation of light in the atmosphere is greater when it falls at a shallow angle. Figure 2 One sunbeam one mile wide shines on the ground at a 90° angle, and another at a 30° angle.
Hale's law states that bipolar active regions have the following properties depending on whether the region is located in the northern or southern solar hemisphere: [2] In the same hemisphere, regions tend to have the same leading polarity. In the opposite hemisphere, regions tend to have the opposite leading polarity.
The Sun, planets, moons and dwarf planets (true color, size to scale, distances not to scale) The following outline is provided as an overview of and topical guide to the Solar System: Solar System – gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the ...
