Different types of benign, or noncancerous, adrenal tumors prove a frequent cause of enlargement of the gland. Adrenal adenomas remain the most common type of benign adrenal tumors, representing over 50 percent of adrenal masses. Uncommon benign adrenal tumors include adrenal cysts and lipomas, or fat-derived tumors.
The Sun provides the energy for the aurora, but particles in the. aurora come from Earthâs own neighborhood in space. The Sunâs. energy is carried toward the Earth in the solar wind, a stream of. electrically charged particles (mostly protons and electrons) ïow-. ing out from the Sun in all directions.
The aurora is the name given to the bands of colored lights seen in the sky at the higher latitudes. The aurora borealis or Northern Lights are seen mainly near the Arctic Circle. The aurora australis or Southern Lights are seen in the southern hemisphere.The light you see comes from photons released by oxygen and nitrogen in the upper atmosphere. Energetic particles from the solar wind strike the layer of the atmosphere called the ionosphere, ionizing the atoms and molecules.owever, the colors of the aurora are different on different worlds because the atmosphere is different. The only requirement for a planet or moon to have an aurora is that it have an atmosphere that is bombarded by energetic particles.
