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.
Auroras typically are seen in the far north, but during high variations in the earthâs magnetic field, theyâre more frequent and can occur farther south. A sighting was recorded in Hawaii in 1859, but that was long before Hawaiian statehood. Florida had a sighting in 2003. Kelly Korreck.
